About Halil

Dr. Ceylan has extensive experience in pavement field investigation and forensic testing, pavement performance evaluation and modeling, mechanistic-based pavement analysis and design concepts, nondestructive testing and health monitoring of transportation infrastructure systems, smart infrastructure/engineering materials, innovative airfield pavement engineering solutions, and engineering application of intelligent data mining and computational and artificial intelligence techniques.

Over the course of his career, he has been involved with over 115 research projects – worth more than $20.8 million project funds since 2002 – related to transportation infrastructure systems and pavement/geo/engineering materials, serving as the principal investigator or co-principal investigator. Research sponsors include the National Science Foundation, Federal Highway Administration, Federal Aviation Administration, National Cooperative Highway Research Program, Strategic Highway Program, Portland Cement Association, various state departments of transportation and highway research boards, among others.

Dr. Ceylan has authored and co-authored over 345 peer-reviewed publications, which includes 6 edited books, 4 invited book chapters, more than 130 journal articles (plus 3 fully peer-reviewed Geotechnical Special Publications), and over 140 fully-refereed conference proceedings and technical reports. He is also an avid technical presenter, having delivered over 350, including more than 100 invited presentations at universities and conferences with several keynote lectures. During the course of his tenure at ISU, he has advised and mentored over 70 graduate students, postdoctoral research associates, and research staff.

And besides having served on the editorial board for 9 international journals, he has been a member of over 30 national and international committees and organizations, serving as the chair of the ASCE Geo-Institute (GI) Pavements Committee, chair of the newly-formed ASCE Transportation and Development Institute (T&DI) Task Force Committee on Unmanned Aircraft Systems (UAS) Impacts, and having organized and chaired many technical conference sessions for these professional associations.
