*  Statement

I am honored to be nominated for the position of ACM President.

As a longtime ACM member, current ACM Vice President, and an industry research leader with strong connections to academia, I believe ACM plays a leadership role in shaping not only the fields of computer science and computer engineering, but also many related disciplines. Through this connection, ACM influences industries built upon computing science and computer engineering expertise and practice.

My vision for continued ACM relevance and influence requires we focus efforts. ACM can significantly shape future research and education directions as well as future industries built on computing foundations. Toward that vision, if elected, I will be a strong voice for deepening efforts in the following areas:

  • Career development: ACM provides the premier platform for career development and growth for all upcoming and established computer science and computer engineering professionals. However, we can do more. A priority area must be appealing more deeply to those in early-stage career. ACM membership currently skews toward mid-to late-stage professionals. Initiatives focused on early CS education and early professional career support will provide solid groundwork for ACM’s growth and continued relevance for years to come.
  • Broader promotion of our content through multi-channel platforms and diverse events: Continued investment for enabling broader access to our growing repository of high-quality, peer-reviewed content for current and future members and beyond is critical. Making our content more accessible will ensure ACM cultivates its position as the community for all professionals associated with computing sciences.
  • Enhance community networking: From our Digital Library to our many events and chapters, we provide essential community platforms for those interested in theoretical and applied computing sciences and related engineering disciplines. We can further leverage ACM’s existing platforms to underscore its place as a lifelong professional network for all aspects of computer science. ACM has an unrivaled opportunity to further develop the social connectivity of its members and to create more platforms where members can share expertise with fellow members and communities beyond ACM.
  • Emphasize ACM’s global impact: Our membership is globally based, yet ACM is often mistaken as an ‘American’ association for CS academics. A focus on deepening our understanding of the needs and perspectives of our very diverse and global community will help ensure we accentuate our leadership as the premier society for computer science and engineering professionals worldwide.

For all of these areas, we must address where to refresh current efforts and where to invest in new efforts.

It would be my privilege, as ACM President, to work with ACM staff, volunteers, and members to address these areas, to focus on thoughtful investments, and ensure ACM’s leadership not only continues but expands and deepens.

*  Biography

Gabriele Kotsis is Full Professor in computer science at Johannes Kepler University, Linz, Austria, and a Distinguished Member of ACM. Receiving recognition for her work from the very beginning (her master’s thesis, submitted at the University of Vienna in 1991, was honored with the student sponsorship award of the Austrian Computer Society, and her Ph.D. in 1995 was honored with the highly prestigious Heinz Zemanek award) was doubtlessly a motivating factor for her and her decision to dedicate her career to research in academia and to the scientific community. In 2002, she was one of the co-founding chairs of the working group for professors in computer science within the Austrian Computer Society (OCG). From 2003 to 2007 she was President of the Austrian Computer Society, being the first female holding this position in Austria. In addition to her two-term presidency at OCG, Kotsis takes an active part in the Editorial Board of the OCG Book Series, in the working group Fem-IT (Association of Female University Professors in IT) and in the OCG award committee.

From 2007 to 2015 she served as Vice-Rector for Research at Johannes Kepler University (JKU). Her responsibilities included the development of R&D strategies and policies within the university, coordination and interaction with national and international governmental organizations and funding bodies, and the establishment of collaborations with other research organizations and business partners. Since 2016, Kotsis has been JKU’s representative in the ASEA-UNINET academic research network, which promotes cooperation among European and South-East Asian public universities. Her active involvement in this network led to her nomination and election as President for the current period, February 2019 to July 2020.

Within ACM, Kotsis has gained a reputation for organizing ACM conferences and workshops. In 2016, she received an award in appreciation of her accomplishments regarding the ACM WomEncourage conference series. Kotsis is a founding member of the ACM Europe Council, serving on the Council from 2008 to 2016. In 2014, she became an ACM Distinguished Member for her contributions to workload characterization for parallel and distributed systems, and for the founding of ACM Europe. Since 2016, she has been an elected Member-at-Large of the ACM Council.

*  Statement

Formal thinking and reasoning together with abstract and geometric modeling are what led me into computer science in the first place. Fascinated by the beauty and purity of binary systems in number theory, I was particularly passionate about Euclid’s algorithm and prime factorization. I was captivated by the understanding of computers as machines being able to unfold the thinking condensed into algorithms. This picture has crystallized clearly over the past three decades of my active life as a computer scientist.

