Hi! 👋️ I'm a PhD candidate in Human-Centered Computing (HCC) at Georgia Tech, where I'm advised by Dr. Beth Mynatt and Dr. Sonia ChernovaMy research broadly spans Human-Centered AI, Health Informatics, Aging, and Conversational AI Design. I design and evaluate LLM-based Conversational AI systems in social environments and in personal health management (such as for aging in place), with a particular emphasis on improving people's understanding of AI systems in data-rich health contexts through explanations of AI behavior. While technical advances have enabled AI systems to act more autonomously, they also introduce new challenges for people in understanding and appropriately relying on AI-generated information. I adopt a human-centered approach to study how explanations function in real-world human-AI interactions. In particular, my research investigates the challenges associated with how AI systems explain their behavior in practice and how those explanations influence users’ understanding, reliance, and oversight of AI systems over time.

 

I was recognized as a Foley Scholar Award Winner in 2025 (highest departmental award for research excellence in computing at Georgia Tech) and a George Family Foundation fellow for Innovation in Health Systems in 2022. My research has been published in leading venues in HCI, Accessibility and Ubicomp (e.g., CHI, CSCW, ASSETS, GROUP, UCAml), and has won a 🏆 Best Paper Award at ACM ASSETS 2022 and a 🏆 Best Poster Award at ACM GROUP 2025. My research has been generously funded by Emory Healthcare's Brain Health Center and the NSF AI-CARING Institute. ​

Prior to the PhD, I completed my Master's in Human-Computer Interaction (MS HCI) at Georgia Tech (2019-2021), during which I worked in the Everyday Computing Lab with Dr. Beth Mynatt and the Animal-Computer Interaction Lab with Dr. Melody Jackson. ​
