Gear Dynamics and Gear Noise Short Course
(June 2 - 5, 2025)

About Us

The Gear Dynamics and Gear Noise Short Course will be taught by leading professors and researchers in these fields.
DR. RAJENDRA SINGH is the course organizer and directs the Acoustics and Dynamics Laboratory (mae.osu.edu/adl) at Ohio State as Academy (Emeritus) Professor.  He is well recognized for research in geared system vibration & noise, bearing-casing dynamics, gear rattle analysis and nonlinear driveline dynamics. Dr. Singh has lectured on many topics in the gear noise and dynamics short courses since 1979. Over the past 40+ years at Ohio State, he has published more than 500 articles, and has advised over 170 student theses. He is a Fellow of the ASME, ASA, SAE, and INCE/USA, and has received several national awards for both teaching and research.  Dr. Singh developed and taught an innovative graduate course sequence in automotive noise and vibration control in partnership with General Motors.  He has served as the President of the Institute of Noise Control Eng. in 2003. Also, he was the President of INTER-NOISE 2021 (the 50th congress). 
DR. AHMET KAHRAMAN is the Winbigler Designated Professor of Mechanical and Aerospace Engineering at the Ohio State University. He is the Director of the Gear and Power Transmission Research Laboratory (GearLab). He also directs Pratt & Whitney Center of Excellence in Gearbox Technology. He received his Ph.D. degree in Mechanical Engineering from Ohio State in 1990. He worked for General Motors for 10 years before moving to academia. His research focuses on several areas of power transmission and gearing including gear system design and analysis, gear and transmission dynamics, gear lubrication and efficiency, wear and fatigue life prediction, and test methodologies. He authored more than 200 papers on gear research. He was the past chairman of the ASME Power Transmission of Gearing (PTG) Committee and Chairman of the 2007 and 2009 ASME PTG Conferences. He was a former associate Editor of ASME Journal of Mechanical Design. He serves on the editorial boards of Journal of Sound and Vibration, and Journal of Multi-body Dynamics. He is a fellow of ASME.
DR. DAVID TALBOT is an Assistant Professor with the Department of Mechanical and Aerospace Engineering of The Ohio State University. He received his Ph.D. degree in Mechanical Engineering from Ohio State in 2012. His research focuses on multi-disciplinary power transmission problems within the aerospace, transportation, wind energy, and industrial gear box industries. His specific research investigations include load distribution modeling of power transmission components, gear, bearing and power transmission system efficiency modeling and measurement, gear dynamics and vibrations, and gear manufacturing process simulation. He is the Vice-Chairman of the ASME Power Transmission and Gearing Committee (PTG) and Program Chair of the ASME Power Transmission and Gearing Conference 2019. He also serves as the associate editor of Mechanism and Machine Theory.
DR. DONALD HOUSER is the founder of the gear noise and gear dynamics short courses and has lectured on many topics since 1978. He is Professor Emeritus of Mechanical Engineering and Founder of the Gear Dynamics and Gear Noise Research Laboratory at Ohio State.  He has been active in gear dynamics research for over 45 years and has served as a consultant for numerous companies.  Dr. Houser is past Chairman of ASME's Power Transmission and Gearing Committee, past Chairman of ASME's Gear Noise Committee, a member of AGMA Noise Committee, and author of gear noise chapters in Gear Handbook (D. Townsend, editor) and Handbook of Noise & Vibration Control (M. Crocker, editor).
DR. RAJENDRA GUNDA is the Director of Engineering at ANSOL (ansol.us). He is the developer of the Coustyx boundary element software used for acoustic simulations. He received his Ph.D. degree in Mechanical Engineering from Ohio State in 1998. He has published a number of scholarly articles in the area of dynamic systems and acoustics. He has more than twenty years of practical experience in the industry.

DR. ISAAC HONG is a Assistant Research Professor in the Gear and Power Transmission Research Laboratory (GearLab), part of the Department of Mechanical and Aerospace Engineering at The Ohio State University. He received his Ph.D. degree in Mechanical Engineering from Ohio State in 2019. In addition to supervision and management of the experimental laboratories at GearLab, his research efforts focus on theoretical and experimental evaluation of gear fatigue characteristics, as well as efficiency and dynamic evaluation of power transmission components and systems. Dr. Hong’s expertise includes gear fatigue, gear vibration testing methodologies, data acquisition, and signal processing. Dr. Hong also serves on the ASME’s Power Transmission and Gearing Committee.
JONNY HARIANTO is a Senior Research Engineer and Associate Director in the Gear and Power Transmission Research Laboratory (GearLab), part of the Department of Mechanical Engineering at The Ohio State University.  He has a Master's degree in Mechanical Engineering from Ohio State with a specialization in geared systems, and has co-authored several technical papers. Jonny develops, enhances and maintains widely used gear analysis codes for the GearLab, while handling the GearLab administration and acting as a liaison to over 75 GearLab industrial consortium members. He also provides the essential training for and support of the GearLab software to both consortium members and graduate students.
