He is a pioneer in the area of location privacy, developing techniques for enhancing the privacy of location data and demonstrating how they can be incorporated into real-time traffic or other vehicle telematics systems. Through related research he conceived and directed a project to conduct a security and privacy evaluation of wireless systems in cars, using the tire pressure monitoring system as a case study. He also co-invented an app that relies on fine-grained localization of a mobile phone inside a car to distinguish a driver’s phone from a passenger’s phone to reduce distractions (e.g., silence incoming text messages). This project received a best paper award from ACM MobiCom and an Innovator’s Award from the New Jersey Inventors Hall of Fame.
