In the area of automatic differentiation, the main focus is on the development of robust tools for the differentiation of C and C++ codes, and a modular design and implementation of automatic differentiation tools, enabling rapid AD algorithm development and reuse of differentiation strategies by front-ends for different programming languages. In the area of performance modeling and optimization, Boyana is performing research on performance bounds modeling and source analysis tools for estimating performance bounds of C and C++ code. She is also developing annotation-based empirical performance tuning tools, as well as component infrastructure for managing performance experiments and data. She has authored or co-authored over 50 publications and co-edited a volume on automatic differentiation. Boyana's interest in CSDMS centers on the application of component technology to (1) provide consistent interfaces to software developed within CSDMS and (2) ensure that the component software infrastructure and tools meet the needs of CSDMS researchers. Boyana accepted the responsibility to serve as a member of the CSDMS Steering Committee in September, 2009.

Professor, University of Virginia, Department of Environmental Sciences. Pat’s primary research interest is in sediment erosion, transport, and deposition in river, coastal, and wetland environments. Her current research topics include storm-driven transport and the formation of sedimentary strata on the continental shelf, erosion and deposition on tidal salt marshes, flow-sediment-vegetation interactions in shallow coastal bays, mud dynamics in meso- and macro-tidal flats, wave-formed ripples, impact of climate change on barrier-bay-marsh morphology, and sediment associated contaminant transport. Pat has been a tireless advocate of CSDMS. She's served the CSDMS community since it's inception; first as Chair of the Marine Working Group from 2007 to 2012 and then as Chair of the Steering Committee from 2012 to 2017. Pat re-joined the Steering Committee in April, 2020.

Raleigh Martin

Ex Officio Member, Steering Committee Raleigh Martin Director-Geoinformatics Pgm, Div. Earth Sciences National Science Fdn (NSF), 2415 Eisenhower Ave., Alexandria, VA 22314 Email: ramartin@nsf.gov Tel: +1 703-292-7199

Dr. Raleigh Martin is Director of the GeoInformatics program at the National Science Foundation. His previous research focused on aeolian sediment transport processes. In his more recent positions, Raleigh leverages scientific understanding of Earth and environmental processes to inform federal, state, and local policy responses to climate change and other environmental challenges. He is dedicated to making science and data more open, transparent, and accessible to advance scientific discovery and inform policy decisions. Raleigh received his Ph.D. in Earth Sciences from the University of Pennsylvania. Prior to joining NSF, Raleigh was a AAAS Science & Technology Policy Fellow and served the U.S. House of Representatives as a Congressional Geosciences Fellow on the House Select Committee on the Climate Crisis. In 2020, he became the Program Manager at NSF for CSDMS.

Brad Murray

Ex Officio Member, Steering Committee Brad Murray Division of Earth and Ocean Sciences Duke University 334 Old Chem, Box 90227 Durham, NC 27708 Email: abmurray@duke.edu Tel: +1-919-681-5069

Past Chair, Steering Committee Brad received all his degrees from the University of Minnesota –a BA (Journalism) and a BIS (Science) in 1986, a Masters (Physics) in 1990, and a PhD (Geology) in 1995—and was a postdoc at Scripps Institution of Oceanography until 1998. He is currently Professor of Geomorphology and Coastal Processes at Duke University. Brad studies landscape evolution and pattern formation in a variety of environments, but concentrates these days on the morphodynamics of shallow sea beds, tidal marshes, and sandy and rocky coastlines. Brad uses relatively simple numerical models to explore hypotheses, usually motivated by field observations, about how landscapes in these environments come to be and how they might respond as the climate forcing shifts. Increasingly, this research involves two-way couplings between physical and biological (including human) processes. Brad is a long-term community supporter and served as Chair of the CSDMS Coastal Working Group since its inception in 2007 until August of 2017 and SC Chair from 2017 to 2022.
