Delighted to announce:

  • I'll be joining the Department of Computer Science at UMASS, Lowell as an Assistant Professor in Jan 2020. I'm looking forward to working with excellent people who are passionate about human language and its role in other fields such as Medicine.
  • I have a few openings for motivated PhD students to start in Jan/Sep 2020; please get in touch through email (don't forget to attach a CV).

User Generated Content, which can range from social media discussions to product reviews to private physician notes, present naturally occurring data that can be used to develop large-scale Machine Learning algorithms for effective processing of human language. My general research interest is in developing linguistically-aware and cognitively-motivated Machine Learning algorithms for problems that arise in the context of Biomedical Informatics with a specific focus on Undiagnosed Diseases.

I'm part of Zaklab and work with Dr. Isaac Kohane and Dr. Andrew Beam on the above problems. Please read more about my research here.
