Candidate Statement:
My career as an industrial mathematician has been shaped by my work at The Aerospace Corporation, which operates a nonprofit Federally Funded Research and Development Center for the U.S. government. I have strived to solve real-world problems of interest to my customers in the defense and national security arenas through the development and application of numerical algorithms. By staying involved with SIAM in a variety of ways over the years, I have been able to foster new connections as well as maintain old connections with other applied mathematicians & computational scientists in academia, industry, and the national labs.  At Aerospace, I have worked to form a community of SIAM advocates by promoting the benefits of SIAM Corporate membership, distributing SIAM News, and encouraging the hiring of applied mathematicians and computational scientists. 

My passion for SIAM, its members and its activities, was born during my graduate school days when I first delved into the study of differential-algebraic equations. I was charmed by the inclusiveness of SIAM members, namely SIAM’s diversity that enveloped students, professors, researchers, and industry practitioners all together. As the facets of diversity (e.g., gender, nationality, race, ethnicity, age, industry/academia) of SIAM members has evolved tremendously over the years, it is critical that we work to improve diversity in SIAM leadership (Board, Council, Committees) and conferences (speakers, organizers, students). 

SIAM already supports many programs such as the Visiting Lecturer Program (VLP), Career Fairs, and Student Chapters which could be utilized to build new connections between industry and academia. Student Chapters should be encouraged to invite speakers from the VLP at least once a year. SIAM can also help by identifying individuals (advocates) at SIAM Corporate Institutions to help build these relationships as well. For example, SIAM Corporate Institutions should be a source of new speakers for the VLP, and should be encouraged to invite speakers from the VLP to their company. 

I would like to continue to serve SIAM members by working as a member of the SIAM Board of Trustees and associated committees. If re-elected, I promise to work to insure that financial & operational decisions are guided by SIAM’s mission in applied mathematics and computational science: “to advance research and applications, to foster communication among mathematicians, engineers, and scientists, to build this community, and to support the next generation.”

Candidate Statement: 
This is a time of amazing opportunity for the mathematical and computational sciences. The availability of data in all areas of science, engineering and medicine is both unprecedented and growing extremely rapidly. The need for tools to analyze the data, models to facilitate understanding and prediction of the underlying processes, and algorithms and software to enable modeling, data analysis, and data manipulation, has never been greater. At the same time, there are some enormous challenges for science and for scientific societies, including SIAM. As a society, we need to become more effective in identifying new results with potential for impact to society, and find effective ways to communicate them to the general public. And, we need to strive for inclusiveness in SIAM’s leadership and in all of its activities. I am running for SIAM Board because I believe these are critical challenges that will require fundamental change. I would like to try to help facilitate thoughtful discussion and actions on issues that will affect all SIAM members.

Candidate Statement: 
SIAM's outstanding publications, excellent conferences and inclusive policies have made it a leading international professional organization in applied mathematics. Moving forward, it is important that the SIAM Board is strategic in thinking about future opportunities for, but also threats to, these and other key SIAM services. I would also like to see the continuation and expansion of the help and encouragement offered by SIAM to students, younger career mathematicians and minority groups. SIAM provides a unique forum for facilitating interaction between new and established researchers in academia and industry and those opportunities should be exploited as fully as possible. I think that it is important that bodies such as the Board reflect the fact that an increasingly large proportion of SIAM members live outside the U.S., and I believe that SIAM should continue to strengthen its international links with continued initiatives such as holding joint conferences outside North America and extending the possibility of reciprocal membership with other mathematics societies worldwide.

Professional Memberships:
SIAM, International Council for Industrial and Applied Mathematics, GAMM (Germany), European Mathematical Society, ECMI, EU-MATHS-IN, KWG (Netherlands), Asia Pacific Consortium of Mathematics for Industry (APCMfI).