In our discipline, we have advanced linear (Turing-) machines to multidimensional complexity management machines, algorithmic unfolding machines to creative generative machines in artificial intelligence, and deterministic machines to true randomness in executive machine behavior in quantum computing.

These advances have opened the doors to an infinite spectrum of use domains, out of which a few are currently showing remarkable progress. Research prototypes have rapidly developed into living examples of totally autonomic machines (level 4—5 vehicles, drones, …), very-large-scale collectives of cooperative machines (combinations of smartphones, watches, cars, homes, …) or of self-adaptive and locally interactive machines (surgical micro-robots, personal digital agents or twins, …).

ACM (which stands for the Association for Computing Machinery) has already reacted to significant transitions in the past by redefining and reshaping its agenda. Among the many emerging topics, for the upcoming ACM presidency I consider the following as immediately urgent:

  • Computing machinery fighting the CO2 dilemma;
  • Computing machinery fertilizing medical research and health care;
  • Computing machinery protecting democracy.

No other discipline or technology will have more impact on shaping our future than computer science and technology. This implies a major responsibility for our community, not only from a scientific and technical perspective in being able to provide correct solutions, but also from an ethical and societal point of view. Moreover, global problems must be addressed in a global way, independently from particular individual, national or commercial interests. My vision is that ACM, being a global organization, can and must become the platform that enables us to achieve all goals in question.

I feel honored having been nominated for the position of ACM President. ACM is a volunteer organization, and its impact depends on the help and support from all of us. We are a strong community and it will be my responsibility as President to ensure that ACM serves our needs. But we have to take a step forward. Let us work together, across the globe, not only to serve the needs of our own community, but to utilize our knowledge and expertise in “computing machinery” in order to cope with the challenges we are faced within our global society.

*  Statement

The “tetrahedron” formed by mutually interlinking research, education, industrial innovation (the three nodes of the well-known “triangle of knowledge”), and policy is a great framework for conceptualizing the essential activities of a disciplinary professional society. If honored to be elected as ACM Vice-President, I will use my experience from earlier volunteer positions, especially that of ACM Secretary/Treasurer, to help ACM further strengthen its current leadership role within our thriving community, expand its already extensive services across the four areas/nodes of the tetrahedron, and attract, embrace, and benefit all computing professionals globally. Below are some of the directions I care deeply about.

Expand footprint and become the home of all interdisciplinary areas that involve computing: Our field is now on the critical path of most scientific and societal activities, coming itself to an exciting turning point. While remaining current on the purely technological advances, ACM should form strategic alliances with peer scientific societies and have joint activities, expanding and enriching its membership with non-traditional backgrounds.

Include computing as a basic curriculum strand right from the beginning of schooling: Algorithmic thinking is a fundamental skill and ACM should continue its efforts and intensify its involvement in shaping all levels of formal and alternative education. ACM can inspire many young people to follow a career in computing and, thus, lead to a community that is balanced on gender, geography, and age.

Identify major technology-dependent challenges connected with the UNSDGs: ACM should capture the pulse of the computing industry and establish links for better integration of industry-relevant activities. In the spirit of its co-leadership role in events such as the “AI for Good” Global Summit, ACM should coordinate with industrial innovators, establish competitions towards solving global challenges, and support winning teams of inspired community members.

Prioritize social responsibility: Today our creations “run the world” and with this comes great responsibility. ACM should promote its new Code of Ethics widely within the community and also engage with and advise policy makers on cutting-edge technologies, including on their invention without restrictions and their application within clear ethical boundaries.

*  Statement

It is an honor to be nominated for the position of ACM Vice President at this tumultuous time in computing history. Since ACM was founded in 1947, computers have become indispensable tools in many aspects of daily life. Recently, a more profound change has begun: Sophisticated computation is becoming an essential component of many spheres of human activity. People who can understand and exploit computational methods and principles, rather than simply use computers as appliances, now have a decisive advantage over their less computationally astute competitors.

