Much of his work focused on vehicle structure design/optimization, vehicle NVH test and development, CAD/CAM/CAE, and engineering consulting on design methodologies. Designing new vehicle structures, he registered many patents and utility model patents in the USA, Europe, Japan, and Korea. He also received an “Innovation and Achievement Award” from ArvinMeritor, Inc., a "Best Paper Award" from the International Symposium on Advanced Material and Mechanical Application, an "Outstanding Presenter Award" from the International Symposium on Green Manufacturing and Applications.
He has performed research and published in the areas of mechanical system analysis and design, noise and vibration, experimental sensitivity analysis, structural dynamics/health monitoring, diagnostics and prognostics of mechanical system, design optimization, biomechanics, and protective device/structure.
Dr. Yang currently teaches or has teaching interest in Engineering Graphics, Industrial Computer-Aided Design, Advanced Mechanical Design, Vibration and Acoustics, Dynamics, Experimental Structural Dynamics, and Automotive engineering.
Professor Aaron Alexander joined the MET faculty in 2012 after spending more than a decade in industry. He obtained his B.S. in Engineering from Messiah College in 1999. After earning an MS in Mechanical Engineering from Purdue University, he worked as an Acoustical Engineer creating silencer designs for gas turbine duct work. He would later work as a Manager of Research and Development.
Professor Alexander is currently teaching the Basic Instrumentation, Applied Fluid Mechanics, Computational Fluid Dynamics, and Senior Design classes.
His interests include wind energy, noise control, CFD, general fluids, and helping his wife raise their two kids.
Richard A. Beier is a professor in mechanical engineering technology. He received a Ph.D. from the University of California, Berkeley, as well as B.S. and M.S. degrees from Kansas State University, all in mechanical engineering. Early in his career he taught within the School of Engineering Technology at the University of Nebraska at Omaha.
Prior to coming to OSU in 2000, he acquired 18 years of industrial experience with Conoco Inc., the DuPont Company, and Factory Mutual Research at locations in Oklahoma, Delaware, New Mexico, Texas, and Massachusetts. While at Conoco he worked as a reservoir engineer in research, technical service, and operational positions. Much of his worked focused on describing the flow of natural gas and oil through heterogeneous rocks. While a member of DuPont's process engineering group, he applied heat transfer principles in designing of a wide variety of equipment in the chemical processing industry. His contributions at Factory Mutual Research were in the area of fire research.
He has performed research and published in the areas of petroleum reservoir engineering, radiation heat transfer, convection heat transfer, fire research, combustion, ground-source heat pumps, building cooling loads, and applications of fractals.
Professor Beier currently teaches Thermal Fluids Lab (MET 4463), Basic Basic Thermodynamics (MET 3343), and Heat Transfer (MET 4433).
Professor Chang received his B.S. degree in Aeronautical Engineering from Hankuk Aviation College in South Korea, M.S. degree in Production Engineering from Korea Advanced Institute of Science & Technology, and Ph.D. degree in Mechanical Engineering from Oklahoma State University.
Before joining the Department of Mechanical Engineering Technology in 2000, he taught at the School of Mechanical and Aerospace Engineering at Oklahoma State University for six years. Professor Chang was affiliated with Web Handling Research Center at Oklahoma State University as research staff for thirteen years. His prior work experience was with the Ship Research Station of Korea Institute of Machinery & Materials, and Korea Atomic Energy Research Institute. His research areas include vibration of nuclear fuel rods, flow-induced vibration of heat exchangers and ocean structures, flutter of thin films, air-flotation and guidance of thin films and glass, and protective gears and garments.
Dr. Chang teaches MET 3003 Dynamics, MET 2313 Fundamentals of Hydraulic Fluid Power, MET 3413 Fundamentals of Pneumatic Fluid Power, and MET 4313 Electrohydraulic and Motion Control.
His personal interests and activities include shooting sports and serving on committees and organizations that promote the welfare of international students.
Warren Lewis started his career at OSU in 2001 after working seven years in industry. He held positions at The Charles Machine Works (Ditch Witch) and Central Machine and Tool.
Warren earned a Master's degree in Manufacturing Engineering Technology from University of Southern Mississippi in 1994. He is a 1991 alumni of the Mechanical Engineering Technology program at Oklahoma State University, and was awarded an Associate's degree from OSU-Okmulgee in 1989.
