Dr. Jude A. Osara is an assistant professor in the Surface Technology & Tribology (STT) and Tribology Based Maintenance (TBM) research areas in the department of Mechanics of Solids, Surfaces and Systems (MS3). He obtained his PhD in Mechanical Engineering - Thermal/Fluids Systems at the University of Texas at Austin, Texas, USA, with a dissertation on "degradation thermodynamics", an approach he applied to lubricant grease degradation and general fatigue, among others. Prior to his PhD degree, Jude worked in the automotive industry as a thermal/fluids engineer optimizing engine performance, and as an applied mechanics engineer analyzing/optimizing lubrication and structural integrity of engine overhead systems. Between 2017 and 2020, Dr. Osara ran his technology start-up EnHeGi, a platform on which he further developed his PhD research discovery into engineering analysis tools for industrial use, while doing stints as a post-doctoral fellow and an adjunct professor at the University of Texas at Austin. At UT Austin, Dr. Osara taught Applied Thermodynamics and Fluid Mechanics. Currently, he teaches Tribology, and his research focuses on bearing grease and solid interfacial degradation, life models, failure mechanisms, and materials, all of which he applies his thermodynamics expertise to. Dr. Osara also manages the SKF University Technology Center (UTC) for grease lubrication.
