Research Expertise
My research interests and expertise focuses upon the delivery of innovative solutions to current environmental and energy challenges. I aim to ensure that my results/solutions do not have consequential impacts by looking towards the future as well as examining results from the past. This approach is considered in my research of passive air pollution controls, low carbon and resource efficient system design and innovation in the delivery of technological solutions for energy efficient systems. I approach research problems using the 3M Model (Measurement, Modelling and Mitigation), and use my experience in life cycle assessment and the circular economy to generate conclusions without negative consequences.

TitleReducing Energy Dependency in Atlantic area Water Networks (REDAWN)SummaryProject Website: www.REDAWN.eu Twitter: @RedawnAA Significant potential currently exists to save energy, reduce costs and minimise environmental impacts in European water networks by improving the energy efficiency of water suppliers and users in the region. REDAWN will develop both the technology and policy to realise this potential, and generate understanding to help overcome any technological, institutional and social barriers to exploitation. The project aims to develop an adequate institutional, social and technological environment to foster greater resource efficiency in water networks including irrigation, public water supply, waste and storm water, and process industry. It will adopt next-gen micro-hydropower energy recovery technology in built water networks in the Atlantic Area, including in Ireland, France, Spain, Portugal and the United Kingdom.Funding AgencyEuropean Research Development FundDate From01/09/17Date To31/08/20

TitleDistributing our Water Resources: Utilising Integrated, Smart and low-Carbon Energy (DWR UISCE)SummaryProject Website: www.DWR-UISCE.eu Twitter:@Dwr_Uisce Improving the efficiency of water distribution in Ireland and Wales is at the core of the project ethos. This wil lbe achieved by developing new low carbon, energy-saving technologies and services. We will trial energy recovery technologies (micro-hydropower, drain water heat recovery and smart network controls) at several demonstration sites in both countries before being launched on the market. We will build a capacity for innovation in the water industry through our cluster of organisations interested in sustainability in the water-energy nexus.Funding AgencyEuropean Regional Development FundDate From01/09/16Date To31/02/23

TitleWOW! Wider business Opportunities for raw materials from WastewaterSummaryThe WOW project aims to create a transition in the URBAN WATER CYCLE: from a linear approach which ends up as sewage, to a circular approach in which raw materials from sewage are recycled for biobased products. This reduces CO2-emmissions and use of natural resources. WOW! revealed market potential and interest in the 5 products which will be produced: PHA (a completely biodegradable bioplastic), bio-oil, acetic acid, biochar & biodiesel. Currently 2 Memoranda of Understanding (MOU) are signed by end-users interested in our products & techniques, and 4 in the process of getting signed. A resolution on removing legal barriers for circular use of raw materials from sewage was accepted by the North Sea Commission (covering more than 150 coastal regions) and discussed with EC in relation to harmonising EU law on circular economy and sewage.Funding AgencyEuropean Regional Development FundDate From01/09/2021Date To31/12/2023

TitleGOGREEN ROUTES: Resilient Optimal Urban natural, Technological and Environmental SolutionsSummaryGOGREEN ROUTES delivers a focus on 360-Health, building upon the reciprocal benefits gained from human-nature interactions, sustainable physical activity, engaged citizen science and pro-environmental behaviour. GOGREEN ROUTES will initiate a process of solution conceptions which will impact well beyond the timescale of the project. Individual behaviour and lifestyle choices contribute greatly to natural capital, ecosystem conversion and biodiversity loss. These impacts are projected to worsen as the size and wealth of the global urban population continues to increase. Thus, opening minds to a new wealth of possible solutions are essential for addressing health and environmental challenges. Urban green space is associated with a wide-range of health indicators explained by a) mitigation (e.g. improved environmental quality (EQ)), b) psychological benefits (e.g. increased resilience), c) enriched biodiversity (e.g. enhanced immune function), e) safety and social cohesion and f) increased physical activity.Funding AgencyEuropean CommissionDate From01/04/20Date To31/07/24

TitleSTATION-AIR: Investigating the impacts of urban railway STATION hubs on AIR quality in its environsSummaryThe overall objective of the STATION-AIR project is to support the effective management and mitigation of air pollution in the environs of large urban railways hubs in Ireland. To meet this objective the following specific objectives are proposed: i) compile and review the available information on best international practice for the assessment and management of air quality arising from large urban railway hubs; ii) apply this best practice to the Irish context considering several detailed case studies and pilot sites; iii) provide an assessment of the impact of large railway hubs in Ireland on localised air quality in residential and urban areas; and iv) develop recommendations for the mitigation of air pollution emissions contributing to transport related air pollution (TRAP) in the environs of urban railway hubs.Funding AgencyEnvironmental Projection Agency, Department of TransportDate From31/03/2022Date To31/09/2025
