Personal profile

Research Interests

Patankar group research is focused on four primary missions: First, to develop fully resolved computational fluid dynamics (CFD) techniques to simulate muscle activated movement of organisms (e.g. knifefish, zebrafish) and organs (e.g. esophagus). Second, to use theory and CFD to understand the neural control of movement, to design novel underwater vehicles, and to interrogate the evolution of fish form and function. Third, to establish the foundational science of controlling phase (anti-icing, anti-frosting, boiling, condensation, non-wetting supehydrophobic surfaces) using surface roughness and chemistry. Fourth, to establish new metrics to quantify the mileage efficiency and greenhouse emissions of automotive vehicles.
