Dr David Wall


Dr David Wall is a Lecturer in Transportation at UCC and a Funded Investigator in the SFI MaREI Centre for Energy, Climate and Marine. Prior to joining UCC as a lecturer, David obtained a Teagasc Walsh Fellowship PhD, and a Masters in Biosystems Engineering from Michigan State University, US. David has also previously worked as a process engineer in the UK. David has published over 40 peer reviewed journal papers in the research area of circular economy, energy and environmental systems. David is an Irish delegate for the International Energy Agency (IEA) Bioenergy: Task 37 and has previously authored three IEA Bioenergy reports. David is also a committee member of the Irish Transport Research Network (ITRN). 

Research Interests