ACM members can address myriad threats now facing society. These threats combine sophisticated computation in critical ways with politics (as in “election hacking”), economics (as in technology-induced unemployment), journalism (as in “fake news”), law (as in mass surveillance in the name of national security), international relations (as in “cyber war”), finance (as in bitcoin speculation), and many other fields. In tackling them, computer scientists will work collaboratively with people in social sciences, law, and many disciplines besides the STEM fields with which we have collaborated for decades. My experiences as a leader of ACM’s efforts in Economics and Computation and, more recently, as a founder of its efforts in Computer Science and Law have given me the skills and perspective needed to support ACM members in wide-ranging, interdisciplinary work.

As the premier organization of computing professionals, ACM must convince young computer scientists to join and participate. Our conference proceedings and journals are highly valued, but, with ArXiv preprints readily available and access to the Digital Library through employers, many people feel no need to join. Similarly, ACM-sponsored awards are prestigious, but non-members are eligible for many of them. If elected, I will conduct a series of structured discussions with non-members to learn their views on the proper role of a professional society.

On an optimistic note, ACM members are increasingly interested in real solutions to serious problems, such as carbon-intensive conference participation and limited access to published research. If elected, I will work to accelerate our transition to sustainable practices such as online conferences, remote participation in face-to-face conferences, and fully funded open access publication.

*  Statement

I am honored to be nominated for ACM Secretary/Treasurer.

As the ACM SGB Chair, I am proud to have participated in the steps that ACM has taken as a leader in ethics, inclusivity, Open Access and in providing independent technical policy advice to the public. These efforts should be enhanced and continued.

The computing community is expanding to include a diverse set of backgrounds, locations, and skillsets. ACM is positioned through publications, conferences, chapters, and councils to be a conduit for this diverse community. Digital technologies provide ways to increase connectivity through remote engagement, online media and social networks. The technologies encourage greater participation which can only enrich our field. I look forward to helping expand digital opportunities provided by ACM.

The Digital Library (DL) is a valuable funding source for ACM that supports activities that include the Special Interest Groups (SIGs) and Chapters. ACM is actively deploying and innovating with DL Open Access publication models. A revamped DL is in development that enhances the personal experience for research and education. I believe that we need to continue such developments, increase practitioner content, and add more reproducibility artifacts to the DL.

The SIGs interact with a significant cross-section of our community through conferences and other activities that provide a significant income stream to ACM. Continued engagement with the SIGs is crucial in the areas of volunteer recruitment, retention and development. Of equal importance is membership retention and the diversity of volunteers, speakers and attendees.

It would be my privilege to serve as Secretary/Treasurer and continue working with ACM staff and volunteers in providing services to our community.

*  Statement

I have been a member of ACM for 38 years. I am honored to have been nominated as a candidate for Secretary/Treasurer of ACM.

I strongly believe that the field of computer science is today more exciting than ever.

We see fundamental advances, such as those made possible by AI, IoT systems, quantum computing, and 5G technologies, and unprecedented opportunities for novel applications. Our technologies have a fundamental role in shaping society. However key questions need to be addressed including AI and data ethics, data transparency, personal privacy versus collective security, and sustainability. Answers to those questions as well as others posed by the pervasive use of our technologies must be given by taking into account a broad multidisciplinary perspective. If elected, I will work together with the ACM Executive Committee and the many volunteers and leaders in ACM to make sure that ACM has a central role in fostering discussions and initiatives to answer those questions as well others posed by society concerning our technologies. I will also focus on important matters, such as broadening diversity in our field, supporting younger researchers, open access to data and publications, the role of conferences vs. journals, industry engagement, large-scale research infrastructures, and last but not least making sure that ACM stays technically relevant by organizing workshops and conferences on new emerging technologies and applications.

The ACM Secretary/Treasurer also oversees ACM’s finances. If elected, I will leverage my past experience as a volunteer in different roles to help ACM maintain and enhance its current financial stability, while at the same time ensuring that ACM funds are used to best serve our research community.

*  Statement

Computers have become 1+ trillion times more capable since the introduction of transistors, and computer science’s innovations in the analytical/algorithmic and engineering domains have been equally remarkable. Our field has also added a strong empirical dimension, both benefiting from and facilitating the vast growth of computing worldwide. Unsurprisingly, this innovation is impacting us all: as information technology professionals and as citizens, and it is affecting the ACM.

