About

I am a Postdoctoral Fellow in the Daniel Guggenheim School of Aerospace Engineering at Georgia Tech. I hold 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. I received my B.Sc. in Aerospace Engineering from Politecnico di Milano, Italy.

My research interests are in the area of aircraft and rotorcraft flight dynamics and controls, handling qualities, and system identification. Applications span civil and military helicopters, small- and medium-scale Unmanned Aerial Vehicles (UAVs), flapping-wing Micro Aerial Vehicles (MAVs), and electric Vertical Take-Off and Landing (eVTOL) vehicles intended for Urban Air Mobility (UAM). I have worked on multiple research projects within the Vertical Lift Research Center of Excellence (VLRCOE) sponsored by government agencies including the Federal Aviation Administration (FAA), U.S. Army, and U.S. Navy. As part of my doctoral work, I investigated novel flight control laws that help pilots alleviate the rotor loads on current- and future-generation military rotorcraft while still meeting desired handling qualities. To bring such control laws closer to their actual implementation on production rotorcraft, I successfully developed and validated a novel methodology to identify Linear Time-Periodic (LTP) systems from rotorcraft flight-test data during an extended stay at the U.S. Army Aviation Development Directorate (ADD) at NASA Ames Research Center.

I am 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 am currently seeking a tenure-track faculty position at the assistant professor level in the broad area of flight dynamics and controls.