Research Interests:
Mathematical modelling, simulation and optimisation (MSO) for industry, numerical linear algebra (especially for indefinite systems), singular perturbations. Current main field: model order reduction (structure preservation, coupled problems, DAEs, various applications). Main applications: semiconductor device and electronic circuit simulation, energy-related topics. 


Candidate Statement:
These are exciting times for SIAM. On the one hand, the future development of industry and society exhibits strongly increasing complexity and at the same time ever-shorter innovation cycles. On the other hand, digitisation and the internet of things have led to an explosion of data and information. Without novel mathematics-based computational tools and paradigms we will not be able to manage these challenges. SIAM’s journals and conferences can play a vital role in this, but new incentives are needed to optimally benefit. Increased involvement in industrial and societal challenges is required, and is crucial for sustaining, and even improving, the financial health of SIAM. Another important trend is that many of our students are taking up jobs in industry, much more than before, which has addititional implications for the (educational) activities of SIAM. A previous president of SIAM has already indicated that the “I” in SIAM is too small, and I see it as an important task to improve on this substantially: more industry involvement in all of SIAM’s activities, increased industrial sponsorship of conferences, preparing our students better for their future careers, developing new ways of working with industry. Having worked in industry for more than three decades, I have clear views and ideas on how to achieve this, and I will be happy to share these when serving on the Board.

Another important aspect is SIAM’s role on a worldwide scale. Besides SIAM, there are many organisations for industrial and applied mathematics. It is vital for our discipline to improve the coordination of activities, and to ensure that it receives the recognition it deserves. SIAM, being a large and financially sound organisation, can play a key role in this process, by initiating and developing new ways of cooperation: together we are strong! Having been involved actively in several organisations (ECMI, EU-MATHS-IN, APCMfI, ICIAM) for many years, I will bring this experience to the Board and suggest ways to improve the situation for industrial and applied mathematics on a global scale, bringing mathematics forward as a key enabling technology.

It would be an honor for me to have the opportunity of serving on the Board of Trustees, and share my experience in industry as well as my experience in industrial/applied mathematics societies.

Professional Memberships:
SIAM; American Institute of Aeronautics and Astronautics (AIAA, Associate Fellow); International Society for Structural and Multidisciplinary Optimization (ISSMO).

Research Interests:
Methods for modeling, design optimization, and control of cyber-physical-human systems, including mechanical artifacts and heterogeneous adaptive systems, such as future transportation systems; concepts of trust and trustworthiness in systems governed by autonomous computational intelligence and human-machine teams with a high degree of machine autonomy.


Candidate Statement:
SIAM’s invaluable service to its worldwide community of researchers and practitioners, as well as to the domain of applied and computational mathematics, is evident. Therefore, I will limit my statement to a description of a problem to which, I believe, SIAM has an opportunity to make a critical contribution. 

Self-adjusting systems (SAS) and adaptive systems, in general, are spreading from well-defined activities, such as manufacturing, to complex activities with multi-faceted human interactions and decision making, such as those involved in piloting an aircraft. SAS’ ability to solve large problems of certain types far exceeds that of humans’. However, until SAS are proven and perceived to be as or more adaptable than humans, and resilient in the face of unanticipated faults and variable conditions, humans remain in ultimate control of decision making, while supported by machine-based information and advice. If the human is to remain the ultimate resolver of a problem, the problem must not be more complex than the human can solve. Which raises the question of a machine’s role. Moreover, human-machine interaction in many domains has numerous well-known and well-documented difficulties, including lack or excess of trust, both of which can lead to serious problems, especially in time-critical and safety-critical domains. Given the increasing complexity of such domains, e.g., the skies dense with anticipated unmanned aerial vehicles and air taxis, SAS will acquire growing decision-making authority. When should machines have authority? Under what circumstances is machine decision making trustworthy? 

Traditional validation and verification (V&V) approaches do not answer these questions for SAS. A popular view holds that these problems will be resolved in the domain of autonomous surface transportation. However, despite impressive advances, arguably, the current safety case for autonomous cars is “keep your hands on the wheel”. Airspace is less forgiving. 

