HABits Lab

Where Preventive Medicine
Meets Computer Science

Designing, building and analyzing end-to-end mhealth
systems to help answer health-related questions.

Nabil Alshurafa

Ph.D., Director of HABits Lab
Northwestern University

Our lab is at the intersection of computer science and preventive medicine. Through analysis of continuous streams of data provided by smartphones and wearable sensors, we use signal processing intelligence and machine learning to understand a person’s moment-to-moment behavior, psychological states, and environmental context in which the behavior occurs. We design, build, and analyze end-to-end mobile health (mHealth) systems, while focusing on processing its data to help answer health-related questions.

It is the humanity within us and the desire to improve quality of life and healthcare costs that guide our solutions to the persisting health problems of our time through computer science and behavior science based research in passive sensing data analytics. Our goal is to advance our ability to understand, detect, predict, and ultimately prevent problematic health habits. We are the Health Aware Bits (HABits) Lab!

Frequently Asked
Questions

We design, build and analyze end-to-end mHealth systems, while focusing on processing its data to help answer health-related questions. We focus on signal processing and machine learning techniques to process time-series data generated from passive sensors. To advance existing sensing techniques, a part of our lab focuses on the design of embedded systems.

People in HABits Lab have diverse backgrounds including Computer Science, Statistics, Electrical Engineering, etc. We conduct interdisciplinary researches in HCI, design, AI, machine learning, behavior science and computational medicine.
