Research Interests

  • Multi-disciplinary analysis and design optimization
  • Applied & computational aerodynamics
  • Design of unconventional vehicles


  • Working on parametric design of natural laminar airfoil (NLF) with improved aerodynamic performance at various flight conditions including off design characteristics for green futuristic commercial vehicles.
  • Working on design space exploration to identify novel shapes and approaches to dramatically reduce the aerodynamic drag of airborne pod under the various operational conditions.
  • Grand Challenge: Working towards NASA's Environmentally Responsible Aviation (ERA) Competition as a part of team of 8 graduate students. As a lead of aerodynamic group, working on advanced vehicle concept, physics based design and advance technology to reduce drag and increase overall aerodynamic performance to achieve NASA's N+2 timeframe goals of reduced emission, fuel burn and noise.
