About

Dr. Raj’s research interests include Deep Learning, signal and image processing, and FPGA implementations. To his credit, he has published more 90 peer reviewed publications, 4 book chapters and has edited a book. He has rich experience in developing imaging algorithms and implementing those designs on reconfigurable hardware. As a Principal/Co-Principal investigator he has received funds from various national and international organizations, such as the Department of Science and Technology India, Guangdong Provincial funds and the Indo-Russian Bilateral funds. Currently he is an Associate Editor of IEEE Access and also serves as the reviewer for many peer reviewed journals including Pattern Recognition, IEEE Transaction on VLSI, Computation Intelligence etc.  

With over 10 years, Dr. Raj has handled lectures for both mandatory and elective courses for Electronics Engineering Undergraduates: handled Digital Signal/ Image Processing, Digital Electronics, Embedded and FPGA based System Design, Robotics and Automation, Control Systems and RTOS; For Masters: delivered lectures on Statistical Signal Processing, VLSI signal processing; and Image Processing and Feature Extraction.
