Open to tenure-track Asst. Professor — Civil Engineering / Transportation

Engineering smarter, safer transportation systems.

I'm Sagar Dasgupta — a Research Engineer in the Department of Civil, Construction & Environmental Engineering at the University of Alabama. My research advances the safety, efficiency, and resilience of intelligent transportation systems — from real-time digital twins of urban traffic, to connected & automated vehicles, to AI-driven decision-making for the next generation of mobility.

About

A transportation systems engineer working at the intersection of traffic, vehicles, and AI.

I'm a Research Engineer in the Department of Civil, Construction & Environmental Engineering at the University of Alabama, with a research home at the USDOT National Center for Transportation Cybersecurity & Resiliency (TraCR). My research advances the safety, efficiency, and resilience of intelligent transportation systems through three intertwined threads: (1) real-time digital twins for adaptive traffic-signal control and vulnerable-road-user safety, (2) connected and automated vehicle (CV2X / AV) systems — including sensor fusion, AV navigation, and post-quantum-secure V2X communication, and (3) AI and data science for traffic flow analysis, work-zone safety, audio-based safety analytics, and rural-road risk assessment.

I completed my Ph.D. in Civil Engineering (Transportation) at UA in 2024 under Professor Mizanur Rahman. My dissertation, Cyber-Resilient Positioning and Navigation for Autonomous Ground Vehicles, sat at the intersection of transportation operations and CPS safety. My committee included Steven Jones (Civil), Alexander Hainen (Civil), Thejesh Bandi (Physics), and Jordan Larson (Aerospace). Before UA I earned an M.S. in Mechanical Engineering from Clemson (2017–2020) and a B.Tech. from MNNIT Allahabad (2011–2015). Between MNNIT and Clemson I spent two years as a Senior Engineer at HMCL Niloy Bangladesh doing production planning at one of South Asia's largest two-wheeler plants — that industrial grounding still shapes how I think about deployable transportation systems.

My research is supported by the National Science Foundation (CRII and CAREER awards), the USDOT National Center for TraCR, the Federal Motor Carrier Safety Administration (FMCSA), and the Alabama Transportation Institute. I am a Co-PI on seven funded transportation research projects (2025–2026) spanning resilient positioning & timing infrastructure, post-quantum V2X, EV-charging security, work-zone safety, and policy guidance for transportation cyber-physical-social systems. I serve on multiple Transportation Research Board (TRB) committees, am a member of the Institute of Navigation and the IEEE VTS Committee on Autonomous Vehicles, and Guest Editor for a 2026 Vehicles (MDPI) special issue on Data-Driven Intelligent Transportation Systems. I led the ITE Student Chapter at UA as President from 2022–2024.

I'm currently seeking a tenure-track Assistant Professor position in a Civil Engineering or Transportation Systems Engineering program, and am open to collaboration on proposals. If your group works on intelligent transportation systems, traffic operations, transportation safety, AV deployment, digital twins, or transportation cyber-physical systems — I'd love to talk.

Beyond the lab

I helped design three Alabama K–12 STEM modules with the Alabama Transportation Institute and Dr. Joni Lakin, distilling transportation research for middle- and high-school classrooms. Outside work I play the cajon, am a serious devotee of Bengali food, take photographs wherever I travel, and feel most alive in the mountains or by the sea.

Research

Three threads of transportation systems engineering — where infrastructure, vehicles, and AI meet.

From real-time digital twins of urban intersections, to safety apps for vulnerable road users, to AI-driven work-zone & rural-road safety, to cyber-resilient AV navigation — here's a map of what I work on, why, and where it's heading.

Research Vision

My long-term goal is to build a research program at the intersection of transportation operations and cyber-physical systems — one that closes the gap between theoretical models and deployed infrastructure. The lab I would lead at a Civil Engineering / Transportation department would advance real-time digital twins for adaptive urban networks, develop resilient sensing and control for connected and automated vehicles, and apply AI to road-safety problems that current methods fail on — work-zone safety, rural-road risk, vulnerable road users. The thread that ties these together is a commitment to systems that ship: methods proven on real hardware and real corridors, not just simulators.

Teaching & Mentoring

Training the next generation of transportation systems engineers.

My teaching philosophy: pair every formal idea with a physical system the students can build, break, and measure. I've taught traffic flow theory, transportation engineering, surveying, and transportation cyber-physical systems at UA, and helped develop K–12 STEM modules with the Alabama Transportation Institute.
