I enjoy shipping tools, deploying practical AI, and building dependable data and ML systems—in production, side projects, and transportation research.
About
I am an AI Engineer with the U.S. Department of the Treasury. I hold a Ph.D. in transportation engineering from the University of California, Berkeley, with deep experience in traffic engineering, transportation operations, and the impact of automated vehicles on mobility. My expertise extends to data analytics, machine learning, and computational modeling, which I apply to build reliable analytical systems and to optimize transportation networks.
My doctoral research focused on Adaptive Cruise Control (ACC) vehicles and their effects on urban congestion, leveraging data-driven simulations and predictive modeling. I also earned an MS in Civil and Environmental Engineering from UC Berkeley and a Diploma of Engineering (BS & MEng) from the National Technical University of Athens, where I specialized in Transportation Engineering with a minor in Surveying Engineering.
My work integrates advanced data science techniques, machine learning algorithms, and traffic simulation models to enhance transportation planning, operations, and decision-making. I am particularly interested in how emerging mobility technologies and AI-driven solutions can transform the future of urban transportation.
