      This interdisciplinary meeting brings together leading experts working on dynamics problems in engineering and applied science. The workshop will focus on the theoretical areas of nonlinear dynamics and time delay systems with applications ranging from machine tool chatter through robotics to biological systems.

      The event is timed as a satellite conference of the European Nonlinear Oscillations Conference (ENOC) Vienna, Austria, July 6-11, 2014. From Budapest, Vienna is just a two-hour drive, or a 3.5-hour ride by train, or a six-hour scenic trip by boat on the Danube. (Travel tips to get to Vienna.)

      The meeting will also serve to celebrate the 60th birthday and career of Professor Gábor Stépán, a leader in the application of dynamical systems concepts to engineering problems.
      Gábor Stépán received his Ph.D. in 1982 and his D.Sc. in 1994 from the Hungarian Academy of Sciences. He spent most of his academic career at the Budapest University of Technology and Economics, where he has been the Chair of the Department of Applied Mechanics since 1995. He served as Dean of Mechanical Engineering between 2008-2012, and held visiting professorships at Newcastle University and the California Institute of Technology.

      Among his numerous research and teaching awards, Professor Stépán received the Charles Simonyi Engineering Prize (2007) and the Széchenyi Prize of the Hungarian Republic (2011). He was elected Full Member of the Hungarian Academy of Sciences (2007), and Associate Member of the International Academy for Production Engineering (CIRP, 2012). He has served on a number of editorial boards and professional committees, and advised a large number of successful Ph.D. students.

      Professor Stépán pioneered the use of delayed dynamical systems in engineering modeling and analysis. He is the author of the classic monograph Retarded Dynamical Systems (Wiley, 1989), and co-authored the book entitled Semi-Discretization for Time-Delay Systems (Springer, 2011) with Tamás Insperger. His research interests include machine tool vibrations, wheel and tire dynamics, robotics and force control, human and machine balancing, and vehicular traffic.
