- I am a paleoclimatologist. I am trained in geochemical applications within the broad discipline of earth sciences. My research focuses on reconstructing and assessing the impact of climate variability on human societies, especially in semi-arid regions over the past 1000 years and (b) corals as environmental archives. I combine paleoclimatic methods with historical, archeological studies and climate models to address questions of how climate variability impacts availability and access to resources in arid and semi-arid regions. My marine studies focus exclusively on understanding how corals trap particulate matters and what does a record of particulate matter in coral cores tell us about the response of reefs to coastal water pollution.
