Haowen Xu

Research Scientist



Dr. Haowen Xu is a research scientist in the Computational Sciences and Engineering Division at Oak Ridge National Laboratory. Dr. Haowen Xu received his Ph.D. in Civil and Environmental Engineering and a graduate certificate in Geoinformatics at the University of Iowa in 2019. Before that, he got his M.S. degree in Civil and Environmental Engineering from the University of Iowa in 2015. His research interests focus on developing cyberinfrastructure, digital twins, visual analytical dashboards, mobile edge computing apps, Virtual Reality (VR) serious games, and cyber-physical systems to facilitate the planning and management, experimental research, and data and model-driven analytics in the environmental and urban science sectors. He has successfully designed and developed many research software and mobile/web applications for a number of projects funded by the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy (EERE), Vehicle Technologies Office (VTO), and Building Technologies Office (BTO), and other federal agencies, such as the U.S. Army Corps of Engineers (USACE) and Federal Highway Administration (FHWA). His domain interests include smart cities, intelligent transportation systems, smart buildings, human modeling, and water resources management (e.g., erosion and sediment transport, watershed planning, and hazard mitigation). 

Dr. Xu has authored and co-authored over 15 journal publications, including several premier journals such as IEEE Transactions on Intelligent Transportation, Science of the Total Environment, Environmental Modelling & Software, Journal of Environmental Management, and Journal of Hydrology. He has also received research awards from the Institute of Electrical and Electronics Engineers' International Conference on Mobile Ad-Hoc and Smart Systems (IEEE-MASS), the International Building Performance Simulation Association (IBPSA), and the American Water Resources Association (AWRA). He is a co-organizer of the ACM-SIGSPATIAL’s International Workshop on Computational Transportation Science (IWCTS 2022), and he has been invited to present his research at the National Academy of Sciences (NAS), the United States Environmental Protection Agency (USEPA), and U.S. Army Engineer Institute for Water Resources (IWR).
