MEI Research applies an understanding of health and behavior science to provide technology solutions for basic and clinical investigations. We are engineers who create software, sensors and algorithms for free-living environments, including ecological momentary assessments and intervention (EMA/EMI), energy expenditure and behavior change, all within related social / environment context. MEI designs, builds and renovates whole-body respiration calorimeters to measure minute by minute energy expended and substrate utilization. MEI supports entire research projects with study automation, data management and technical support services.
