Guest PhD


Subash Gireesan completed his Master’s degree at the Institute of Chemical Technology, Mumbai. During his Masters, he worked on modelling the chemical transformations happening inside a cavitating bubble, with the aim of maximizing the production of oxidizing radicals. Currently he is pursuing is PhD at group of M2N, and the project is a part of the Shell-NWO Computational Sciences in Energy Research (CSER) PhD program. His work focuses on understanding thermal transport in semiconductor nanowires, for the application in thermoelectrics. He succesfully defended his PhD thesisCongratulations to Dr. Subash Gireesan, who successfully defended his PhD thesis “Modeling Novel Thermal Transport Phenomena in Semiconductor Nanowires” April, 2021.

Subash is now working as a data scientist at computational center, at Shell, Bangalore.
