I am working as an Assistant Professor in the Department of Computer Science and Engineering, at Indian Institute of Technology Jodhpur, Rajasthan, India. I have completed my Ph.D. from the Visualization and Perception Lab, Indian Institute of Technology Madras under the guidance of Prof. Sukhendu Das on Content Based Video Retreival (CBVR).

My current research interests span the broader area of Computer Vision, and applied Machine Learning. I am also actively engaged with the interdisciplinary research platform on Digital Humanities and working in the areas of Migration, Cultural Heritage, Game Studies. I am very much interested in interdisciplinary work, and shall be happy to advise undergraduate, postgraduate, and doctoral students who wants work in the areas like Image Analytics, Digital Humanities, Computer Graphics, AR-VR, Industry 4.0, Digital Healthcare.

I was an associate with Tata Consultancy Services (TCS) Ltd. based out of Chennai, India. My primary responsibility was of a module lead of a leading US based telecom client of TCS. On the experience front, I have worked in both, development and quality assurance roles.
