I'm a PhD student in Human-Centered Computing (HCC) at Georgia Tech specializing in Human-Computer Interaction (HCI).

My research focuses on using human-centered design methods to build assistive and explainable AI systems in social environments, with current focus on aging in place. I'm particularly interested in the design of explanations in such AI systems, focusing on how people ask for and perceive explanatory instances in assistive AI technologies. My work centers the application of human-centered approaches to study explainability in AI systems, and highlights the need for human-AI interactions to be informed by information sources external to the AI, accounting for a sociotechnical awareness of context. My research is part of an ongoing collaboration between Emory Healthcare (Atlanta), Carnegie Mellon University (Pittsburgh) and Northeastern University (Boston). 

My doctoral advisors are Dr. Elizabeth Mynatt and Dr. Sonia Chernova in the School of Interactive Computing at Georgia Tech, and I also work with Dr. Agata Rozga at Georgia Tech. Over the years, my research has been generously supported by Emory Healthcare's Brain Health Center, NSF AI Institute for Collaborative Assistance and Responsive Interaction for Networked Groups (AI-CARING) and the George Family Foundation Fellowship for Innovation in Health Systems. My work has been published at ACM CHI, CSCW, ASSETS, GROUP and UCAml, and has won a best paper award at ACM ASSETS.  

Not very long ago, I was a Masters Student in HCI at Georgia Tech where I developed my research and design thinking and worked on many interesting projects -- from designing a safety solution for bikers on the road to understanding the use of conversational agents by older adults with early-stage dementia and their caregivers.
