Nazib Siddique is currently serving as a Transportation Energy Analyst within the Energy Systems and Infrastructure Analysis Division at Argonne National Laboratory. His research primarily focuses on several key areas, including the dynamic interplay between electric vehicle (EV) adoption and the deployment of charging infrastructure. He also investigates the energy, environmental, and economic implications associated with alternative fuels, vehicle technologies, freight modes, energy systems/technologies, and mobility trends at both regional and national scales. 

Furthermore, Nazib demonstrates a keen interest in the domain of alternative fuel energy technology, particularly in the context of decarbonizing rail transportation. His work encompasses conducting life cycle analyses (LCA) and techno-economic analyses (TEA) to assess the viability and impact of alternate energy sources such as battery electricity, hydrogen, and biofuels. 

Nazib earned his Master of Science and Ph.D. degrees in Transportation Engineering from the University of Washington Seattle, and a Bachelor of Science in Civil Engineering from Bangladesh University of Engineering and Technology.
