01 / Research
Making road quality measurable.
My work connects pavement materials, construction processes, and sensing technologies. A central question is how to detect segregation and other quality variations early enough to improve decisions on site.
Image-based evaluation
Quantifying aggregate structure and pavement uniformity with image processing and deep learning.
Pavement performance
Studying materials, durability, and infrastructure condition to support better maintenance decisions.
