Theja Tulabandhula, Ph.D.

Bio

• I am currently an Assistant Professor at the University of Illinois Chicago. Here,
  • I work on research themes related to machine learning and sequential decision making (see below).
  • I teach Advanced Predictive Models (last offered in Spring 2017) and Statistical Models and Methods (Fall 2017).
• I was a Research Scientist at Xerox Research (Machine Learning and Statistics, Data Analytics Lab) from 2014-2016.
• I received a PhD in Electrical Engineering and Computer Science from MIT, and was advised by Cynthia Rudin. While there, I was also a Fulbright Science and Technology Scholar.
• Before that, I was an undergrad at IIT Kharagpur, where I was also awarded the Prime Minister's Gold Medal.

Research Interests

I am broadly interested in artificial intelligence, operations research and their applications to multiple scientific and business domains. I have worked on theoretical and empirical aspects of: (a) supervised learning in the presence of operational information, (b) transportation problems including scheduling and fair ride-sharing, (c) assortment optimization, and (d) several online and reinforcement learning problems.
