Biography

I am an exercise physiologist focused on the implementation of wearable devices for clinical care. I develop and assess the impact of in-person and biosensor-based behavioral interventions upon habitual physical activity for youth and adults with type 1 diabetes. My most recent publication, and the subsequent NIH career development award stemming from it, focus on using biosensors of multiple health behaviors as supporting material for human-delivered counseling of physical activity for adults with type 1 diabetes. I have also extended this work beyond clinical trials to implementation in both the consumer market and healthcare systems. For the consumer market, I led two international stakeholder panels that contributed to formation of the Sports Tech Research Network, with mission statement of bringing together research-driven professionals from academia, industry & sports field practice, with the common goal to create, bring to market & implement the most trustworthy and effective sports technology solutions based on science. I am a member of its special interest group developing a central global framework to evaluate wearable devices. For healthcare systems, I am leading stakeholder interviews and test cases to evaluate and recommend next steps in the integration of consumer-grade wearable devices into Veterans Health Administration (VHA) clinical workflow.
