My research primarily focuses on using remote sensing and Geographic Information Systems (GIS) for physical and spatial environmental geography studies. More recently, I am focusing on the use of remote sensing and spatial analysis to examine land use/land cover, human-ecosystem interactions and air pollution episodes over the continental US and South/Southeast Asia. My expertise is also in fire ecology and biogeochemistry studies. Formerly, I worked as a Research Scientist (2005-2009) and Postdoctoral researcher (2001-2004) at the Agroecosystem management Program, The Ohio State University. Specifically, I worked on agriculture, soils and, ecosystem health projects involving remote sensing and GIS components at the OSU. Prior to coming to the US (2001), I gained my Ph.D. (1997-2000) in remote sensing topics while working at the Indian Space Research Organization (ISRO), National Remote Sensing Center (NRSC), India. My Ph.D. focused on characterizing biodiversity and forest cover dynamics in tropical forests using remote sensing techniques and ecosystem modeling under the guidance of dual supervisors, one Physicist (Remote sensing aspects) and another forest ecologist. In the US, I served as a PI and Co-I on diverse projects funded by NASA, USDA, NSF, etc., all involving remote sensing component. My research had been highly interdisciplinary and the publications are in carbon science, biomass burning/greenhouse gas emissions, agroecosystem studies, water resources, land-atmospheric interactions, biodiversity studies, spatial statistics, multi-criteria algorithms, and ecosystem sustainability. I strongly believe that hard work is the key to success. I am married to Anuradha Vadrevu and have two kids who keep us busy.

As of July 2016, I joined a civil service job at NASA Marshall Space Flight Center (MSFC), as Earth Science Remote Sensing Scientist, Earth Science Office, Huntsville, Alabama. Also, I am currently serving as Deputy Program Manager for the NASA Land Cover / Land Use Change (LCLUC) program. I am continuing as an Adjunct Associate Professor at the University of Maryland College Park, US.

Teaching Philosophy
My teaching practices strive to engage student’s interest and help them gain knowledge and skills in such a way that they are able to apply what they learned not just in examinations, but outside the classroom as well. In essence, I believe that the teaching of a particular course should not only be focused on learning the required course material, but also emphasize on directing the students to think independently and develop skills that are required to succeed in the competitive world. I am still exploring effective teaching strategies for communicating complex issues and ideas to diverse group of students with different educational background.

My expertise is in Remote Sensing and GIS related research and applications. My research philosophy is to: a). Understand human-earth interactions relating to vegetation, biogeochemical cycling of nutrients, land use/cover changes and greenhouse gas emissions using ground based information as well as Remote sensing and geographical information systems (GIS); b). Consider natural resource problems as part of a complex process-response system involving human interactions; implement studies that compare processes over a range of spatial scales by synthesizing data such as land use changes, vegetation, soils, hydrology, demography and socioeconomic data; c). Establish and teach methodological approaches often using Remote sensing and GIS, biophysical methods in spatial geography, climatology, and ecology for addressing coupled human-earth interactions.
