Research Assistant Professor
Christos Papachristos



Christos Papachristos obtained his Ph.D. in the field of aerial robotics design, control, and autonomy from the University of Patras, Greece in 2015. Subsequently, from the promoted role of Post-Doctoral scholar, he continued his research in relation to the AEROWORKS (EC Horizon 2020) research project, leading the activities of aerial robotic development, control, perception and autonomous path planning.

After moving to the United States in 2016 as a senior postdoctoral researcher at the Autonomous Robots Lab of the University of Nevada, Reno, he focused his research on innovative systems and methods that promote autonomy, long-term reliability, and robustness of operation in unknown environments. He has since worked on both the technical side and the organization of several large multi-million dollar research projects on this side of the Atlantic, such as NRI: Multi–Modal Characterization of DOE–EM Facilities.

Christos Papachristos is currently a research assistant professor at the University of Nevada, Reno, and his research is dedicated to enabling operational resilience and autonomous exploration, mapping, and characterization of complex GPS-denied degraded visual environments that pose strict robotic requirements for austere navigation, degraded sensing, and severe communication and endurance limitations. In the same context, as a member of team CERBERUS that participates in the DARPA Subterranean Challenge, he is primarily involved with the technical leadership of the Micro Aerial Vehicle autonomy component and the Robotic Integration efforts for the competition.
