I am a PhD candidate at University of Michigan. My research aims to leverage human computation and machine intelligence to effectively solve complex tasks that require domain expertise, such as software development. I study problems that users face during collaboration with existing tools and methods, and build computational systems to assist users via efficient collaboration and hybrid crowd-machine workflow. My advisor is Dr. Steve Oney.