With their great reach and capability, our field has delivered amazing and sometimes insufficiently understood benefits. But society is rightly concerned with the downsides of technology, both actual, potential, and sometimes even fictional. Those concerns, if not properly addressed, run many risks, including to ourselves and the opportunities we collectively have to improve our world. Without our attention, idealistic youth might even stop flocking to our field.

If I am elected an ACM Member at Large, I will use my broad perspective to provide both strategic and operational counsel to ACM. For example, I will seek to improve the relevance of ACM to our diversifying field; to push for open access publication while ensuring a sound business model; to catalyze the publication of novel software artifacts as an intellectual pursuit; to maintain our proudly international organization in an era of increased nationalism; to accelerate the diversification of computing to all who can contribute; to thoughtfully lead discussions of policy and ethics that benefit society, our field, and our membership; and to balance the diversification of our field (e.g., the rise of data science as a quasi-parallel discipline) while promoting the core of our field. I hope to contribute to these topics and many more.

*  Statement

It is a privilege to be nominated for Member-at-Large. I’ve been an ACM member since I was a Ph.D. student, and have been constantly amazed by the various educational opportunities and scholarly events that ACM offers to our community, and I am equally impressed by the many dedicated ACM members for their passion of pushing forward computing technologies in all aspects of human activities.

If elected, I would like to help expand some key activities along these lines.

  • Promote volunteering services from Asian countries (e.g., China, India, Japan and Singapore, etc.) and European countries (e.g., England, France, Germany, Italy, etc.).
  • Promote closer collaboration between IT companies and academic researchers around the world.
  • Promote more volunteering participation in organizing educational and academic events.

Information technology is crucial to our economic growth, and ACM has the responsibility of creating more public awareness of IT technologies, and how these technologies may transform our jobs and working environment. ACM also needs to have a firm commitment to relay the advantages and pitfalls of some of the latest computing technologies to different government agencies around the world. My academic training, industrial experience, and relationship with government agencies gives me the unique viewpoint of how to promote the above items. But, to be successful, I also need all ACM members to join hands and help out so that our community can make a bigger impact.

In summary, we now have the wonderful opportunity to shape a better and brighter future for our next generation. Let’s join hands to create a better place for our future generations.

*  Statement

I am honored to be nominated as a potential Member-at-Large of ACM Council. While I have supported a variety of ACM conferences, activities, and initiatives over recent years, especially through the ACM Europe Council, I am enthusiastic about serving ACM more widely to further support and develop a diverse and impactful international computing community. It is clear we face a number of challenges—and opportunities—as a discipline and community over the coming years. There are broad social, cultural and economic imperatives; for example: the widespread impact of technology, data and computational processes on our lives; digital innovation, automation and the future of work; shifting legal, ethical and professional responsibilities; national and international collaborative research agenda (funding, industrial strategies, mobility, open access/data/research); dramatic changes to our education systems: curriculum reform, qualifications, accreditation and certification, and a range of challenges for universities; and supporting the careers and professional development of a diverse global computing/IT profession.

In a rapidly shifting political and policy landscape, much is possible—but this requires more explicit international collaboration with national academies and professional bodies, as well as with industry and the general public. Building on my previous experience and networks as an academic, policy advisor and extensive industry non-executive roles (including multibillion pound utilities and public services), I would relish the opportunity to serve as a Member-at-Large on ACM Council.

*  Statement

I have been an active member of ACM for my entire professional career and would appreciate the opportunity to serve as a Member-at-Large on the ACM Council. As a current Council member, I have worked on the Future of Computing Academy and new technology directions. Although ACM is widely recognized as the premier professional computer society, with strong commitment from volunteers, there are challenges ahead.

ACM has a long history of advancing computing through conferences, publications and resources for education and professional development. The digital library will have to continue to evolve to address the need for open access and the inclusion of rich media, open data, and other resources for students, practitioners and researchers. There are also new opportunities to augment conferences to better support remote participation to mitigate the need for travel and broaden participation.

Many of the challenges that the computer science community faces today will not be solved by a single discipline in isolation and would benefit from interdisciplinary perspectives. I would like to see us develop opportunities for people with different backgrounds to come together to address important technical and societal problems.

