I am a fifth year PhD student at the Language Technologies Institute at CMU. My advisers are Professor William W. Cohen and Professor Ruslan Salakhutdinov. In 2013 I graduated from IIT Kanpur with a Bachelor and Masters in Technology, Electrical Engineering. At IIT Kanpur I worked with Professor Amitabha Mukerjee. Prior to joining CMU I worked at Qualcomm Research in San Diego, USA.