Understanding the properties and effects of autonomous computational decision making in safety-critical environments requires a close collaboration of applied and computational mathematicians with colleagues in specific engineering domains, such as airspace. SIAM can play a vital role in promoting practical partnerships with domain researchers through active interaction with societies, such as the American Institute of Aeronautics and Astronautics. Calling the attention of faculty and students in applied mathematics departments to numerous unsolved problems in autonomous systems carries not only valuable educational benefit, but a wider societal benefit as well. After all, everyone will have to coexist with decision-making machines.

Research Interests: 
Numerical Linear and Multilinear Algebra, in particular: linear and nonlinear eigenvalue problems, preconditioning of linear systems with block structure, matrix equations, and low-rank tensor approximation and calculus; Model Order Reduction; Numerical Methods in Systems and Control Theory; PDE Constrained Optimization; and High-performance and Power-aware Computing.

Application areas include Computational Nanoelectronics/Circuit Simulation, Computational Electromagnetics, Micro-Electro-Mechanical Systems (MEMS), Computational Fluid Dynamics, Process Engineering, Machine Tool Design, Energy Networks, and Computational Physics/Chemistry.


Candidate Statement:
SIAM is the worldwide leading organization in applied and industrial Mathematics. Beyond its obvious role in structuring the research and funding landscape inside the U.S., it has an increasing impact internationally through its international sections, student chapters, and co-operations with other applied mathematics organizations. Being located in Europe and having been/being actively involved in the governance of GAMM (2010-16) as well as the International Council for Industrial and Applied Mathematics (as GAMM representative) and the EMS (as council member since 2012), I believe outreach activities should be continued and strengthened. This should, e.g., include joint conferences with mathematical organizations outside the U.S. and supporting activities in underdeveloped countries, in particular those having none of their own applied math organizations.

The SIAM Student Chapters are a very attractive instrument for outreach for doctoral students. Activity groups structure the research areas covered by SIAM. International and national sections provide special opportunities for joint regional activities. There might be a need to also have special instruments appealing to postdoctoral researchers in their early career.

Another important issue for the future of SIAM is to steer the successful and excellent publications program through the current turbulent transition phase in the scientific publication world. It is necessary to embrace new areas in applied and industrial mathematics, like SIAM did most recently with the data sciences by launching the SIAM Journal on Mathematics of Data Science. SIAM should continue to define the highest scientific standards in the editorial and reviewing processes, and should transfer this high quality publishing philosophy to new journals and potential other scientific dissemination platforms. SIAM should serve as a role model in this process, and can set standards that would hopefully also be followed by traditional publishing houses at some point. But SIAM also needs to discuss and potentially implement new elements of electronic publishing, like online reviewing and/or commenting functionality, running computational experiments reproducing published results online, etc.

Candidate Statement: 
Being a SIAM member for more than thirty years and having served the community in various roles, I am honored to be nominated as a candidate for the SIAM Council.  It has been gratifying to witness the continuing growth of SIAM over the years in academia, industry and national labs, in the U.S. and the rest of the world, and to take part in its activities serving students and young professionals. I look forward to the new opportunity, if elected, to work with other members of the Council and SIAM to address issues facing the community. In particular, it will be great to explore what more SIAM can do to increase its appeal to the younger generation, to take a bigger role in data and machine learning research (including areas such as the analysis of scientific data, intelligent scientific computation, robust design and ethical use of algorithms in data and AI), to strengthen ties and to promote collaboration and joint activities between the different SIAM student chapters, between different sections and activity groups, and between SIAM and other professional societies in related disciplines and from different geographical regions.

