Principal Investigator 

Anurag Goyal 

Assistant Professor, Mechanical Engineering, IIT Delhi

Anurag joined as an assistant professor in the Department of Mechanical Engineering at IIT Delhi in June 2021. Prior to joining IITD, he was a researcher in the Building Energy Sciences group at the National Renewable Energy Laboratory (NREL) (2019-2021). His research at NREL focused on the design and characterization of thermal energy storage components for buildings. During his PhD, he worked with Dr. Srinivas Garimella in the Sustainable Thermal Systems Laboratory (STSL) at Georgia Tech (2012-18). His graduate research focused on understanding the dynamics and developing control systems for small-capacity, heat-driven absorption cooling systems. He completed his undergraduate in mechanical engineering from IIT Delhi (2008-12).

Ritwik Kumar

PhD Student (July 2023 - Present)

Project: Thermal energy storage systems for buildings 

Ritwik completed his B.Tech. in Mechanical Engineering from Tezpur University, where his final year project was to study how used cooking oil blends impact the performance of a diesel engine. He completed his Master's in Thermal Engineering from NIT Durgapur in 2021. His M.Tech. research focused on using CFD to analyze the flow patterns and heat transfer characteristics around a pair of anti-symmetrically heated cylinders within a closed cavity. 

Ritwik plays tennis in his spare time and has a fondness for stop-motion animated movies.
