Biography

Dr. Vishnu R Unni is a Assistant Professor in the Department of MAE. Prior to joining IITH, Dr. Vishnu worked as a research associate at the Law Lab, Princeton University, USA and a post-doctoral scholar at Saha Lab, University of California San Diego, USA. He received his Ph.D in 2017 from the Dept. of Aerospace Engineering, Indian Institute of Technology, Madras. His research is on reactive fluid dynamics, particularly focusing on the characterization and control of complex self-organised dynamics of turbulent reactive flows. He performs both experimental and theoretical investigations to unravel the universal behaviours that reactive/non-reactive flow systems exhibit, and further develops data driven models that capture phase transitions in such systems.
