Hi! I am a third year PhD Student at Georgia Tech studying Human-Centered Computing (HCC) with a specialization in Human-Computer Interaction (HCI).

In my research, I explore the human-centered design and evaluation of natural language explanations in Conversational AI systems and their role in aging in place for older adults and their caregivers. I'm interested in studying how different human-centered approaches to explainability and transparency in sociotechnical and collaborative AI systems can improve the conversational user experience. 

My research interests include Human-AI Interaction, Human-Centered Explainable AI and designing for older adults. My doctoral advisors are Dr. Elizabeth Mynatt and Dr. Sonia Chernova in the School of Interactive Computing at Georgia Tech and my research has been generously supported by Emory Healthcare's Brain Health Center and the NSF AI Institute for Collaborative Assistance and Responsive Interaction for Networked Groups (AI-CARING).
