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.

  Hydro-BPT - Towards a More Sustainable System of Water Supply in Ireland and Wales: Exploring Opportunities for Hydropower in Break Pressure Tanks
  Summary

  This project will advance the sustainability of the process of water supply in Ireland and Wales by exploiting the potential for energy recovery that exists at Break Pressure Tanks (BPTs). Water supply is a core service on which civilised society depends and it involves considerable energy consumption and CO2 emissions (water treatment, pumping and monitoring).

  Improving the Smart Control of Air Pollution in Europe (iSCAPE)
  Summary

  Website: www.iSCAPEproject.eu Twitter:iSCAPE_project The iSCAPE project works on integrating and advancing the control of air quality and carbon emissions in European cities in the context of climate change through the development of sustainable and passive air pollution remediation strategies, policy interventions and behavioural change initiatives. It tackles the problem of reducing air pollution impacts, focusing on the use of "Passive Control Systems" in urban spaces, on policy intervention and behavioural changes of citizens lifestyle. Projections and real-world physical interventions will be applied on the urban tissue in the selected cities assessed for future climate change scenarios and representative of different cultural & lifestyles in Europe.

  Reducing Energy Dependency in Atlantic area Water Networks (REDAWN)
  Summary

  Project 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.

  Summary

  Project 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.

  WOW! Wider business Opportunities for raw materials from Wastewater
  Summary

  The 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.

  GOGREEN ROUTES: Resilient Optimal Urban natural, Technological and Environmental Solutions
  Summary

  GOGREEN 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.

  Summary

  The 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.
