Hanspeter Dinner
Owner
After completing my studies in mechanical and biomedical engineering at the Swiss Federal Institute of Technology (ETH) and the National University of Singapore (NUS) in 1996, I worked for three years as an FEM engineer. My work focused on welded structures and fatigue rating of safety-critical components and structures.
At KISSsoft AG - A Gleason Company, I started as a support and project engineer, where strong results in and a talent for market development led to promotion to Head of Sales.
In 2008, I founded my own gear consultancy firm and built up KISSsoft business in Asia as representative. As consultant, I completed about a hundred FEM, gear, rolling and slewing bearing, and transmission projects.
During my second tenure at KISSsoft AG as Sales Director and Managing Director, I contributed to the global reputation, worldwide partner network development, and growing sales of KISSsoft software.
Since May 2026, I work as independent gear consultant globally. Expertise ranges from gear geometry, plastic gear optimization, bearing analysis using MESYS to wind turbine main gearboxes. A partner network covering topics like FEM, CAD works, heat treatment expertise and dynamic analysis allow handling of complex projects.
Hanspeter will be presenting their paper on the “Flexpin for highest torque density in planetary gears, an application in a wind turbine main gearbox” at GEARS 2026
Oliver Fazzio
PHD Student
Oliver Fazzio is a PhD student in the Tribology Group in the Department of Mechanical Engineering at Imperial College London. He holds a MEng degree in Mechanical Engineering also from Imperial College London. His MEng project investigated the use of liquid droplets as supporting elements in a novel MEMS bearing. His current research combines surface metrology and contact mechanics alongside a novel test method to isolate the effect of roughness on scuffing failure in lubricated rolling-sliding EHD contacts.
Oliver will be presenting their paper "The Effect of Surface Roughness on Scuffing Damage in Rolling Sliding Contacts" at GEARS 2026
Caio Gomez
PHD Student
Caio Gomes holds the degrees of Mechanical Engineering (2020) and Master of Science (2023) at the Aeronautics Institute of Technology (ITA).
He is currently a Research Assistant and PhD Student at ITA's Competence Center in Manufacturing (CCM-ITA) and a member of the Gear Innovation Group (GIE) in Brazil.
His research interests are related to the influence of manufacturing processes on the gear operational behaviour, with a focus on the induced surface integrity state and its correlations with gear failures.
Caio will be presenting their paper "Residual stress heterogeneity effects in gear bending fatigue lifetime" at GEARS 2026
Daniel Hall
Research Engineer
Daniel Hall holds a BEng and MSc in Mechanical Engineering. His presentation “A feasibility study into the modification of a power recirculating gear test rig, to allow investigation into the influence of reverse bending in gears.” was completed as part of his final project during his MSc, working in partnership with Design Unit, Newcastle University. Following the success of the project and a five-month internship, Daniel now works full time at Design Unit as an Assistant Research Engineer.
Daniel will be presenting their paper "A feasibility study into the modification of a power recirculating gear test rig, to allow investigation into the influence of reverse bending in gears" at GEARS 2026
Bahadir Karba
PHD Student
Bahadır Karba is a PhD Candidate in Mechanical Engineering at Bursa Uludağ University, Türkiye, and Reducer Mechanical Design Leader at Valeo. His work focuses on functional transmission accuracy, precision gearing, bearing–shaft–housing systems, drivetrain positional accuracy, and virtual transmission testing.
His MSc research investigated backlash prediction and reduction in planetary gearboxes, considering manufacturing and assembly deviations, component matching, and low-backlash assembly methodologies. His doctoral research extends this work toward the tribological and positional behaviour of Gear–Bearing Drive systems under cryogenic conditions, with particular emphasis on integrated position error, transmission error, backlash, bearing-support effects, manufacturing tolerances, thermal variation, and phase-resolved positional accuracy.
His broader research includes Integrated Position Error (IPE), Integrated Bearing Position Error (IBPE), Functional Shaft Position Error (FSPE), probabilistic transmission-error modelling using single-flank test data, and virtual gear-testing methodologies linking design, manufacturing, metrology, and drivetrain performance. His industrial work includes e-drive gearbox and reducer development, gear design, NVH, manufacturing quality, and drivetrain precision.
Bahadir will be presenting their paper "Integrated Bearing Position Error and Functional Shaft Position Error: A Deterministic Positional Transmission Framework for Bearing Shaft-Housing Systems" at GEARS 2026
