Principle Investigators

Dr Jun Chen (University of Lincoln)

Dr  Jun  Chen is a Senior Lecturer at the University of Lincoln and the lead PI for the overall project. He is active in the field of airport operations research since his involvement in the  EPSRC  funded  project  (EP/H004424/2).  He  has  published  over  30  papers  in  multi-objective optimisation,  interpretable  fuzzy  systems,  data-driven  modelling,  and  intelligent  airport  ground operations. He was among the first researchers to investigate the trade-off between taxi time and fuel  consumption  in airport ground  movements,  and  proposed  the  Active  Routing  (AR)  concept for  airport  ground operations,  integrating  aircraft engine performance and  airframe  dynamics  with routing and scheduling. He was the PI on numerous industrial projects with Anglian Water to develop intelligent pump control systems, and is currently the CI on an Innovate UK project on the development of dynamic energy control systems for food retailing refrigeration systems (with IMS and Tesco plc).

Professor Mahdi Mahfouf (University of Sheffield)

Prof Mahdi Mahfouf holds a Personal Chair in Intelligent Systems Engineering in the Sheffield University Department of Automatic Control and Systems Engineering. He has been active in research on modelling, control and optimisation for more than 29 years with more than 300 publications, half of these being journal papers. His research expertise lies in modelling uncertainties of large-scale nonlinear systems while reconciling accuracy and transparency and developing new algorithms for multi-criteria decision-making for convex/non-convex problems with an emphasis on economic and societal impact. This is invaluable to the proposed project in identifying unstable regions during aircraft ground maneuvering. He has received several paper prizes and research awards for building successful synergies between systems and control engineering principles and life sciences as well as industrial systems.

Dr John Woodward (University of Stirling)

John Woodward is currently a lecturer at the University of Stirling. His research interests include artificial intelligence, machine learning, and more specifically the automated design of algorithms including meta-heuristic and hyper-heuristic approaches. He currently jointly hosts a workshop at Genetic and Evolutionary Computation Conference (GECCO) on the automated design of heuristics and algorithms.

Dr Mudassir Lone (Cranfield University)

Dr. Mudassir Lone is a Lecturer at Cranfield University. He received his BA and MEng degrees from Cambridge, and PhD from Cranfield. His research interests include aircraft stability and control, aeroelasticity, simulation and modelling, and aircraft flight testing. His experience in designing and conducting piloted trials is highly relevant for evaluating the methodologies proposed in TRANSIT. He is a professional member of AIAA and has served on the AIAA Atmospheric Flight Mechanics Technical Committee since 2010. Part of airline pilots for trial studies in this project will be sourced through his link with National Flying Laboratory Centre (NFLC), in particular through Dr. Jim Gautrey (Head of NFLC).

Dr Michal Weiszer (University of Lincoln)

Michal Weiszer  is a Research Fellow at the University of Lincoln. He worked on integration of airport ground movement with runway scheduling, multi-objective optimisation and real-time routing for taxiing aircraft (EP/H004424/2). Research methods include metaheuristics, multi-objective optimisation, decision support and other problem solving heuristics.

Dr Alexander Brownlee (University of Stirling)Sandy Brownlee

Alexander Brownlee is a Senior Research Assistant at the University of Stirling. He received his PhD from Robert Gordon University in Aberdeen 2009. He then worked as a software engineer in industry, and a research associate at Loughborough University before moving to Stirling. Dr Brownlee’s current research interests are in the area of “value-added optimisation”; techniques which yield optimal or near-optimal solutions but also reveal underlying information about the problem to better support decision making. His main focus is in metaheuristics, including evolutionary algorithms and estimation of distribution algorithms; related issues such as fitness modelling (and mining such models), handling constraints and multiple objectives, and decision support; and application areas including scheduling and simulation-based optimsation in civil engineering and transport.

Dr Olusayo Obajemu (University of Sheffield)

Olusayo Obajemu is currently a research associate with the department of Automatic Control & Systems Engineering at the University of Sheffield. He received his  PhD degree  from the University of Sheffield in 2016 where he worked on dynamic risk modelling and management of patients diagnosed with bladder cancer. He received a masters degree with distinction from the University of Sheffield and his masters thesis was in developing optimal  models and schedules  for the hot rolling of steel process. He has interests in machine learning, survival analysis and computational intelligence methods for decision support in aerospace, healthcare and materials science.
