Preethi Raghavan

I am a PhD student in Computer Science and Engineering at the Ohio State University. I am co-advised by Dr. Eric Fosler-Lussier and Dr. Albert Lai. I am part of the CSE Speech and Language Technologies (SLaTe) Lab and my research interests include natural language processing and information retreival.

I received a Masters in Computer Science and Engineering from The Ohio State University in 2009.
