Profile:

I’m a NERC CENTA PhD student (2015-present). My project involves reconstructing the Indian Summer Monsoon’s response to abrupt climate change during Marine Isotope Stage 5.

Research:
My research involves using marine sediments recovered from the Bay of Bengal, the core convective region of the Indian Summer Monsoon, from IODP Exp. 353. The Indian Monsoon affects some of Earth’s most densely populated areas therefore, it is important to have a comprehensive understanding of the monsoon and how it responds to climate forcing. Reconstructing past monsoon behaviour can allow us to tease out how sensitive its response is to forcing such as changes in ice volume or greenhouse gases. Termination II (~135, 000 years ago) and the Last Interglacial Period (~125,000 years ago) provide a useful case study to investigate the monsoon response to warming.

I am using a multi-proxy approach that includes bulk sediment elemental composition and geochemical tracers in foraminifera to reconstruct changes in Indian Summer Monsoon induced runoff and precipitation changes from 140,000-70,000 years ago.
