Nakul Gopalan

I am a postdoctoral researcher in the CORE Robotics Lab with Prof. Matthew Gombolay at Georgia Tech. I completed my PhD at Brown University's Computer Science department in 2019. Previously I was a graduate student in Prof. Stefanie Tellex's H2R lab at Brown. My research interests lie at the intersection of language grounding and robot learning. I am interested in algorithms and methods that allow robots to be trained by leveraging demonstrations and natural language descriptions. Such learning would improve the usability of robots within homes and offices. My other research interests are in hierarchical reinforcement learning and planning.

I am teaching Machine Learning at GaTech in Spring 2021.

I have been a grad TA for the AI course at Brown in Spring and Fall 2017.

I have also worked on outreach efforts from Brown at the local schools in Rhode Island under Ignite CS. I am interested in computer science education efforts in school and college classrooms. I have participated in various teaching fundamental courses at Brown's Sheridan Center for Teaching and Learning.
