Sayak Patra
PhD Student
Thesis Title: Estimating Aerosol Physicochemical Mixing State and Its Effects on Select Climate Variables over Central India: Field Measurements and Machine Learning.
Email: sayak23@iiserb.ac.in
Research Interests: My research interest mainly aims to investigate the aerosol chemical mixing state and its effects on radiative transfer and precipitation over central India. I use near-real-time field measurements, WRF-Chem model atmospheric output data product and machine learning techniques (PartMC and XGBoost algorithm) to estimate the aerosol chemical mixing state, past variability (2000 to 2020) of aerosol chemical mixing and its impact on climate change. Apart from that, I am an amateur astronomer. My hobbies include making telescopes, reading books (specially Sci-fi), playing football and Hindustani classical music (specially Tabla).
