Emeritus Professor of Engineering

Background:

Richard graduated from the University of Cambridge in 1979 with a first class honours degree in Engineering and was jointly awarded the Ricardo Thermodynamics Prize.  In his first job at Ricardo Consulting Engineers he worked on high compression ratio gasoline engines before helping implement one of the first heavy duty transient test beds.   Richard  joined Cambridge Consultants in 1984 working on a range of technical and product development projects, serving as consultant, department head and business development manager.  He took up his first academic post in 2001 as Professor at University of Sussex and moved to Loughborough in 2007 as Ford Chair then Chair of Powertrain Systems, working closely with Caterpillar as Technical Director of the joint research activity. 

Richard retired from his full time position in September 2016, and was appointed Professor Emeritus soon after.  He assists with teaching and supervision of PhD students, while continuing to develop research in the field of energy recovery. 

Qualifications:

  • MA (Hons) University of Cambridge
  • British Computer Society Part 2 Examination

Key Awards:

  • Ricardo Thermodynamics Prize, University of Cambridge
  • Fellow of the Society of Automotive Engineers

Outline of main research interests:

My primary research interest is in the thermodynamics of engines and their supporting systems.  This topic includes engine control, engine air and fuel management and the recovery of otherwise wasted energy from engine exhaust and coolant. 

The principal challenges in engine control lie in the translation of a control concept with strong theoretical underpinnings into a practical solution.  Modelling, control system design and digital implementation all have a role to play.  The adaptation of the control system to the practical application through the process of calibration includes a research challenge in the use of optimisation and statistical methods. 

My current research activity is centred on the use of solid state, thermoelectric methods for energy recovery from internal combustion engine exhaust flows.  New manufacturing methods will lead to lower cost solutions.  Deeper integration of thermoelectric generators will result in power generation to supplement the vehicle’s electricity supply and improved management of the thermal conditions in the exhaust and exhaust gas after-treatment systems.  

Grants and contracts:
