Ashwin Krishnan
Ashwin Krishnan is a Ph.D. Student in the Guggenheim School of Aerospace Engineering at Georgia Tech. He has always been fascinated by all physical phenomena and how masterfully manipulating them can lead to engineering marvels. He picked up a B.S. degree in Aerospace Engineering in 2016 and a M.S. degree in Aerospace Engineering in 2018. Both from Georgia Tech, of course. His current research efforts include airborne wind energy harvesting and the suppression of helicopter ground resonance using active (robotic) landing gear. When he isn’t trying to push the limits of autonomous robotic systems, he can be found hiking, biking, camping or kayaking in the great outdoors with his brother, Arjun. Also, he wrote this entire bio in the third person.

Luke Heyerdahl
Luke Heyerdahl is an M.S. Student in the Guggenheim School of Aerospace Engineering. He received a B.S. degree in Aerospace Engineering from Georgia Tech in 2020. His current research investigates the effects of a bent-frame on the flight dynamics of a quadcopter. He has built a simulation environment in C++, which includes a dynamic inflow model for the quadcopter, waypoint-based navigation, and a Nonlinear-Dynamic Inversion controller. A flight path is generated from the waypoints, and the simulation determines the maximum tracking error of the quadcopter from that flight path for a given amount of damage. In his free time, Luke enjoys reading, gaming, watching baseball, and going out with friends.
