Research Description
My research program involves evaluating the usability and effectiveness of technology-delivered health interventions, with a focus on user engagement, type 2 diabetes, and vulnerable populations. I aim to examine more critically how patients engage with technology-based interventions in order to design interventions that optimize engagement, and in turn, outcomes among underserved adults.
