Dr. Timothy V. Bartholomew
Research General Engineer, National Energy Technology Laboratory
Timothy V. Bartholomew, Ph.D., is a co-founder and principal consultant at Horizon Modeling Solutions, a consulting firm that provides advanced modeling and techno-economic analysis to accelerate the development and deployment of water treatment technologies. He specializes in mathematical optimization for process design, R&D strategy, and investment decision-making.
Previously, Dr. Bartholomew was a Process Systems Engineer at the U.S. Department of Energy’s National Energy Technology Laboratory (NETL), where he led the development of the Water Treatment Technoeconomic Assessment Platform (WaterTAP)—an open-source modeling library for simulating and optimizing advanced water treatment systems. WaterTAP builds on the IDAES platform, enabling rigorous, optimization-based models to support decision-making across R&D stages, including conceptual, bench, and pilot scale.
Dr. Bartholomew holds a B.S. in Chemical Engineering from Washington University in St. Louis and a Ph.D. in Civil and Environmental Engineering from Carnegie Mellon University.
