I study the mechanics of fluid flows and particulate systems, ranging from fundamental research on novel flow phenomena and related applications to the development of new computational approaches for investigation of fluid and particulate flows. Areas of particular interest include: (1) multiscale vortex flow phenomena, such as observed in turbulent rotorcraft and pump flows; (2) biofluid flows, such as observed in biofilms and cardiovascular systems; (3) renewable energy problems, such as snow/particle mitigation from solar panels and wind turbine wake interference; and (4) acoustic effects on fluid and particulate systems.

Research Highlights and News
I am leading a team of UVM faculty working with scientists at the Army’s Cold Regions Research and Engineering Laboratory (CRREL) on a project to develop state-of-the-art sensing and decision-making tools for cold regions operations.
Under NSF funding, we are investigating a novel phenomenon in which ultrasound impingement onto a biofilm is used to enhance penetration rate of nanoparticles, which are a primary carrier medium used for biofilm mitigation.
Under NASA funding, we have developed a new hybrid approach for simulation of biofilm growth, which integrates the best features of discrete element and continuum modeling.
