Hi, I’m Arnab!

I am a Postdoctoral Fellow at The University of New Mexico, Albuquerque. My current advisors are Prof. Francesca Cavallo at UNM and Dr. Danhong Huang at Sandia National Labs. Prior to this, I completed my Ph.D. in Electrical and Computer Engineering from University of Massachusetts Amherst NanoEnergy & Thermophysics lab under the supervision of Prof. Zlatan Aksamija.

Currently, I am working on understanding the electrical and thermal transport properties in a CVD-grown graphene on technologically relevant substrates, such as Si and Ge. Also, I am working with Dr. Huang to develop computational models based on first-principles to capture non-thermal phonon dynamics interacting with driven conduction electrons.
During my stay at UMass Amherst, I have developed scientific computational models based on first-principles Density Functional Theory calculations for understanding charge and heat flow in two-dimensional (2D) van der Waals (vdW) semiconductors, including graphene, transition metal dichalcogenides and beyond-graphene materials, and in their heterostructures. Beyond developing electro-thermal simulations for 2D nanoelectronic devices, my research interests also encompass developing data-accelerated multiphysics device models to improve our understanding of complex material systems.
