Hello world! Welcome to my website. I am an R&D Staff at the Oak Ridge National Laboratory (ORNL). My job at the ORNL focuses on studying how people (passengers) and goods (freights) move in the United States. My recent research also revolves around the application of sensing and emerging technologies in transportation, including infrastructure management, work zone safety, and intelligent vehicles. I enjoy working with students and learning with them. I am passionate about developing tools that people really use. Outside of academia, I have been a choir member for over 20 years and an occasional tenor soloist; I like to take pictures, and I enjoy sports. I hope you can find useful information on this website and please feel free to contact me.
