I'm an HCI Researcher exploring the potential of conversational AI technology to assist older adults in their daily tasks.
My research interests broadly include Human-AI Interaction, Explainable AI and Conversational Assistants for older adults with Mild Cognitive Impairment. I'm interested in studying how different approaches to explainability in AI systems engender trust in them in the context of older adults for which I primarily employ use-inspired qualitative user research methods.

I'm fortunate to be advised by Dr. Beth Mynatt (Everyday Computing Lab) and Dr. Andrea Parker (Wellness Technology Lab).  

I'm also a Spring 2021 graduate of the MS - Human-Computer Interaction program at Georgia Tech. My masters research was focused on understanding the use of Conversational Assistants to support older adults with MCI for specific tasks such as medication management. 

When I'm not working, I can be found attempting to learn more about astronomy and stargazing, doing yoga or volunteering at Atlanta animal shelters.
