Research
I am currently working in the area of the design of personal sensing applications for healthcare and rehabilitative medicine purposes.
Specifically, I have been designing, building, and evaluating a mobile wayfinding system that assists individuals with cognitive
impairments, for
Project ACCESS.
More broadly, my interests lie in the intersection of ubiquitous and mobile
computing technologies, human-computer interaction, and activity recognition.
I am particularly interested in studying impactful applications that address both end-user and system designer needs and concerns.
