Seetha Raghavan

Dr. Seetha Raghavan is Associate Dean of Research and Graduate Studies of the College of Engineering at Embry-Riddle Aeronautical University Daytona Beach campus. She received her doctoral degree in Aeronautics and Astronautics from Purdue University in 2008 and her masters degree in Aeronautics and Space Technologies at SUPAERO, France. Prior to this, she completed her Bachelors in Mechanical Engineering at Nanyang Technological University, Singapore. She is an Associate Fellow of the American Institute of Aeronautics and Astronautics and the Editor-in-Chief of AIAA's Progress in Astronautics and Aeronautics Series. 

Dr. Raghavan came to Embry-Riddle after serving as a faculty member for 14 years at the University of Central Florida (UCF) most recently as Director of the Aerospace Engineering Graduate Program in their Mechanical and Aerospace Engineering Department. She was instrumental in leading the development of the PhD program in Aerospace Engineering to its successful launch in 2019 following final approval by the State, in the process spearheading the addition of multiple new graduate courses and a new 5-year course offering plan. Her leadership of the program led to a growth in enrollment to 60 doctoral students with 20 AE doctoral degrees awarded by the end of her tenure in 2023. 

Dr Raghavan’s research has a focus on investigating the mechanics of high temperature coatings for extreme environments in propulsion, hypersonic flight, space exploration and energy applications as well as developing multifunctional sensing materials for wear and impact resistance, structural integrity and damage detection. Over the last 20 years, her research has contributed to knowledge for future aerospace materials and structures, while initiating international collaboration and bringing fundamental research to industry. Her work has been funded by the National Science Foundation, NASA, Department of Energy’s National Energy Technology Laboratory (NETL), DARPA and industry as lead investigator. The outcomes of her work have been published in journals such as Nature Communications and Acta Materialia. Her international focus in research has connected more than 20 US scientists from various Aerospace fields with partners abroad and provided over 30 US students international research experiences. She has developed key innovative technologies in areas of functional high temperature coatings for optical diagnostics for major aerospace engine industry partner adoption and has patents filed and awarded. 

Dr Raghavan has taught 6 different courses during her time at UCF at the graduate and undergraduate level and developed 3 new graduate courses Aeroelasticity, Non-Destructive inspection in Aerospace Structures and Engineering Design of Aerospace Vehicles. Her consistent efforts have been recognized with the UCF College of Engineering Teaching Incentive Program award for sustained high levels of teaching effectiveness twice, in 2013 and in 2019. She has been honored with a university wide Reach for the Stars award for collective accomplishments in Research, Teaching, Mentoring and Service. Students in her laboratory have won over 20 prestigious fellowships including NSF and NDSEG Fellowships, Fulbright awards, Zonta International Amelia Earhart Fellowship, Christine Mirzayan Science and Technology policy Fellowship and more. She was honored nationally with the Women in Aerospace Educator Award in 2019. She is active in service to the Aerospace, Mechanics and Materials community as a member of AIAA since 1996 and Women in Aerospace.

Dr Raghavan has 7 years of work experience in the aerospace industry at Singapore Technologies Aerospace (a subsidiary of ST Engineering) where she was a senior engineer involved in Aircraft Structural Analysis, Aircraft Maintenance, Repair & Modifications. Her notable contributions include internal loads, stress analysis and weight and balance computations for the structural upgrade of F-5 aircraft and research & development in Automated non-destructive inspection for Fatigue cracks detection using Ultrasonic and Eddy current techniques for which she holds a joint patent. During her time in France, she worked with Messier Bugatti in Vélizy, designing and executing the static and fatigue test plan for the S-92 wheels and brakes.
