Preethi Jyothi

Assistant Professor
Department of Computer Science and Engineering, IIT Bombay

e-mail: #pjyothi# at cse.iitb.ac.in (delete leading and trailing #'s)
office: room 221, new CSE bldg


About me: I joined the department in September 2016. Prior to that, I was a Beckman Postdoctoral Fellow at the University of Illinois at Urbana-Champaign. I obtained my Ph.D. from the CSE Department at The Ohio State University in 2013. My research interests are broadly in the areas of automatic speech recognition and machine learning as applied to speech.

Student projects: I am currently not offering any internship positions or research projects to students outside IIT Bombay. Apologies for not being able to individually respond to the numerous student emails enquiring about this.
