Abhilasha Ravichander

I am a PhD student in the Language Technologies Institute at Carnegie Mellon University. I am advised by Eduard Hovy and Norman Sadeh.

I received my bachelor's degree from P.E.S Institute of Technology, Bangalore in 2015. During the summer of 2014, I was a visiting student at the Institute of Mathematical Sciences.

My research interests lie broadly in robustly capturing semantic meaning in text. For more about my work, please see my publications list.
