About Me

I am an Assistant Professor in the Department of Computer Science at Rutgers University. I am a member of the Computational Biomedicine Imaging and Modeling Center. I completed my Ph.D. in Computer Science from Stanford University, under the supervision of Ronald Fedkiw, followed by postdoctoral studies at the University of Wisconsin-Madison, where I was advised by Eftychios Sifakis. I have a B. Tech. in Computer Science and Engineering from the Indian Institute of Technology Kharagpur.

I am interested in the areas of computer graphics, high-performance computing, computational biomechanics, and robotics. Specifically, I develop numerical methods in computational physics that can benefit from the compute power available on modern workstations, by leveraging accelerations both at the algorithmic and systems level. Recently, we have started applying these techniques to analyze musculoskeletal motion of the human body, under various normal and pathological configurations, as well as for learning unknown physical parameters for applications in robotics. My long term goal is to enable the design of next generation algorithms that can facilitate interdisciplinary collaboration with researchers in engineering and medicine for understanding phenomena that are intractable by current means. Outside of work, I enjoy running, rock climbing, hiking, watching movies, and playing piano.

At Rutgers, I direct the Laboratory for Interactive Virtual Environments (LIVE). If you are a prospective graduate student interested in joining our lab, please apply to the Ph.D. program in Computer Science at Rutgers University, and mention my name in your application. If you would like to apply for a postdoc position, please email me your CV directly.
