Much of my thesis work focuses on empowering the next-generation transportation ecosystem that is comprised of vehicles, environment, and humans. This research includes a suite of novel and scalable sensing technologies for facilitating safer and more efficient transportation that has a profound impact on people.

The synergy of my thesis works is illustrated in the above figure. My research investigated ubiquitous sensing, vehicular system, and wireless communication. These three elements are cornerstones for tackling real-world challenges on our roads.

LibreCAN: Automated CAN Message Translator
CCS 2019

LibreCAN can be used for automated translation of in-vehicle data, thus making the data flow in cars "transparent" to developers. In the future, we may be able to build apps on cars as easy as developing apps on smartphones!

TurnsMap: Enhancing Traffic Safety with Crowdsensing and Deep Learning
UbiComp 2019

This work presents TurnsMap, an IoT + AI framework for automatically detecting if a left turn is safe, e.g., whether it has protection for left-turning cars. Democratizing this information can help assure traffic safety for various transportation applications, e.g., navigation and ride-sharing apps.

Mobile IMUs Reveal Driver's Identity from Vehicle Turns
ArXiv Preprint, 2017

This work presents Dri-Fi, a solution that enables automotive apps to identify the person behind-the-wheel by only using mobile sensors. The capability of identifying driver is essential for personalized service/assistance for the driver and his/her designated parties, thus can benefit various automotive apps


Locating and Tracking BLE Beacons with Smartphones
CoNEXT, 2017

LocBLE is able to locate specific location of any surrounding Bluetooth low energy (BLE) beacons by justing using your smartphone. Comparing to existing coarse-grained BLE ranging applications, LocBLE is capable of enabling various use cases in Internet-of-Things. This is a collaborative work with Hewlett Packard Labs during my internship.

Vulnerability and Protection of Channel State Information in Multiuser MIMO Networks
CCS, 2014

This work investigated vulnerability in MU-MIMO. Focus on plaintext feedback of estimated channel state information (CSI) from clients to the APs. We have found a malicious user could use sniff attack power attack by utilizing the vulnerability in existing CSI feed scheme.
