James Murphy

Research Profile

James has a B.Sc. (Hons) degree in Cell & Molecular Biology from University College Dublin and a PhD in computational biology from the Centre for Scientific Computing and Complex Systems Modelling in Dublin City University. His research background involves developing theoretical approaches to model biological population dynamics. These can range in scale from the microscopic (e.g. bacterial cell interactions with antibiotics) to the regional scale (invasive species dynamics in the marine environment). They share in common the application of complex systems theory to understand how population behaviour emerges from dynamic interactions at the individual level.

His current research project POLLIVAL (led by Dr. Jane Stout and funded by the Irish Environmental Protection Agency) involves developing and assessing methodologies to evaluate pollination services in an economic context. Pollination is a vital ecosystem service provided by many different species of animals including honeybees, bumble bees, and other insects, as well as some birds and mammals. It plays a vital role in many aspects of our agricultural and horticultural industries, as well as in terms of supporting and regulating healthy ecosystems and maintaining biodiversity.

Assessing ‘natural capital’ and the ecosystem services which flow from it are key national environmental research priorities for the EPA. By understanding and communicating the total value of key ecosystem services, such as pollination, the research team will develop a better appreciation of natural capital for policy and planning decisions at many levels and across several sectors.
