Early Life and Education
Dr. Sourav Roy began his academic journey in 2003 when he enrolled in the B.Tech programme in Electronics and Communication Engineering at St. Thomas' College of Engineering and Technology, Kolkata, completing his graduation in 2007.
After gaining industry experience, he pursued his M.Tech in Microelectronics and VLSI Design at Techno India, Salt Lake, Kolkata (2010) — graduating first at the university level with a perfect grade of 10 out of 10 in all subjects. Under the mentorship of Dr. Somenath Chatterjee — who had industrial experience at Texas Instruments, USA and research experience at IIT Kharagpur and the University of Houston — he developed a deep passion for semiconductor research.
His academic excellence led to admission at Chang Gung University (CGU), Taiwan in 2012 — with a full scholarship and tuition waiver under a project funded by the Ministry of Science and Technology, Taiwan, in collaboration with industry leaders ITRI and TSMC. He completed his Ph.D. in Electronics Engineering (2017) under the supervision of Dr. Siddheswar Maikap, focusing on Metal Oxide-based Resistive Switching Memory for Biosensor Applications.
Career
Industry Experience (2007–2010)
After completing his B.Tech, Dr. Roy joined Midas Autosoft Pvt. Ltd., Pune as a Service Engineer (2007–2008) — commissioning weighing and batching automation equipment for Ferro Alloy Industries across Jharkhand, West Bengal and Odisha. He was subsequently promoted to managerial level. He later joined Bentron Power as a PCB Design Engineer (2008–2010), designing printed circuit boards for Indian Railways' communication systems — including GPS clocks, gateway telephones and control room communication equipment.
Doctoral Research — Chang Gung University, Taiwan (2012–2017)
Dr. Roy's Ph.D. at Chang Gung University, Taiwan — supported by a full scholarship — was a transformative period. His research on metal oxide-based resistive switching memory for biosensors resulted in numerous high-impact publications in journals including Scientific Reports, Journal of Alloys and Compounds, Applied Surface Science and Nano Micro Letter.
Academic Career — Ashoka Institute of Engineering and Technology, Hyderabad (2017–2018)
After receiving his doctoral degree in August 2017, Dr. Roy joined Ashoka Institute of Engineering and Technology, Hyderabad as Assistant Professor and PG Coordinator and briefly served as Associate Head of Department, contributing to the institution's NAAC accreditation process.
Postdoctoral Research — Xi'an Jiaotong University, China (2018–2020)
In October 2018, Dr. Roy joined the State Key Laboratory for Electronics Materials at Xi'an Jiaotong University, China as a Postdoctoral Research Fellow under Professor Dr. Gang Niu. His research focused on synaptic behaviour in hafnium oxide-based ReRAM through controlled aluminium doping and on flexible TiO₂-based RRAM for neuromorphic applications.
Christ University, Bangalore (2021–Present)
In 2021, Dr. Roy joined Christ University, Kengeri Campus, Bangalore as Assistant Professor in the Department of Electronics and Communication Engineering — a role he continues to hold with distinction. At Christ University, he has:
- Co-founded the C.H.R.I.S.T Lab (Coatings and Heterostructure Research in Innovative Sensors and Thin Films) — a dedicated lab for nanoparticle ink synthesis and noninvasive sensor design, supported by university seed grants
- Served as a core member of the RF & Microwave Center and the Academic Payload Development Center
