I am a Computer Science Ph.D. student at Portland State University, advised by Prof. Atul Ingle. My research interests include 3D computer vision, computational Imaging, and Design of Synthetic dataset generation pipelines. Previously, I was a Senior Research Fellow at the Computer Vision Graphics and Imaging Lab of IIT Gandhinagar, supervised by Prof. Shanmuganathan Raman. Before that I worked at the Autonomous Robots and Multi-robot Systems (ARMS) Lab of the Indian Institute of Technology Bombay as a Research Associate supervised by Prof. Leena Vachhani and Prof. Abhishek Gupta. |
