Dr. Taber Wanstall joined the University of Dayton in 2021 after receiving his Ph.D. from the University of Alabama the year prior. His research interests cover a wide array of topics in the thermal-fluid sciences including: fuel sprays and combustion, real-fluid thermodynamics and supercritical mixing, development and implementation of quantitative optical diagnostics, two-phase flow, and hydrodynamic stability. In his research, he seeks to corroborate first principle/mathematical understandings with experimental validations. Currently (2021), Dr. Wanstall has authored 11 journal publications.
