  • Ph.D. in “Model-based fault diagnosis in rotor systems using self-sensing piezoelectric actuators”, Technische Universität Darmstadt, Germany, 2016.
  • M.Sc. in Automotive engineering, RWTH Aachen University, Germany, 2012.
  • B.E. (Hons.) Mechanical engineering- Birla Institute of Technology and Science, Pilani, Goa campus, 2008


Dr. Ambur began his education in India where he graduated B.E.(Hons.) from BITS-Pilani, Goa in 2008. After a brief stint for an year in Mercedes-Benz Research and Development India, he moved to Germany for pursuing higher education. He completed his M.Sc. Automotive Engineering from RWTH Aachen University and subsequently completed his Ph.D. successfully from TU Darmstadt, Germany. He joined Loughborough university, UK as a Research associate in July 2017 and now continues the same assignment at University of Birmingham since July 2018.


Research interests

  • Research interests of Dr. Ambur lie in areas of mathematical modelling, system identification, system engineering and control systems.
  • His doctoral thesis titled “Model-based fault diagnosis in rotor systems using self-sensing piezoelectric actuators” encompassed the areas of fault detection, parameter estimation and grey-box modelling approach. As a part of this research he worked at a rotor testrig with piezoelectric actuators and used these actuators for sensing using its self-sensing capability.
  • Earlier he also worked with projects involving Black-box modelling using neural networks, Model-predictive control, Automotive suspension systems and Software-in-loop testing for Automotive Transmission control unit (TCU) testing.

Current projects

Dr. Ambur performs multi-body (vehicle) dynamic simulation, railway track dynamics and vehicle-rail interaction related tasks for conventional and novel concepts of switches and crossings.

The current project (S-CODE) on novel switch and crossing design for railway tracks is funded by the European Commission under their Shift2Rail  initiative.
