Dr. Ebenezer P. Gnanamanickam obtained his MS and PhD in Aeronautics and Astronautics from Purdue University in December 2003 and May 2010, respectively. 

Following his doctorate, he was a Visiting Assistant Professor at Purdue University from 2010-2012. From September 2012-July 2013, he was a post doctoral fellow at the University of Melbourne, Mechanical Engineering, Australia.

In the Spring of 2016 Ebenezer won a grant under the Air Force Office of Scientific Research's (AFOSR) Young Investigator Research Program. His other current and recent funding sources include Army Research Office (ARO)/Office of Naval Research (ONR) through the Penn State & Georgia Tech. Vertical Lift Research Center of Excellence (VLRCOE), an ONR DURIP, an accelerated research initiative (ARI) grant aparts from grants from the National Science Foundation (NSF) and ARO.

His research focuses on understanding wall turbulence, controlling it, applied aerodynamics and measurement techniques
