Current activities


Leads the development of Techno-economic Environmental Risk Assessment (TERA) frameworks for simulation of integrated conventional and advanced aircraft and power plant system concepts (including Hybrid-electric propulsion and  Hydrogen  fuel system design and integration)

Leads the development of the following research software for the Centre:

Integrated Aircraft and Propulsion System Performance

Environmental policy assessment and economics models to assess civil aircraft profitability and operational effectiveness (Optimised Trajectory/ mission assessments, Cost Index Methods, investment viability assessments)

Contrail prediction and assessments integrated with aircraft performance tools

Technical project management

Serves as principle investigator, co-principle investigator and research point contact on EU and international projects related to aeronautics and propulsion

Provides specialist support within the centre and represent the centre as subject expert on propulsion related topics at technical project meetings within the United Kingdom and  internationally

Supervised to completion 10 PhD researchers and 78 MSc students and currently manages a team of 1 Research Fellow, 6 PhD researchers and  3 MSc students

Supports centre’s capabilities in advanced predictive modelling and simulation for integrated aircraft and power plant concepts, to enable:

o    Design space exploration

o    Performance optimization of aircraft and novel power plant systems

o    Estimation of environmental performance

o   Estimation of operating cost (including component life estimation, power plant maintenance costs and cost index based assessments)

o    Estimation of investment viability of power plants
