I am currently a Ph.D. candidate in Environmental Engineering at Vanderbilt University, where I am a Graduate Fellow at the Vanderbilt Institute for Energy and Environment and a member of an NSF-funded trans-institutional interdisciplinary project exploring agricultural adaptation to changing climate in Sri Lanka.
My research integrates survey data, geospatial data, remotely-sensed imagery, and qualitative data to identify the factors that moderate the effects of meteorological drought on surface water irrigation systems across space and time. I am particularly interested in using quantitative tools to explore political ecological and distributional dimensions of climate change and adaptation.
