Argonne National Laboratory

Aaron Greco

Principal Materials Scientist

Aaron Greco is Principal Investigator on a project designed to improve the reliability of wind turbine drivetrains. The team accomplishes this through systemic investigation of field failures, such as surface contact failures of bearings and gears, and through laboratory testing of material and lubricant technologies to mitigate failures. Greco also supports research efforts to improve the fuel efficiency of vehicles through the development of various lubricant and surface treatment technologies to reduce frictional losses.

Greco has more than 10 years’ experience in the field of tribology and advanced surface engineering, specifically as it relates to vehicle and wind turbine drivetrains. His research interests include advanced surface treatments, nanoparticle lubricant additive technology and rolling contact fatigue. Greco recently completed a 15-month assignment at the U.S. Department of Energy headquarters within the Wind and Water Power Technology Office, where he provided technical management support to team leadership. Prior to joining Argonne, Greco was a Science and Technology Policy Fellow at the National Academies.
