CSDMS organization

CSDMS Executive Committee

The Executive Committee (executive committee chair, steering committee chair and the working group chairs) is the primary decision-making body of the CSDMS, and meets twice a year to approve the annual science plan, the semi-annual reports, the management plan, budget, partner membership, and other day-to-day issues that arise in the running of the CSDMS. The Executive Committee also develops the By-Laws and Operational Procedures, to be approved by the Steering Committee. The Executive Committee develops and implements the 5-year Strategic Plan.

The Executive Committee further:

1. Reviews proposals from Working Groups for development that are within the priorities of the Annual Science Plan and CSDMS mission;
2. Ensures that CSDMS develops and maintains the capability to support collaborative proposals;
3. Reviews the ongoing CSDMS business operations through regular meetings, teleconferences, AccessGrid sessions, electronic mail, etc.
4. Ensures scientific progress in multiple areas of landscape-basin evolution (LBE) by providing the computational infrastructure needed for improved modeling;
5. Ensures the connection of LBE research with related scientific thrusts of scientific computing and Geoinformatics through the establishment of strategic partnerships, and
6. Ensures transparency of governance and intellectual involvement of community via reasonable criteria for partner membership and a mechanism that allows community input.

Executive Committee Chair; CSDMS Executive Director Greg Tucker is a Professor of Geological Sciences at the University of Colorado at Boulder and is a fellow of the Cooperative Institute for Research in Environmental Sciences (CIRES). His research focuses in the area of computational and theoretical geomorphology. He brings his training in geosciences, archaeology, and numerical computing to bear on understanding the dynamics of earth’s surface topography, both in the context of the “deep time” evolution of mountain ranges and other landforms, as well as contemporary processes such as river flooding, debris-flow erosion, and gully formation. In advancing our understanding of landscape dynamics, he and his students combine field measurements, digital terrain data, and numerical modeling. In recognition of this work, Prof. Tucker was awarded the Ralph Alger Bagnold Medal by the European Geosciences Union in 2012. Prof. Tucker has authored or co-authored over 100 journal publications and book chapters. He is also a co-creator of the popular CHILD landscape evolution model. He currently leads an NSF-supported project to develop Landlab, a contribution to the Community Surface Dynamics Modeling System that provides a Python-language library for efficient creation and coupling of two-dimensional numerical models. Prof. Tucker is a graduate of Brown University, with a BA in Anthropology, and of Penn State University, with a PhD in Geosciences. Prior to joining CU-Boulder, he was a postdoctoral research associate in MIT’s Department of Civil and Environmental Engineering, and later a faculty member at Oxford University’s School of Geography and the Environment. He was elected CSDMS Deputy Director in November of 2015 and assumed the role of Executive Director in October, 2017.

She develops numerical models to explore sediment transport processes, morphological change, depositional patterns and stratigraphy. Field observations of rivers and deltas worldwide guide her design of models and critical assessment of their predictions. Overeem has published over 50 peer-reviewed articles in journals like Nature Geoscience, GRL, Journal of Geophysical Research, as well as in domain journals like Sedimentary Geology, Basin Research and The Cryosphere. Her current projects with students and postdocs focus on modeling sedimentation and its impacts on delta sustainability, with special emphasis on the Ganges-Brahmaputra delta, and on rivers and deltas in a rapidly changing Arctic region, with field projects in Greenland and Alaska. Overeem leads a NSF-funded project to develop community cyberinfrastructure for modeling of permafrost processes. She won the National Oceanographic Partnership Program Award for work on Arctic Coastal Erosion in 2010. Overeem worked as a postdoctoral fellow with Jaia Syvitski between 2002-2005, and then became an Assistant Professor in Applied Earth Sciences at Delft University.

CSDMS Steering Committee

The CSDMS Steering Committee (SC) is comprised of 10 members: 8 selected by the EC to represent the spectrum of relevant Earth science and computational disciplines, and 2 selected by Partner Membership. The cognizant NSF program officer or his/her designate, and the Executive Director or his/her designate, serve as ex officio members of the SC. During SC meetings, there may be occasions when these ex officio members would exclude themselves from discussions.

The Steering Committee meets once a year to assess the competing objectives and needs of the CSDMS; will comment on the progress of CSDMS in terms of science (including the development of working groups and partner memberships), management, outreach, and education; and will comment on and advise on revisions to the 5-year strategic plan. The Steering Committee will provide a report to the Executive Director at the close of its meeting, to which s/he will respond within two weeks.

Brad Murray

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

Steering Committee Chair 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. In August 2017, he accepted election (by unanimous approval of the full CSDMS community) to CSDMS Steering Committee Chair.
