Biography
Karthick was born in Tamil Nadu, India. Currently he is pursuing his PhD at Centre for Advanced Photonics and Electronics (CAPE), Electrical Engineering division under the supervision of Prof.Florin Udrea. His research focusses on developing reliable normally off p-GaN HEMT's for power applications. He is a Dr.Manmohan Singh Scholar (St.John's scholar) and member of St. John's college. Prior to his doctoral studies he has worked as Technology Development Engineer at TSMC, Taiwan developing Si based Analog/RF/power technologies.
He received his master's degree in Electrical Engineering specializing in Microelectronics & VLSI from Indian Institute of Technology - Bombay (IIT-B) and Bachelor's degree in Electrical Engineering from Anna University - Chennai. During his post graduate studies he has worked as research engineer intern at Solar Energy Research Institute of Singapore (SERIS), NUS, Singapore.
He has filed 5 US patents (3 as lead inventor) and penned 8 research articles in the field of CMOS Semiconductor devices, c-Si solar cells.
