Nakul Gopalan

I am a PhD student in Stefanie Tellex's H2R lab at Brown. I am interested in the problems of grounding language to tasks. My other interestes are hierarchical learning and planning. My research goals are to have robots at homes that we can teach with language and demonstrations.

Teaching

I have been a grad TA for the AI course at Brown in Spring and Fall 2017. I work on outreach efforts from Brown at the local schools in Rhode Island under Ignite CS. I also learn teaching fundamentals at Brown's Sherdian center.
