Bio

Parag Chitnis joined the Department of Bioengineering at George Mason University in Fall of 2014. He also is an affiliate faculty at the Krasnow Institute of Advanced Study. He received his Ph.D. in Mechanical Engineering from Boston University in 2007 under the supervision of Prof. Robin Cleveland. From 2007-2008, he was post-doctoral research fellow in the same department for Prof. Ronald Roy. After completing his post-doctoral training, he joined Riverside Research Institute as a Scientist, where he was a Principal Investigator pursuing research in medical ultrasonics and photoacoustics until 2014. He received the Riverside Research’s Ralph J. Mastrandrea Award for Outstanding Excellence in 2011.
