Henning Jung, MSc, studied mechanical engineering at the University of Siegen. He is now a
research assistant working in the Applied Mechanics group of Professor Claus-Peter Fritzen at the
University of Siegen. His research activities are focussed on dealing with the development of modern
structural health monitoring systems (SHM) for railway vehicles. Prior to this, he also worked
as a research assistant in the field of rolling mill design at Achenbach Buschhütten.
Alexander Keylin is a senior engineer in the Vehicle-Track Interaction group at Transportation
Technology Center, Inc. (TTCI) in Pueblo, Colorado. He holds a BSc in mechanical engineering
from University of Pittsburgh (2011) and an MSc in mechanical engineering from Virginia Tech
(2012). His work involves testing and characterisation of rail vehicles, modelling of special track
work, conducting computer simulations of vehicle-track interaction, analysis of ride quality data
and development of algorithms for processing of rail profiles and track geometry data.
Adam Klopp is a senior engineer at Transportation Technology Center, Inc. (TTCI) in Pueblo,
Colorado, specialising in vehicle-track interaction and train dynamics. He has over 7 years of railroad
research and engineering experience at TTCI. His research includes the characterisation, analysis
and modelling of rail vehicles and trains. His testing experience includes static and dynamic
vehicle and track tests, compressive end load tests and impact tests. He holds a BSc in mechanical
engineering from Colorado State University (2012) and an MSc in engineering with emphasis in
railroad engineering from Colorado State University-Pueblo (2016).
Joerg Koch is employed at Knorr-Bremse-Systeme für Schienenfahrzeuge, Munich, Germany.
He has a university degree as Dipl.-Ing. in Mechanical Engineering. After university, he developed
and built a range of test rigs for railway equipment. He has been responsible for the ATLAS test rig
since 2010 and was involved in its concept, design, build, commissioning and now its operation.
Kirill Kyakk is executive director of PTK-Engineering LLC (Russia), the freight wagon fleet operating
company introducing next-generation freight cars and heavy freight trains on 1520 mm gauge
railways. He obtained the PhD in 2007 at Petersburg State Transport University in St. Petersburg,
Russia. His field of scientific interest is railcar design theory and system engineering. Dr. Kyakk has
16 years of experience in the railway industry, including leadership and participation in the development
of more than 120 new freight wagon models with improved technical characteristics for the
railways of Russia, Europe, Africa and the Middle East.
Roger Lewis is a professor of mechanical engineering at the University of Sheffield, where he
teaches design and tribology. He received his PhD from that university in 2000, before joining the
academic staff in 2002. His research interests are split into three areas: solving industrial wear
problems, application and development of a novel ultrasonic technique for machine element contact
analysis and design of engineering components and machines. He has worked on a number of projects
related to the wheel-rail interface, including understanding fundamental mechanisms and modelling
of wheel and rail materials, measurements of wheel-rail interface conditions and rail stress,
friction management and understanding of low adhesion. In 2019, he was appointed as a Royal
Academy of Engineering Research Chair in ‘Wheel/Rail Interface Low Adhesion Management’.
In collaboration with the Rail and Safety Standards Board, he will now undertake a 5-year programme
of work in this area.
Yaru Liang is a PhD student at the State Key Laboratory of Traction Power, Southwest Jiaotong
University, China. She received her bachelor’s degree in vehicle engineering at Dalian Jiaotong
University in 2010. She then continued her studies for the master’s degree course from 2010 to 2012
and later became a PhD student. Her research interests are in vehicle dynamics simulation and roller
rig testing.
