Research Interests

I am a Principal Research Scientist at Georgia Tech with over 16 years experience conducting research at the intersection of psychology, health, and human-centered computing. I leverage my background in psychological research methods and extensive experience in translational research to collaborate on developing and deploying innovative healthcare solutions that are tested in real-world and naturalistic settings. The focus of my work has spanned from autism to mild cognitive impairment, and from mobile applications to robotics. My mission is to bridge the gap between foundational research and impactful, scalable technologies that improve the lives of individuals and their care partners and providers.
