Research Interests

Paleoclimate reconstructions, geochemistry, stable isotopes, speleothems

My research is part of the TwoRains ERC-funded project headed by Dr. Cameron Petrie at the Division of Archaeology. 

My contribution to the TwoRains project consists of paleoclimatic research covering the period of the Indus Civilization (4600 - 3900 years BP) in northwestern India. Specifically I am looking at changes in precipitation that coincided with societal changes during and after the Mature Harappan urban phase. I am using proxies from a broad latitudinal gradient to investigate the timing and extent of the weakening of the Indian Summer Monsoon, which coincides with Indus de-urbanization. My research is based on geochemical analysis of marine foraminifera in the Arabian Sea, paleolake sediments close to populous Harappan centers, as well as speleothems in Himalayan caves.      

Research Supervision

My research is supervised by Professor David Hodell (Earth Sciences) and Dr. Cameron Petrie (Archaeology)
