Dalia Kirschbaum - President

Chief of the Hydrological Sciences Laboratory, NASA Goddard Space Flight Center, Greenbelt, Maryland. 

Dalia Kirschbaum is the Chief of the Hydrological Sciences Laboratory at NASA Goddard Space Flight Center, Greenbelt, MD. In this role, she leads an interdisciplinary Earth system science lab at NASA to conduct large-scale hydrological science research using data from NASA’s satellites, land surface models, and fieldwork. Dr. Kirschbaum’s work focuses on rainfall-triggered landslide modeling, monitoring and mapping using remotely sensed information to conduct landslide hazard and risk studies at multiple spatial and temporal scales. Dr. Kirschbaum is a Disaster Response Coordinator for the agency, working with other NASA centers as well as domestic and international partners to bring satellite data and products to bear during natural hazard events. Dr. Kirschbaum received her M.S. and Ph.D. in Earth and Environmental Sciences from Columbia University and her A.B. in Geosciences from Princeton University.

Dr Kirschbaum has been an AGU member since 2004 and has actively engaged with AGU over the past 15 years, first serving on the Program Committee for 3 years for the Natural Hazards section and then participating as an executive committee member for the Natural Hazards and the Remote Sensing-Hydrology Focus Groups. She has organized landslide sessions each year as well as Union and Hydrology-focused sessions and is interested in expanding the Natural Hazard Sections engagement with Diversity and Inclusion activities including the Hazard Equity Working Group (HEWG), which was started in 2020. 


 Guido Cervone - President-Elect 

Professor of Geography, Meteorology and Atmospheric Science, and an Associate Director of the Institute for Computation and Data Sciences at the Pennsylvania State University

Guido Cervone is a Professor of Geography, Meteorology and Atmospheric Science, and an Associate Director of the Institute for Computation and Data Sciences at the Pennsylvania State University. He is also an Affiliate Scientist with the National Center for Atmospheric Research (NCAR) and an Adjunct Professor at the Instituto Sant’ Anna, Italy.  He received a B.S. (1998) at the Catholic University of America, an M.S. (2000) in Computer Science at the George Mason University, and Ph.D. in Computational Science and Informatics (2005) at the George Mason University.  He has been an AGU member since 2004.

Guido's research sits at the intersection of geospatial science, atmospheric science and computer science.  He focuses on the development of computational algorithms for the analysis of remote sensing and numerical modeling data associated with extreme events, hazards and renewable energy. The two main themes of his research are the study of uncertainty associated with probabilistic forecasts for rare and extreme events; and atmospheric characterization using hyper-spectral remote sensing scenes.  

Bill Fry - Secretary




Seth Stein - Past President

Deering Professor of Geological Sciences, Northwestern University, Evanston, Ill.

Volunteer experience includes AGU duties serving as JGR editor, Seismology program chair for the Fall Meeting, Seismology and Geodesy section committees for recommending AGU Fellows, and chairing the Bucher Medal and Excellence in Geophysical Education Award committees. I have served on medal committees for the EGU and GSA, panels for NSF, NASA, the European Science Foundation, German Science Foundation, and European Research Council, and on advisory committees for departments in the U.S. and abroad. I have been an AGU member since 1976.

Much of my research explores how earthquakes result from tectonic processes at the boundaries of plates and within them, and how limitations in our understanding of these processes affect our ability to forecast earthquake hazards. Because similar challenges arise for other natural hazards, I am interested in general questions of estimating uncertainties in hazard forecasts, assessing how well they work, and developing mitigation strategies that make societal and economic sense, given limited resources and limited knowledge about what the earth will do.
