Ahmad Alhasan in an adjunct assistant professor and associate research scientist of transportation engineering. He developed assessment techniques to evaluate pavement surface condition using laser scanning technology. He has devised algorithms to autonomously process 3-D point clouds to detect distresses and evaluate ride quality. More recently, Ahmad has utilized advanced friction models to evaluate pavement friction using micro/macro-texture measurements. Ahmad is developing a new framework to evaluate reliability and risk of pavement performance to improve decision making and asset management.
