Staff Profile

Professor Ian Postlethwaite

Deputy Head of Engineering

Background


Professor Ian Postlethwaite joined Newcastle University in February 2015 as Director of Corporate Projects. In that role he supported the Faculty and cross-cutting PVCs on projects of strategic importance to the University. In 2016 he became Dean (Singapore) moving to Singapore and taking on the roles of CEO for NUInternational Singapore Pte Ltd (NUIS) and CEO for Newcastle Research & Innovation Institute Pte Ltd (NewRIIS). In 2019 he returned to Newcastle and is now Acting Deputy Head of the School of Engineering.

Ian read Electrical Engineering at Imperial College and completed a PhD in Control Engineering at Cambridge. He held posts at Cambridge and Oxford before accepting a Chair in Engineering at Leicester University, age 34. At Leicester he was Head of Engineering, Pro-Vice-Chancellor (External Affairs) and Pro-Vice-Chancellor (Research), moving to Northumbria University as Deputy Vice-Chancellor in 2010.

His research involves theoretical contributions to the field of robust multivariable control and the application of advanced control system design to engineering systems. He is interested in the underlying principles of control and how they can be used to develop, from a strong theoretical foundation, practical design methods for practising control engineers. He has held visiting positions at the Australian National University and the University of California at Berkeley, and made many shorter visits to major research groups such as MIT, UC Santa Barbara, Tsinghua and Trondheim.

He is a Fellow of the Royal Academy of Engineering, the Institute of Electrical and Electronics Engineers, the Institution of Engineering and Technology and the Institute of Measurement and Control: FREng, FIEEE, FIET, FInstMC.

He has published more than 430 refereed papers and co-authored 3 graduate textbooks, including the highly regarded Multivariable Feedback Control (Wiley, 1996 and 2005), which has received more than 8000 citations (Google Scholar).

He has supervised 23 successful PhDs and co-supervised 15. He has received more than £7 million for his research from EPSRC, BBSRC, ESA, the EU, Government and Industry, and he did this when grants were relatively small. This includes two EPSRC Platform grants, which are special awards for world-class groups.
