Dr. Kader Frendi obtained his graduate degrees in applied mathematics and mechanical engineering from Brown University. After graduate school, Dr. Frendi spent one year at Northeastern University in Boston as a Visiting Assistant Professor in the Mechanical Engineering Department. In the fall of 1990, he joined NASA Langley Research Center as a research contractor in the Structural Acoustics Branch. During his years at NASA Langley, Dr. Frendi supported several key programs starting from the basic research program to the High Speed Civil Transport (HSCT) program and the Hyper-X program (also known also as X-43A). Dr. Frendi made key contributions to these programs and his work was published in well-known journals. In the fall of 1999, Dr. Frendi joined the Mechanical and Aerospace Engineering Department at The University of Alabama in Huntsville as an Associate Professor. Dr. Frendi built a vibrant research program in Computational Fluid Dynamics and more specifically in Unsteady Flows and Acoustics. Dr. Frendi attracted funding for his research from various NASA centers and the DoD to support his graduate students. Dr. Frendi built a transmission loss facility capable of testing acoustic transmission through aircraft type panel and measuring acoustic signatures from MAVS. Dr. Frendi is a recipient of the UAH Foundation Award for Research and Creative Achievement, 2004, and the College of Engineering Distinguished Senior Faculty Award, 2016. Dr. Frendi served as Chairman of the MAE Department for three years, December 2007 to December 2010. Dr. Frendi is a Fellow of ASME, an Associate Fellow of AIAA and an Associate Editor of the AIAA Journal of Propulsion and Power.
