Much of Dr Godino’s research funded by the National Institutes of Health focuses on the development and evaluation of interventions that utilize mobile and wearable technology (e.g., smartphones, accelerometers, and heart rate monitors) to promote healthy changes in physical activity, sedentary behavior, diet, and sleep for the prevention of obesity, diabetes, and cardiovascular disease. He is also actively engaged in the development and evaluation of on- and off-body sensors that measure various components of human physiology and behavior, as well as systems that trigger active data collection in response to data that is passively acquired.
