US Representatives to the Standing Scientific Group on GeoSciences

SridarSridhar Anandakrishnan
Pennsylvania State University 

Sridhar Anandakrishnan is a Professor in the Department of Geosciences and the Earth and Environmental Sciences Institute at Pennsylvania State University.  His research interests include glaciology and geophysics leading to a better understanding of the impacts of climate change on the Cryosphere.  Dr. Anandakrishnan has conducted geophysical research in Antarctica and Greenland in order to better characterize the englacial and subglacial environments.  He works with numerical modelers to improve their models based on field observations, and to improve projections of sea level rise. He is a member of the National Academies’ Polar Research Board and a Fellow of the American Geophysical Union.  Dr. Anandakrishnan received his Ph.D. from the University of Wisconsin, Madison.


SamanthaSamantha Hansen
University of Alabama

Samantha Hansen is an Associate Professor at the University of Alabama’s Department of Geological Sciences.  She seeks to advance understanding of fundamental geodynamic processes, such as volcanism, mountain building, continental rifting, and craton formation, by emphasizing earthquake seismology, active tectonics, and the analysis of seismic data.  She is currently evaluating tectonic models for Antarctica and is the lead investigator for the TAMNNET project, which deployed 15 seismic stations across the northern Transantarctic Mountains.   She has an NSF CAREER award for Antarctic seismology, and she has worked in collaboration with the Korean and Italian Antarctic research programs.  She has a PhD in Geology and Geophysics from the University of California, Santa Cruz.

BerryW Berry Lyons
Ohio State University (Term ends 04/2012) 

Berry Lyons is currently the Director of the School of Earth Sciences at the Ohio State University.  Lyons and his research group currently conduct research on three specific topics: 1. the biogeochemistry of Antarctic terrestrial/aquatic ecosystems and how they response to climate change, 2. the interactions and rates of chemical weathering, erosion/sediment transport and carbon dynamics, especially in small, mountainous watersheds and polar regions, and 3. the impact of urbanization, suburbanization and agricultural activities on water quality. He is a Fellow of GSA, AAAS and AGU. He is a Co-Principal Investigator on the McMurdo Dry Valleys Long Term Ecological Research program, one of the two Antarctic LTER sites funded by the National Science Foundation. He is a U.S. representative on the SCAR Geosciences Standing Scientific Group, and currently the Chief Officer this Group. He is also a former Director of the Byrd Polar Research Center at OSU. He is an associate editor for CHEMICAL GEOLOGY and POLAR SCIENCE.
