Research

  • Dr. Tilton's expertise is in theoretical and computational fluid mechanics with an emphasis on hydrodynamic stability and flow through porous media. He received his Ph.D. in 2009 from McGill University, after which he was a postdoctoral research fellow at the University of Aix-Marseille (2009-2011) and the University of Maryland (2011-2014). His research focuses on developing accurate analytical and numerical models of membrane filtration, carbon dioxide sequestration, and flow control for drag reduction. These applications play central roles in the water-energy-climate nexus, as well as the food, pharmaceutical, and petroleum sectors. Dr. Tilton's numerical work focuses on spectral methods, fractional step methods, and multi-domain methods. His analytical work focuses on perturbation methods and volume-averaged models of flow through porous media.
