I am currently a Malone Postdoc Fellow in Malone Center for Engineering in Healthcare & Department Computer Science at The Johns Hopkins University, starting March 2025. I am mentored by an interdisciplinary team of NLP and HCI, including Mark Dredze, Ziang Xiao, and Chien-Ming Huang. My research interests include Human-AI Collaboration, AI for Social Science and AI for Software Engineering. More specifically, my research focuses on building, theorizing and evaluating AI innovative software/tools, particularly in qualitative analysis area.
News
2025.04 🌟 We introduce mindcoder.ai, a web application designed to support automated qualitative analysis. The user only needs to follow three steps to obtain qualitative analysis results-1) upload data, 2) start coding, and 3) get analysis report! See how to use-video.
2025.03 🚀 Started my postdoc fellowship at Johns Hopkins University!
2024.12 🚀 I will join the Malone postdoctoral fellow program at Johns Hopkins University next March! I will be working with Mark Dredze, Ziang Xiao and Chien-Ming Huang to explore the potential of LLM in qualitative analysis methodology usage in healthcare.
New Works
I explored a few new topics last year, including 1) MindCoder, 2) the full extension of Human-LLM interaction modes, and 3) CodeMap, a tool designed for code understanding. In particular, one of our most excited works has provided a functional tool named MindCoder, which supports automated qualitative coding within 3–5 minutes. You can access it via mindcoder.ai.