Candidate Statement:
SIAM has been the most important professional society that brings together applied mathematics and computing to solve many real-world problems. It fosters the rapid growth of the interdisciplinary fields in computational science and engineering, with journals and conferences of the highest standard.  As a Council member for two and a half years, I have participated in fruitful discussions about improving SIAM Activity Groups, conferences, journals, and prize and award programs. I visited a number of SIAM Student Chapters at various universities. I believe SIAM can play a more prominent role in (1) facilitating closer collaboration between theoreticians and practitioners through joint appointments, conferences, and publications, (2) providing more opportunities to involve graduate students and junior scholars, and promoting diversity, (3) nurturing nontraditional areas that require cross-cutting technologies, such as analysis of experimental data from scientific instruments. In my capacity as a Council member, I would like to continue working with the SIAM community in developing better approaches in these areas.

Research Interests:
Uncertainty quantification, ocean and climate dynamics.


Candidate Statement: 
Among the various SIAM executive groups, the Council is where diversity and creativity can be put to very good use in fostering innovation. 

SIAM could be a solution to the following problem: bringing talented scientists up to date on research by increased participation: I would like to draw more people from around the world to our meetings and topical conferences (especially) by exploiting electronic means of participation, for people who cannot attend meetings. SIAM has the knowledge base and the member expertise to offer continuing education credit courses of interest to industry and government scientists. A way I can imagine we can encourage strong network connections is to offer industrial problems workshops at meetings, akin to NSF-sponsored industrial workshops  I would also like to see co-locating certain conferences in order to offer special sessions from SIAM and from other learned societies, encouraging greater scientific cross fertilization. 

I think innovation is a necessary condition to draw young, new, and diverse members from around the world and from all disciplines, and it is innovation that keeps SIAM healthy and evolving.  

I am excited and honored to be considered to serve on the SIAM Council.

Research Interests: 
Convex conic optimization: algorithms, theory and applications, in particular, for large-scale semidefinite programming. Fast algorithms for large-scale optimization problems in machine learning and statistics. Iterative methods for large linear equations arising from optimization. 

Candidate Statement:
Optimization has been an essential part of research in business and engineering, and is increasingly being rigorously applied in data science, statistics, physical sciences, and medicine. The SIAM optimization community has established a large body of knowledge on optimization theory and developed powerful algorithms and software packages for practical computation. The rapid development of practical optimization algorithms is, in large part, made possible by the foundation built by SIAM’s numerical linear algebra, scientific computing and numerical analysis communities, as exemplified by the LAPACK and sparse matrix factorizations libraries that are routinely used as the underlying engine for efficient computation in an optimization algorithm. It appears that several research areas in SIAM, such as imaging science, data science, computational science, and numerical analysis, would benefit from more interactions with optimization and vice-versa. I would like to see more cross- fertilization of these areas to make SIAM a unique avenue for the dissemination of research in building models, establishing theoretical results and developing powerful algorithms for applications in this age of data science and artificial intelligence. 

I would also hope to see more interactions and synergy between the activities organized by the applied mathematics and optimization communities in Asia with SIAM’s activities. 

I am honored to be nominated for election as a Council member. If elected, I would do my best to contribute to SIAM’s longstanding effort as the prime driver of research activities in applied mathematics and its applications for the benefit of society.

Candidate Statement: 
This is an exciting time for applied and computational mathematics. Traditional areas (such as computational science & engineering) have made and continue to make significant contributions to society. At the same time, younger parts of our field (such as mathematics of data science) have been steadily increasing in importance.

One of the great opportunities for SIAM is to promote both the younger and older branches of our field and to establish a rapport between them, both in our research and educational programs. I also think it is important to support the careers of younger scientists so that we can establish the next generation of leaders in our field.

As a first step in this program, I worked with Tammy Kolda to establish the SIAM Journal on Mathematics of Data Science (SIMODS), which will publish its first issue in the fall. I am also serving as the co-chair of the first SIAM Conference on Mathematics of Data Science, to take place in 2020. 

At the same time, we do face a few serious challenges, such as uncertainty about federal research funding and the maintenance of our journals as publishing models evolve.

With these opportunities and challenges in mind, I am grateful to be considered for re-election to the SIAM Council.
