I am a Malone Postdoc Fellow in the Department of Computer Science at Johns Hopkins University, affiliated with the Malone Center for Engineering in Healthcare and the Center for Language and Speech Processing. I am mentored by Mark Dredze, Ziang Xiao, and Chien-Ming Huang. My research lies at the intersection of Human-Computer Interaction, AI, and Software Engineering. [more]
I design, build, and evaluate human-AI collaborative systems for tasks requiring intensive human judgment, especially where no or little ground truth exists (e.g., qualitative analysis, code comprehension, code review and auditing, subjective data annotation). As AI takes on increasingly autonomous roles in these workflows, I study how humans can effectively collaborate with AI to achieve better outcomes, and how they can evaluate and oversee AI systems to ensure trustworthy results.
My long-term goal is to ensure effective and trustworthy human-AI collaboration, especially for tasks where human judgment matters most.
I mainly pursue two complementary directions:
Bring AI to Humans
Integrating AI into human workflows to help people perform subjective tasks more effectively and confidently.
Bring Humans to AI
Bringing humans to AI to ensure better supervision and evaluation of increasingly autonomous AI systems, so that these systems are more trustworthy and responsible.
