Post-doctoral Researchers

Sriram Krishnamoorthy 

Sriram Krishnamoorthy is currently a post-doctoral researcher at The Ohio State University. He received his bachelors degree in Electrical Engineering and Physics from Birla Institute of Technology & Science (BITS), Pilani, India, in 2009. He received his doctoral degree from the Electrical and Computer Engineering department at The Ohio State University in August 2014 (Advisor: Prof. Siddharth Rajan). His doctoral work focused on demonstration of state-of-the-art Gallium Nitride-based interband tunnel junctions for optoelectronic applications. His research interests include electronic/optoelectronic devices based on MBE-grown wide band gap semiconductors (Gallium Oxide, III- nitrides) and Van der Waals epitaxy/ devices based on 2D-layered materials. He is a recipient of the the Ohio State University Presidential Fellowship Award (2014).
