Greetings! Welcome to my website

In the current role (5/15/2023 - till date) as a Traffic Engineer in AECOM Phoenix office, I am working with Traffic department in all aspects of traffic engineering related services such as traffic projections, traffic impact studies, traffic analysis and simulation, traffic safety analysis/studies, and other transportation related studies. 

Previously, I worked as a Post-Doctoral Research Associate in the Wyoming Technology Transfer Center at the University of Wyoming, Laramie, Wyoming. I joined the University of Wyoming transportation group in fall 2016 as an MS student. I earned a Ph.D. in Civil Engineering, majored in Transportation Engineering, and minored in Statistics from University of Wyoming (UW) in 2020. Earlier, I completed B.Sc. in Civil Engineering from Khulna University of Engineering and Technology (KUET), Khulna, Bangladesh in 2013. 

Over the past 6 years, I have been working on various aspects of transportation-related issues such as freight operation and safety, occupant (i.e., driver and passenger) protection, tire failures, infrastructure cost-benefit analysis, passing sight distances for overtaking truck platoons, new alternative design to improve the performance of failing service interchanges, and implementation of updated grade severity rating system (GSRS) for Wyoming mountain passes. All of my research works hold a unique place in the field because they aimed to fill significant knowledge gaps that were not previously explored. Working on various aspects of transportation-related issues helped me to be an expert researcher in the area of traffic safety, traffic operation, and traffic simulation. During these years, I have acquired many skills such as application of advance statistical technique to develop safety assessment models, creation of microsimulation models to analyze operation and safety of transportation infrastructures, and writing several high-level scientific manuscripts and publishing those in different prestigious peer-reviewed journals. 

I have been providing technical and research assistance to several clients including the United States Department of Transportation (US DOT) - Federal Highway Administration (FHWA), Mountain-Plains Consortium (MPC), and Wyoming Department of Transportation (WYDOT). In addition, I have been serving as an active reviewer of the Transportation Research Board (TRB) and Transportation Research Record (Journal of TRB). 

My works are expected to assist highway agencies and policymakers take necessary actions in reducing traffic crashes and improving the overall operational performance by targeting appropriate strategies and proper resource allocation.
