SITANGSHU BHATTACHARYA


Sitangshu Bhattacharya obtained his B.Sc. degree in Physics and M.Sc. Degree in Electronic Science from The University of Calcutta, India in the year 2001 and 2003 respectively. He received his Ph.D degree in 2009 from Jadavpur University, India. During his Ph.D-ship, he worked on the computational aspects of electronic properties like Einstein relation, photoemission, etc. of emerging materials and devices. During the tenure 2008-2013, he was associated as a post-doc with Professor Santanu Mahapatra at the Department of Electronic Systems Engineering, Indian Institute of Science, Bangalore, India, where he worked on the electronic and thermal Landauer conductance of carbon nanotubes and graphene. He was also associated as a regular faculty member in the Department of Electrical Engineering, Shiv Nadar University during the period 2013-2014.

Dr. Bhattacharya joined the Department of Electronics and Communication Engineering, IIIT-Allahabad on June, 2014 as an Assistant Professor, where his current research interest lies in the analytical and computationl modelling of electro-thermal properties of nanoscale materials and devices for power boosters. He founded the Nanoscale Electro-thermal Laboratory @ IIIT-A with a strong focus, as part of materials, on carbon based materials like graphene and nanotubes together with other materials like dichalcogenides, complex materials, III-V and strongly correlated materials. As part of devices, his areas of interest are on molecular devices and their noise and RF analyses and first principle based modelling of thermoelectric devices and circuits and solar cells. He is currently the recipient of the prestigious INSPIRE Faculty Award, 2013 by DST, Govt. of India with several international journal publications.