I will also work to continue to broaden participation from individuals with diverse backgrounds and to support their career development. Finally, I would like to see ACM take a more proactive role in informing policy around important issues such as personal privacy, and network and data security.

I believe that my sustained service to ACM and multidisciplinary background provide me with perspectives that would be an asset to ACM in addressing computing challenges moving forward. If elected, I would be honored to serve as a Member-at-Large on the ACM Council.

*  Statement

I am honored to be nominated as a candidate for the Member-at-Large office. I joined ACM as a grad student over three decades ago, and treasure the support I received from SIGPLAN for attending a major conference.

As ACM has grown internationally, especially in Asia, it must continue to reach out: making its flagship events, activities, and publications accessible to the growing diversity (in country, gender, age, profession) of its membership. I will work toward extending ACM’s culture of community, collaboration, mutual respect, inclusiveness, and spirit of volunteering to researchers and professionals across the world.

As Editor-in-Chief of ACM Books, I consider it important that young researchers and working professionals be able to access the best pedagogical and research material in a timely and affordable manner. I believe that ACM must transit soon to an open access model for its research publications that is equitable for researchers across the world. It should also provide practical technical material for working professionals in its Digital Library. I believe we are inventive enough to manage this transition without impacting ACM’s other major activities.

With computing finding its way into every aspect of our lives, “advancing computing as a science and profession” means:

  • imbuing in every individual (across nationality, age, gender, etc.) a computational way of thinking;
  • educating society about opportunities and threats that new technologies pose;
  • disseminating the ethics and ethos needed for creating responsible computing professionals.

I would like to see ACM take a proactive role in influencing international policies on important societal issues such as fairness, personal privacy, software and system safety, and network and data security.

*  Statement

I am honored to be nominated to run for a Member-at-Large. As Co-chair of the ACM Education Board, I’ve served on the Extended Executive Committee of the ACM for four years. That experience gives me a deep appreciation for the issues facing ACM and provides the opportunity to be effective from day one as a Member-at-Large.

My main goals are working to better serve the needs of the membership, specifically pursing opportunities to push for more open access models for publication, increasing development of content relevant to practitioners, and more fully realizing ACM’s mission to be a truly global association. Open access in publications is an area where ACM needs to take a stronger stance, both internally by charting a part for opening up the digital library, as well as externally by being an advocate for more open access to scholarly research in general. This is the direction the field needs to go and ACM should be leading.

Additionally, I am deeply concerned about ethical issues that have become commonplace in computing and believe that ACM needs to take a more active role in educational and policy activities to address these issues. Ethics in technology is an active area of work for me, including teaching a multidisciplinary course, for which we produced professionally written case studies on several topics (algorithmic decision-making, autonomous systems, data privacy, the power of large computing platforms/companies) and made them all freely available. While updating the ACM Code of Ethics was a good step, I believe that ACM needs to be more active in engaging with the policy conversations around how technology should be regulated for the benefit of all.

I look forward to continuing to serve ACM and I appreciate your consideration for a Member-at-Large seat.

*  Statement

I have been an active member of the ACM since my days as a graduate student (30+ years!)—I am honored by this nomination and would welcome the opportunity to contribute to the ACM.

This is an extremely exciting time for our field. Advances in computing have led to breakthroughs that are changing how we solve problems in all disciplines and to new technologies and products that have impacted all sectors of the society and all aspects of daily life, providing unprecedented opportunities for computing researchers and generating tremendous interest in our field. This is in turn driving demand for and innovation in computing education.

These developments provide many opportunities for the ACM to take leadership and have impact. As the field expands, we need to ensure the ACM portfolio covers all relevant research areas, including multidisciplinary areas in which computing plays a central role (e.g., robotics), and to ensure the most important and impactful research results are published in our conferences and journals and are available to all. Additionally, there are many societal issues that ACM has an opportunity, and in many cases an obligation, to play a leading role in shaping the conversation. This includes being viewed as a trusted and honest source of information about issues related to computing, serving as an advocate for lifelong computing education, and ensuring that the entire population feels welcome to, and indeed does, engage in all aspects of our profession.

Given the myriad opportunities, ACM, and in particular its society-level bodies such as the ACM Council, needs to strategically determine where, when, and how to engage.

If elected, I would be honored to serve as a Member-at-Large of the ACM Council.
