Curriculum Vitae

Shantanu has a Ph.D. from Carnegie Mellon University where he used numerical models and laboratory experiments to understand the atmospheric formation of organic aerosols from combustion sources such as cars, trucks, aircraft and wildfires. He worked as a post-doctoral scholar at the University of California, Davis where he was funded by the California Air Resources Board to improve the treatment of particulate matter in air quality models used for regulatory purposes. Shantanu’s research interests lie at the intersection of energy and the environment. By leveraging laboratory experiments and regional/global air quality models, he intends to study the atmospheric evolution and properties of air pollutants arising from energy systems, all in the interest of addressing future energy and environmental policy. Shantanu hails from the suburbs of Mumbai, India. He is married to Poorva (an electrical engineer) and is enjoying parenthood with Vedant and Vikram. In his spare time, he likes to run, bike, sip tea, and play the bansuri (bamboo flute).
