Sven Leyffer and Alison Ramage Started SIAM Leadership Positions January 1

SIAM is pleased to introduce the incoming SIAM President, Dr. Sven Leyffer of Argonne National Laboratory, and Chair of Board of Trustees, Dr. Alison Ramage of University of Strathclyde. Dr. Leyffer served as President-Elect in 2022 and will serve as President until December 31, 2024. Dr. Ramage became a member of the SIAM Board of Trustees in 2019 and will serve as Chair of the Board for a one-year term through December 31, 2023. The President is responsible for the management of SIAM’s professional and scientific affairs, including making appointments to committees. The Board is responsible for the management of SIAM, taking into account the professional and scientific policies and objectives of SIAM. It also has full legal control of all the assets of SIAM. 

Dr. Leyffer and Dr. Ramage are both longtime members and have been highly involved with the SIAM community throughout their careers. SIAM is grateful for their passion and dedication to the community, and we look forward to their leadership! 

Meet Sven Leyffer 

Born in Hamburg, Germany, Dr. Leyffer obtained his Ph.D. in 1994 from the University of Dundee, working on mixed-integer nonlinear programming problems with Roger Fletcher. He has held postdoc positions at Dundee, Northwestern University, and Argonne National Laboratory. Currently, he is senior computational mathematician at Argonne, and a senior scientist at the Consortium for Advanced Science and Engineering at the University of Chicago.

“I am honored and excited to serve the SIAM community as its next President. As we move beyond the pandemic, I look forward to enhancing our diverse, exciting, and vibrant conferences and broadening access to in-person conferences with new virtual opportunities,” he said.

Dr. Leyffer has remained an active and enthusiastic SIAM member for the past 30 years. He is an associate editor of the SIAM book series on Fundamentals of Algorithms, a 2009 SIAM Fellow, and a member of the SIAM Committee on Science Policy.

Additionally, Dr. Leyffer was awarded the Lagrange Prize in Continuous Optimization in 2006 (awarded by Mathematical Optimization Society and SIAM) with Roger Fletcher and Philippe L. Toint. In 2013, Dr. Leyffer won the 2012 Computational Optimization and Applications Best Paper Prize with Chungen Chen and Roger Fletcher for their paper on nonmonotone filter methods. And in 2016, Dr. Leyffer was awarded the Farkas Prize for mid-career researchers by INFORMS.

Dr. Leyffer looks forward to new initiatives that will strengthen the presence of industry in SIAM, cementing the organization’s unique role as a bridge between industry and academia. He also plans to work with SIAM leadership to nurture SIAM’s dedication to principles of equity, diversity, and inclusion that better the community.

Meet Alison Ramage

Dr. Ramage earned her Ph.D. in mathematics from the University of Bristol in 1991. Her main expertise lies in numerical linear algebra, a vital component of scientific computation that impacts a wide range of disciplines in academia and in technology-based industries. Her particular focus is on developing efficient solution methods for numerical models of partial differential equations, with a primary interest in preconditioners and linear solvers. Currently, Dr. Ramage is a reader in the department of mathematics and statistics at the University of Strathclyde.

“I am really looking forward to working with SIAM leadership and the wider membership as Board Chair, and I am very grateful to the members for their support,” she said. 

Dr. Ramage has been an active and dedicated SIAM member since 1989 and currently serves as a member of the Executive Committee of the Board of Trustees, a member of the Financial Management Committee, and an associate editor of the SIAM Journal on Matrix Analysis and Applications and “Research Spotlights” in SIAM Review.

Further, Dr. Ramage has been awarded the Leverhulme Trust Visiting Fellowship in recognition of iterative methods for flow problems at the University of Maryland in 1999. In 2005, she received the Engineering and Physical Sciences Research Council Springboard Fellowship with Hewlett Packard in recognition of adaptive methods for liquid crystal device modeling. Dr. Ramage is a 2008 Fellow of the Institute of Mathematics and its Applications. And in 2017, she received the Leverhulme Trust Research Fellowship in recognition of preconditioning for novel data assimilation problems.

Dr. Ramage looks forward to continuing her work with SIAM and supporting the development of new initiatives that will benefit the community.
