About

Dr. Umberto Saetti is an Assistant Professor in the Department of Aerospace Engineering at Auburn University. Prior to Auburn, he held appointments as Postdoctoral Fellow in the Daniel Guggenheim School of Aerospace Engineering at Georgia Tech and as Visiting Scholar at the U.S. Army Aviation Development Directorate at NASA Ames. Dr. Saetti holds a Ph.D. in Aerospace Engineering (with a minor in Computational Science), an M.Sc. in Aerospace Engineering, and an M.Sc. in Electrical Engineering from Pennsylvania State University. He received his B.Sc. in Aerospace Engineering from Politecnico di Milano, Italy.

Dr. Saetti's research focuses on modeling, simulation, order reduction, and control of high-order models of the coupled flight dynamics, aerodynamics, and aeroacoustics of aircraft, rotorcraft, and biologically-inspired flying vehicles. These models are used for studies involving immersive simulations that make use of Extended Reality (XR), human-machine interaction, synthesis of advanced flight control laws, development of innovative pilot cueing methods, and fundamental understanding of the stability of flapping-wing flight.

Dr. Saetti is the recipient of the Barnes McCormick Memorial Scholarship, awarded by the Vertical Flight Foundation (VFF) for outstanding accomplishments as a doctoral candidate in the vertical flight field.

News

I have multiple MS/PhD position openings in my newly-formed lab, the Extended Reality Flight Simulation and Control Lab, withing the Department of Aerospace Engineering at Auburn University. Research topics include human-machine interaction, innovative pilot cueing methods, and development of advanced flight control laws for vehicles including fixed-wing aircraft, rotorcraft, and flapping-wing MAVs. Funding opportunities are available for students with an interest in aerospace vehicles modeling and simulation, flight dynamics and control, system identification, and scientific programming. Those who are interested should contact me at their earliest convenience at saetti@auburn.edu including their CV, research interest, and experience (if any).
