Modelling and Informatics

Cross-Thematic Activity Team Leader: Dr. Jim Duggan

Modelling & Informatics is a research activity that is common to many research fields.  Within the Ryan Institute Modelling & Informatics is structured as a cross-cutting activity interfacing with all of the research thematic areas.

Environmental systems modelling is an activity in which environmental processes are represented as simply as possible by mathematical and physical scale models. Modelling physical, biological and chemical processes has become central to developing a more detailed description of the environment and its management.  Modelling complements field based marine and terrestrial research by providing predictions of complex systems and processes such as:

    • Marine processes: hydrodynamics; biogeochemical cycling; surges and coastal flooding
    • Water quality modelling: radionuclides; heavy metals; phytoplankton; public health
    • Energy systems: marine renewables; smart buildings
    • Mathematical, statistical and physical scale modelling
    • Climate change modelling: global modelling; dynamic downscaling; Air-sea gas exchange
    • Waves and associated sediment transport
    • Deep ocean, estuarine, and coastal circulation

 

Informatics is concerned with the development and application of information communication technology to diverse problems.  In the Ryan Institute the focus is in integrating modelling and informatics with data and outputs from the various thematic areas.  Various informatics and communication platforms are used to integrate these strands: GIS, web technology; open source software; radars; wimax radio links.  This integrating approach provides research with platforms/tools to add value to independent datasets and to help improve predictive models.  This approach also brings research closer to the market place and more available to environmental mangers. Modelling and Informatics is a field that is critical to Environmental, Marine and Energy research, where data needs to be generated, processed, and visualized.

Modelling and Informatics researchers at the Ryan Institute have established excellent links with many national agencies such as Met Eireann, the Marine Institute, the Radiological Protection Institute, the Department of Environment, Heritage and Local Government, Enterprise Ireland, and the EPA.  Internationally, we have established strong links with research groups working in institutes such as Max Plank Institute (Hamburg), University of Cantabria (Santander), Ifremer (France), Cardiff University (Wales), University of Davis (California) and Instituto Superior Technico (Portugal).

I use modelling to visualize and trace the geographies of social and demographic change.  Current projects include: (i) examining the influence of neighbourhood effects on early school leaving in Ireland using GIS, spatial data analysis and multi-level modelling, and (ii) incorporating multi-level modelling to examine the educational attainment of migrant youth in Galway city.

Dr. Quinlan’s research interests are in fluid dynamics, with experimental and computational methods applied to renewable and conventional energy systems, among other areas. A speciality is the development of mesh-free methods (smoothed particle hydrodynamics and the finite volume particle method) for fluid dynamics. These approaches display unique advantages for the modelling of complex free-surface phenomena including breaking waves and wave-body interactions.
