Hello! I'm Prakhar.

"I am the master of my fate,
I am the captain of my soul." -- Henley

I'm a fourth year doctoral candidate in Mechanical Engineering department at University at Buffalo (SUNY), NY. Currently, I'm a research assistant at MAD Lab, supervised by Dr. Rahul Rai. I have spent two semesters (Summer and Fall 2015) as an Intern at Xerox PARC in Palo Alto, CA, and one semester (Summer 2016) as a Research Intern at Siemens Corporate Technology in Princeton, NJ. I received my Bachelors degree in Mechanical Engineering from IIT Kanpur, India in 2011.

My current research interests include computational geometry, mesh processing, machine learning, computer vision, and probabilistic graphical models. Here is a link to my CV.

The best way to contact me is by email: prakharj@buffalo.edu
