I have always been curious about natural and human-developed worlds. That has motivated me to "push the envelope" on natural climate variability and its impacts on water, food, and energy. But, I am also acutely aware that socieo-economic and political systems don't always work according to principles of scientific reasoning. That is where the grand challenges of ensuring food-energy-water securities to increasing population equitably are.

Biography

Dr. Vikram Mehta earned M.Sc. in Physics from Gujarat University, India in 1977; Post-graduate Diploma in Space Sciences and Their Applications from Gujarat University in 1979; and was an Indian Space Research Organization (ISRO) Research Fellow at Space Applications Centre, ISRO, Ahmedabad, India from 1979 to 1982 working on Microwave Remote Sensing.  He then studied Upper Atmosphere Physics at the University of Saskatchewan in Saskatoon, Canada from 1982 to 1984, earning a Post-Graduate Diploma in Physics.  A strong interest in more applications-oriented scientific research led him to the Department of Meteorology at the Florida State University in Tallahassee, Florida, U.S.A. where he earned M.S. degree in 1986 and Ph.D. degree in Meteorology in 1990.  Vikram was then a research scientist for over 12 years in NASA-Goddard Space Flight Center, further specializing in identification of ocean-atmosphere interactions that give rise to decadal climate variability (DCV). Strongly motivated to use climate science for societal benefits, Vikram founded the Center for Research on the Changing Earth System (CRCES), a non-profit, scientific research organization in Columbia, Maryland, U.S.A. in 2002, with initial funding from NASA.  Currently, he is the President and Executive Director of CRCES.  In addition to NASA, CRCES is also funded by grants from NOAA, NSF, USDA, and USGS for research and other activities on DCV and its societal impacts.  Vikram’s major research interests are understanding and prediction of DCV; assessment of DCV impacts on water resources, agriculture, public health, and the economy; and climate and public policy.  Vikram has published over 150 research papers and Conference/Workshop presentations.

Personal Interests

    Among major hobbies are flying a single-engine airplane, reading, and listening to Indian and Western classical music.
