18 Feb Lalit K. Rajendran

Lalit Rajendran was a PhD candidate in the School of Aeronautics and Astronautics at Purdue University, researching image-based fluid density diagnostics using Background Oriented Schlieren (BOS). He has developed new tools and methodologies that have yielded improvements in the accuracy, precision and spatial resolution of the method compared to the state of the art. In addition, he developed the first uncertainty quantification methodology for density estimation from BOS.  He received his Master’s degree in Aeronautics and Astronautics also from Purdue with work focused on oil-film-based skin friction measurements on swept wings and holds a Bachelor’s degree in Aerospace Engineering from the Indian Institute of Technology (IIT), Kharagpur.
