About Me

Education:

  • PDF in Mechanical & Aerospace Engineering (Princeton University (2016 - 2018))
  • PhD in Mechanical Engineering (University of Calgary (2011 - 2016))
  • B.Sc. in Mechanical Engineering (University of Calgary (2006 - 2011))

Research

My research focuses on both fundamental and applied topics in fluid mechanics and computational fluid dynamics (CFD). Specifically, I work on the following research areas:

  • Vortex Dynamics in Unsteady Wakes: i.e., Sharp-edge bluff bodies, Oscillating Panels & Airfoils
  • Bio-inspired Design of Propulsors & Energy Harvesting Technologies
  • Turbulence modelling of unsteady and quasi-steady wakes: i.e., Non-Linear Eddy Viscosity Model
  •  Alternative Energy Systems: i.e., Wind, Solar and Geothermal Energy Extraction Technologies
  • Aerospace Technologies: i.e., Analytical Model of High-Temperature Vertical Boundary Layers, Magneto-Plasma-Dynamic Thrusters (MPDT)
  • Cardiovascular Flows
