Dr. Siddhartha pursued his doctoral research at the Indian Institute of Technology Indore (IIT Indore), where he earned a Ph.D. in Metallurgical Engineering and Materials Science. He received his Bachelor of Engineering (B.E.) in Electronics and Communication from R.G.P.V, Bhopal followed by a Master of Technology (M.Tech) in Nanotechnology from the School of Nanotechnology, UIT-RGPV, Bhopal. At IIT Indore, his work focused on synthesis of Ga2O3 nanostructures and thin films for application in thin film electronic devices, specifically memristors. His work also contributed for optimizing parameters for crack-free thin film growth using the spin coating method on different substrates. He has published various research articles and several book chapters.
After completing Ph.D., Dr. Siddhartha joined the Centre for Excellence in Nanoelectronics (CEN) at Electrical Engineering department in Indian Institute of Technology Bombay (IIT Bombay) as a Project Research Scientist. Here, he led the development of silicon carbide (SiC) device technology for fabricating 2 and 3 terminal device such as diodes and MOSFETs applicable in next-generation electric vehicles (EVs). He was involved with projects related to Ga2O3 device technology also. Dr. Siddhartha expertise extends to device fabrication and characterization tools, including thin film deposition tools (ALD, CVD), metal deposition techniques (Sputter, E beam Evaporator), photolithography, dry and wet etching.
