CSDMS organization
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 provide guidance to the Integration Facility, approve the annual project management plan, advise on major activities, review partnerships, and address 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:
- Reviews proposals from Working Groups for development that are within the priorities of the Annual Science Plan and CSDMS mission;
- Ensures that CSDMS develops and maintains the capability to support collaborative proposals;
- Reviews the ongoing CSDMS business operations through regular meetings, teleconferences, AccessGrid sessions, electronic mail, etc.
- Ensures scientific progress in multiple areas of landscape-basin evolution (LBE) by providing the computational infrastructure needed for improved modeling;
- Ensures the connection of LBE research with related scientific thrusts of scientific computing and Geoinformatics through the establishment of strategic partnerships, and
- 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.
