I am an associate professor at the University of New Hampshire with a joint appointment in the Department of Physics and Space Science Center of EOS.

I graduated from the Pennsylvania State University with a Ph.D. degree in Electrical Engineering in 2006. I continued my study there as an NSF CEDAR Postdoc Fellow until I started as an assistant professor of the Department of Physics and Space Sciences at Florida Institute of Technology in Spring 2008. I was promoted to associate professor in 2012. I moved to UNH in 2016.

I received A. J. Ferraro Award for Excellence in Ph.D. Research from Penn State in 2005, Young Scientist Award from International Union of Radio Science in 2008, and Faculty Excellence Award in Research from Florida Tech in 2016. I am a recipient of NSF CAREER Award.
