PhD Student at Georgia Tech studying Human-Centered Computing with a specialization in Human-Computer Interaction (HCI).

In my research, I explore the design and evaluation of explanations in Conversational AI systems and their role in aging in place for older adults with Mild Cognitive Impairment (MCI). I'm interested in studying how different approaches to explainability and transparency in collaborative AI systems can improve the conversational user experience. My research interests broadly include Human-AI Interaction, Explainable AI and designing for older adults. My advisors are Dr. Elizabeth Mynatt and Dr. Sonia Chernova in the School of Interactive Computing at Georgia Tech and my research is primarily supported by Emory's Brain Health Center and the NSF AI Institute for Collaborative Assistance and Responsive Interaction for Networked Groups (AI-CARING).
