Ramji Singh is a Post Doctoral Research Scholar in the Department of Electrical Engineering at Arizona State University being supervised by Dr. Marco Saraniti. Ramji Singh obtained his PhD from University of Illinois at Chicago, USA in 2022. His PhD work focused on Electron – Phonon interactions in emerging semiconductors and their heterostructures for power electronics (charge and heat transport) and quantum applications. For ULTRA, he is working on Cellular Monte Carlo framework for electro – thermal simulations of semiconductor devices and developing software for phonon effects for computational heat modeling.
