I am a Postdoctoral Fellow at the University of Toronto, working with Tovi Grossman. My research theme is On-Demand Programming Assistance. In particular, my research in human-computer interaction (HCI) studies challenges that computer programmers at all levels of expertise face when using existing tools and methods to seek support. It combines human and machine computation to create programming support systems that can effectively and scalably assist programmers when needed. The systems I create address challenges including providing personalized help in nearly real time, providing feedback to learners at scale, making communication more effective, better using human effort to progressively automate machine, and coordinating teams to more efficiently collaborate, which neither computers nor humans can effectively solve alone. To make these systems possible, my research explores how to design workflows and interfaces that can effectively coordinate and scale the collective effort of experts, non-experts, and machines.
