I am an interdisciplinary researcher using systems approaches to ecological, biological & environmental problems. My subject specialism is Complex Systems Modelling which is underpinned by expertise in applied physics, 3D graphics & visualisation, statistics and programming. I have applied this expertise to develop models of biophysical and socio-economic-environmental systems. Interactive visualisation is a key tool for understanding complex systems and is interfaced to the developed computational models to characterise system dynamics and communicate complex technical information to specialists and non-specialists. I also co-lead the interdisciplinary Sustainability Assessment, Visualisation and Enhancement (SAVE) research group. Some areas of interest are outlined below.
Interactive Visualisation of Environmental Systems
Many contemporary problems are interdisciplinary in nature and involve many disciplines and stakeholders. Interactive visualization is a key component to support knowledge discovery, decision making and knowledge exchange. I have applied interactive visualisation to fundamental, knowledge exchange and policy facing research often developing bespoke tools based on computer games technology and engines.
Modelling and Visualisation for Fungal Ecology
A physiologically based reaction-diffusion model describing fungal growth and interactions has been developed to better understand the role of individual fungi in shaping community dynamics which has implications in soil decomposition, food spoilage and Sustainable Urban Drainage Systems. In simple environments (agar plates) the model permits the interpretation of macroscopic patterns in terms of microscopic mechanisms, and this model has been applied to soil ecosystems in order to translate micro-scale soil processes to macro-scale soil properties, with relevance to ecosystem services and larger biogeochemical cycles.
Recently the model has been applied to quantifying the effect of Particulate Organic Matter (POM) distributions on soil respiration induced by fungi. Results indicate that fungal growth is highly non-linear and variable and, at given average nutrient concentrations, strongly dependent on the micro-scale POM distribution. Experimental data on C-CO2 derived from POM and SOM decomposition of fungi were obtained from soil samples which differed in POM abundance, POM size and bulk density. This data will be used to calibrate the model and generate hypotheses regarding the role of fungi in soil POM decomposition.
Currently we are using this model to explore grain spoilage and mycotoxin production.
