FOR IMMEDIATE RELEASE
December 9, 2024 – Reston, Va. – The American Institute of Aeronautics and Astronautics (AIAA) proudly congratulates its newly elected Class of 2025 Honorary Fellows and Fellows. The class will be inducted during a ceremony on Tuesday, 29 April, in Washington, DC, and celebrated during the AIAA Awards Gala on Wednesday, 30 April, AIAA Awards Gala tickets will be available in early 2025.
“Congratulations to each member of the Class of 2025 AIAA Honorary Fellows and Fellows for their remarkable accomplishments. They are among the most respected names in the aerospace profession,” said Dan Hastings, AIAA President. “These distinguished individuals have earned the respect and admiration of the global science and engineering community. We are in awe of their creativity and exceptional contributions that have advanced aerospace.”
Honorary Fellow is AIAA’s highest distinction, recognizing preeminent individuals who have made significant contributions to the aerospace industry and who embody the highest possible standards in aeronautics and astronautics. In 1933, Orville Wright became the first AIAA Honorary Fellow. Today, 245 people have been named AIAA Honorary Fellow.
AIAA confers Fellow upon individuals in recognition of their notable and valuable contributions to the arts, sciences or technology of aeronautics and astronautics. Nominees are AIAA Associate Fellows. Since the inception of this honor 2,092 persons have been elected as an AIAA Fellow.
“The Class of 2025 Honorary Fellows and Fellows are impressive aerospace professionals. They are dreamers who have transformed our understanding of flight and exploration, pushing the boundaries of human potential. I am privileged to call them friends and colleagues. Their groundbreaking work reminds me that innovation is born from passion, persistence, and the audacious belief that we can always reach a little further than we thought possible,” added AIAA CEO Clay Mowry.

Stephen Monroe just completed his first year as an M.S. student in Mechanical Engineering at Clarkson University. He received his B.S. from Clarkson University in 2022. In his senior year, Monroe began learning CFD algorithms and HPC in the research group of Professor Chunlei Liang. During the first year of graduate study, Monroe conducted URANS studies of an ONR waterjet propulsion unit on parallel computers. He also is performing large eddy simulations of the same propulsion system to examine finer flow structures. Monroe is determined to become a skillful computational fluid dynamicist in large eddy simulations using an open-source code before completing his M.S. program. While uncertain about his future in academia, Monroe intends on using the skills he has developed to become a proficient propulsion system designer.“Coming into the Graduate School, I only intended on achieving an M.S. degree. Having been recognized for my hard work by the Abe Zarem award, not only has my passion for research been rejuvenated, but my consideration of furthering my education has as well,” said Monroe.
Monroe’s faculty advisor, Chunlei Liang, is Professor of Mechanical and Aerospace Engineering at Clarkson University. He received his Ph.D. from the University of London in 2005. Liang is an ASME Fellow and an AIAA Associate Fellow.
Quentin Roberts is an M.S. student at the University of Washington studying aeronautics and astronautics with a concentration in fluids. His research is on injector mixing in rotating detonation rocket engines (RDREs). Roberts will start work in fall 2023 as a propulsion analyst at Blue Origin. “Receiving this award will allow me to greatly expand my horizons in the world of astronautics by not only providing an opportunity to learn about what research the international community is working on, but also an opportunity to present my own research to an international audience,” said Roberts.
Roberts’ faculty advisor, Carl Knowlen, received his bachelor’s and master’s degrees in Aeronautical and Astronautical Engineering from the University of Washington in 1983 and 1985, respectively. He continued with his graduate research on ram accelerators at the UW and completed his Ph.D. program in 1991. Dr. Knowlen then accepted a Postdoctoral Research Associate position with the UW Department of Aeronautics and Astronautics and has been teaching AA Department courses on a regular basis since 2002.
