Ravindran is currently a professor at the University of Alabama in Huntsville, which he joined in 1999. Before coming to UAH, he held an NRC research fellow position in the Flow Modeling and Control Branch at NASA Langley Research Center. Prior to that appointment, he held a visiting assistant professor position in the Center for Research in Scientific Computation at North Carolina State University. He thanks both of these great institutions for the opportunities and mentoring and professional development.

As principal investigator of various research grants, he has conducted research for agencies such as the National Science Foundation, DOD, NASA Langley Research Center and NASA Marshall Space Flight Center. His research is currently supported by NASA under the grant #NNM16AA06A. He has also received NASA Summer Faculty Research Fellowship seven times and spent the summers in the Fluid Dynamics and Thermal Analysis Branch at the NASA Marshall Space Flight Center (MSFC).

He has been a visiting scholar at many institutions, including the IMA at the University of Minnesota, ICERM at Brown University, INRIA at the University of Bordeaux, ICASE at NASA Langley, IPAM at the University of California at Los Angeles, SAMSI at RTP and MSRI at the University of California at Berkeley.

He has to his credit 70+ refereed publications in journals such as SIAM Journal of Control and Optimization, ESAIM:COCV, ESAIM:M2AN, Numerishe Mathematik, IMA journal of Numerical Analysis, SIAM Journal of Scientific Computing, Numerical Methods for Partial Differential Equation, Numerical Functional Analysis and Optimization, Journal of Computational Physics, Computer Methods in Applied Mechanics and Engineering, AIAA Journal of Propulsion and Power, Numerical Methods for Fluids and other professional journals and proceedings. He has also given invited lectures in France, Austria, Spain, India, Canada and the United States, and at professional societies such as SIAM, IEEE, AIAA, and ASME.

His scientific expertise has been recognized by over 2000 citations (Google Scholar) of his publications and, by invitations to consult by industry and government labs and to serve in the Editorial Boards of a number of international journals. He has advised many graduate students and taught many graduate and undergraduate level courses in areas most related to modeling and analysis such as finite element methods, optimization & control, partial differential equations, numerical analysis, probability & statistics and matrix computations.
