Lab Director Biography

VP Nguyen is an Assistant Professor of Computer Science and Engineering at University of Texas at Arlington. His research identifies the opportunities for cyber-physical system-based solutions to monitor and improve human health conditions and their living environments. He has been building wearable, mobile, and wireless sensing systems to monitor human breathing volume, brain activities, muscle activities, skin surface deformation, blood pressure for various healthcare applications. He has also developed systems to monitor objects in the environment such as drones, cars, trees, etc. He obtained his Ph.D. degree in Computer Science from the University of Colorado Boulder in 2018, where he was supervised by Prof. Tam Vu. He is the recipient of Best Paper Award at ACM MobiCom 2019, Best Paper Runner up Award at ACM SenSys 2018, ACM SIGMOBILE Research Highlight 2017, Best Paper Nominee at ACM SenSys 2017, Best Paper Awards at ACM MobiCom-S3 2016-2017.

Research Overview

We hold the vision that wearable, mobile, wireless, battery-free sensing and intervention systems promise revolutionizing global scale applications across healthcare, environmental, agriculture, infrastructure management, and so on.

We explore and develop new sensor, hardware designs, software techniques and algorithms so that the developed systems work reliably in spite of frequent power failures, constrained resources, and unpredictable conditions.

Research Approach: We build fully integrated, end-to-end systems to demonstrate their scientific advancement on real-world settings environment. We run physical experiments to validate our hypothesis. We run user studies and clinical trials in the wild to test our technologies, gathering quantitative and qualitative results that inform future work.
