Professor Colin Snape

Principle Investigator

With over 30 years of experience working on many aspects of carbonisation and solid fuels, together with biochar characterisation, Colin has led many EU, UK Government and research council projects including directing two Centres of Doctoral Training. He has played a prominent role coordinating energy research at Nottingham and across the Midlands universities, leading to the establishment of the Energy Research Accelerator in 2017 and now The Biochar Demonstrator.

Dr Jon McKechnie

Co-Investigator (LCA/TEA)

Jon’s research focuses on lifecycle assessment (LCA) and technoeconomic assessment (TEA) to inform the design and optimisation of sustainable energy systems.

Dr Disni Gamaralalage

Disni Gamaralalage obtained her doctorate from the University of Tokyo, Japan in 2019 where she worked as a project researcher for 3 years undertaking life cycle assessments related to biomass-based processes. She joined the Biochar Demonstrator at University of Nottingham, UK as a research fellow in 2022.

Dr Helen West

Co-Investigator (Agriculture)

Helen’s work involves biomass residues and nutrient dynamics including biochar effects on N2O and CO2 production following soil amendments, effects on crop growth, N fixation and kinetics. She has conducted field trials in the UK and elsewhere and has soil microbial and agronomic expertise.

Headshot of Tom Bott

Dr Tom Bott

Tom is a soil scientist and microbiologist who researches nutrient cycling in soil. He is working with biochar to see if its addition to soils changes nutrient cycling which might then have an impact, positive or negative, on crop growth and soil health.

Promise Simwinde Muleya

Promise is a senior technician based in the School of Biosciences, University of Nottingham, conducting a range of analytical techniques including soil and plant elemental analyses, DNA extractions and field sample collection. He completed his Master’s degree in Physical Land Resources (Soil Science) at Ghent University in Belgium and a BSc in Natural Resources Management and Agriculture (Agronomy Major) from his native Zimbabwe. He has worked on projects ranging from integrated food, nutrition and incomes security programmes in Zimbabwe, to trace elemental analysis in plants and soil for the Geo-Nutrition, BIZIFED, MAGNET and Clima-LoCa projects UoN.

Headshot of Paul Wilson

Professor Paul Wilson

Co-Investigator (Agriculture)

Paul is a Professor of Agricultural Economics and the Chief Executive of the Rural Business Research. He analyses trade-offs between net energy, financial returns and greenhouse gas emissions at the farm-level given different market, regulatory and policy scenarios; understanding farmer behaviour and attitudes toward growing dedicated energy crops, using co-products and toward different tillage techniques.
