Research overview
My research interests are on pollutant removal and nutrient recovery from effluents and waste water (biofiltration), using constructed wetland systems, and on the production of biomass crops.
Research focussed initially on wetland beds planted with reed and willow for landfill leachate treatment. Field studies involved the novel use of membrane-inlet mass spectrometry (developed at Cardiff University) for in-situ measurements of dissolved gases to monitor spatial and temporal changes in the sub-surface environment of a tidal flow willow bed. This technique is now being applied to mesocom tanks planted with reed and willow to monitor N removal capability in low-oxygen, low-redox, inundated environments. Micro-electrode measurements of oxygenation by the roots of individual willow and reed plants in laboratory systems demonstrate the capacity of these plants to modify the rhizosphere environment, and highlight their essential role in the process of N removal by the microbial community in biofiltration systems.
I am also interested in developing low-input regimes for production of short rotation willow coppice and biomass grasses in marginal uplands of Wales and implications for land use and conservation.

Current research interests
Pollutant removal and nutrient recovery from effluents and waste water (biofiltration), using constructed wetland eco-technology
Testing a novel recirculation system with willows, planted in a tidal flow tank (mesocosm) to remove pollutants from landfill leachate effluent
Biofiltration of effluents in constructed wetland systems
Constructed wetlands (CW) planted with reed and willow and acting as biofilters, provide a cost-effective method of pollutant removal and nutrient recovery from waste water and other effluents such as landfill leachate, avoiding the risk of local pollution of water-courses. Field studies using the novel technique of membrane-inlet mass spectrometry (MIMS – developed at Cardiff School of Biosciences by Prof D. Lloyd) demonstrated the role of willow roots in oxygenating the sub-surface environment of a tidal-flow willow bed. MIMS enables in situ measurements of in dissolved gases (e.g. O2, CO2, NH3, CH4) in the undisturbed sub-surface environment. These gases act as indicators of spatial and temporal variation of microbial activity. This technique is now being applied to mesocom tanks planted with reed and willow to monitor N removal capability in low-oxygen, low-redox, inundated environments. Micro-electrode measurements of oxygenation by the roots of individual willow and reed plants in laboratory systems demonstrate the capacity of these plants to modify the rhizosphere environment, and highlight their essential role in the process of N removal by the microbial community in biofiltration systems.

Previous research activities
Biomass production with short rotation coppice and energy grasses
Willow coppice for biomass.
High production willow and biomass grasses are feasible as alternative crops in marginal farmland areas, such as the uplands of Wales. Research over 20 years into planting and management regimes for biomass crops and into habitat enrichment in plantations was based at the University's Field Centre in Powys, mid-Wales. As alternatives to fossil fuels for heat energy and potentially biofuel feedstock, such crops offer additional income for farmers and diversity in the landscape.

- Prof P Kowalik (Technical University of Gdansk, Poland)
Enzymic extraction of ethanol from plant biomass and cellulosic waste materials
Degradation of cellulose to simple sugars enables the production of ethanolic biofuel from biomass grass crops or plant waste residues. Research into the practical and economic feasibility of utilising low cost feed-stocks was aimed at developing novel enzyme systems to optimise ethanol yield.

Computer simulations for teaching in biosciences
Computer simulation models can provide valuable insight into the functioning of biological systems both as experimental tools and as teaching aids. Following earlier simulations in genetics, we developed a simulation model of the trophic dynamics of an aquatic ecosystem for ecology teaching (program available on request).
