In 2015, he completed his Ph.D. in computer science at the University of Memphis, where he studied under Dr. Santosh Kumar, director of MD2K. His primary areas of research are machine learning and wearable sensors. While at the University of Memphis, he also participated in the WiSeMANet lab (Wireless Sensors and Mobile Ad Hoc Networks), working on the development of machine learning models to make robust and reliable inferences of health risk behaviors such as smoking, drug intake and stress from physiological signals collected by wearable sensors.Md.
