Andrew is an Associate Professor in Engineering.

Andrew is currently the Principal Investigator on the £2.5m EPSRC funded CCSInSupply project and a Research Investigator on the £25m Centre for Energy Systems Integration (CESI). He is a co-Investigator on the EPSRC Network for Hydrogen Transportation (Network-H2) and A Zero-Emission Closed-loop linear-Joule CYcle (ZECCY) project on hydrogen energy converters.

He is has also been an Investigator on Innovate UK projects on a free-piston engine range-extender and a H2020 project (H-DisNet) on a thermo-chemical district heating networks.

Previously Andrew was Chief Technical Officer at CMCL Innovations in Cambridge and was responsible for developing multiple engineering software simulation tools currently used worldwide for internal combustion engine and future fuel development.

Andrew graduated from the University of Southampton in 1999 with a Mechanical Engineering degree. He then completed an M.Sc. in Combustion and Energy and then a PhD from the University of Leeds. Andrew then went on to a Post Doctoral Research Fellowship at the University of Kyushu, Japan at the 21st Century Center of Excellence. He then went on to be Research Staff at Princeton University, U.S.
