Expert's areas of expertise include Analytical Chemistry, Rheology, Tribology, and Computational Chemistry. He has experience in Vacuum Systems and Vacuum depositions and surface chemistry. Expert is working with STLE as subject matter expert in lubrication fundamentals.

Expert received a Ph.D. degree in Physical Chemistry from Case Western Reserve University in Cleveland, OH studying the surface reactions at fuel cell electrodes using molecular orbital methods under the guidance of Dr. A. B. Anderson. He received an M.S. degree in Chemical Engineering also from Case Western Reserve University where he studied the characteristics of “Diamond-like films” with his advisor Dr. John C. Angus. From Youngstown State University he received an M.S. degree in Chemistry using infrared spectroscopy to study surface electrochemical reactions under Dr. Daryl Mincey. He also received a BE degree in Chemical Engineering from Youngstown State University.

Currently a freelance consultant to the chemical, Tribology, and lubrication industries and freelance digital copywriter in the STEM disciplines. He continues his association with Employer as a visiting scientist. He began his employment with Employer as a Research Scientist in an “Open Innovation” collaborative effort between Employer and The Timken Co. in 2011. He is also currently a part time Senior Lecturer in the College of Applied and Science Technology. In his research position, in the Timken Engineered Surfaces lab and the Center for Surface Engineering and Lubrication Research he carries out fundamental studies of lubrication additives and lubrication mechanisms with an emphasis on quantum modeling, rheology, and high-pressure properties. Previously he worked at The Timken Company as a Product Development Specialist for lubricants and lubrication. He then moved to a position as a Tribological Specialist within the Tribology and Next Generation Materials group at the Timken Technology Center in North Canton. At Timken he studies how the chemistry of lubricants affects bearings especially how additives can be used to extend bearing life. Before coming to Timken he managed a polymer analytical chemistry lab at the Packard Electric division of DELPHI. He started at Packard Electric as a quality control engineer in the ignition cable department when Packard Electric was a division of General Motors. He was a Process Engineer on the thin film deposition processes for liquid crystal display products at PanelVision in Pittsburgh. Expert worked as a Research Engineer at The General Tire Company in Akron studying polymer extrusion and molding and the performance of tennis balls. He started his lubrication career as a Summer Intern at The Penn State University.

Expert has received a Professional Promise Award from AIChE and the Shell Lubricants award for Instructor Excellence from NLGI. Expert is a member of STLE, ACS, SOR, ASTM and MENSA.
