CV | Research Statement | Teaching Statement

I co-direct the Laboratory for Mobile Sensing and Ubiquitous Computing (MOSAIC Lab) at UMass. My research focuses on design and development of the next generation mobile health sensing technologies that (1) capture observable low-level physical signals from our bodies and surrounding environments in the form of acoustic and electromagnetic waves, (2) map them to relevant biological and behavioral measurements, (3) run all the necessary computation in low power and resource settings. My research interest lies in the intersection of Mobile and Ubiquitous Computing, Signal Processing, Applied Machine Learning, Health and Behavior Modeling.

I received my Ph.D. in Information Science from Cornell University in 2017, M.S. in Electrical Engineering from the University of Texas at Dallas in 2012, and B.S. in Electrical and Electronic Engineering from Bangladesh University of Engineering and Technology in 2009.
