Gustavo Marques Hobold

I am a Ph.D. student in Mechanical Engineering at the Massachusetts Institute of Technology, working with Prof. Betar Gallant at the Energy and Gas Conversion Laboratory. Previous to coming here, I graduated with Master’s and Engineer’s degrees from the Federal University of Santa Catarina, Brazil, working with Prof. Alexandre K. da Silva.

My main research interest is in discovering safer battery chemistries, and in understanding the fundamental chemical and electrochemical mechanisms that enable safe, energy- and power-dense energy storage system. In addition to using existing experimental techniques, I am developing novel ways to probe electrochemical and chemical reactions at very small scales.

I am also interested in supercritical thermal energy storage and in using machine learning to enable research in complex phenomena, such as multiphase flow and phase-change heat transfer.
