Biography

I am a Lecturer/ Assistant Professor in Biogeography and Palaeoecology in ICARUS and the Department of Geography at Maynooth University, a post I have held since moving to Ireland from Wales in 2017. I am also Associate Dean for Teaching and Learning in the Faculty of Social Sciences.

After graduating from two undergraduate degrees spanning Ecology (Southampton Biology 1997) and Geology/Environmental Science (Open University Science 1998) I worked at the Centre for Ecology and Hydrology in Wallingford, Oxfordshire, where I assisted with the scientific management of national and international programmes, such as NERC URGENT and IGBP GCTE Focus 3 as well as the UNESCO MAB UK secretariat. I then moved to Scotland to undertake a PhD in palaeoecology. I graduated with a PhD from Stirling University. My PhD explored the palaeoecological history of the fantastic Glen Affric pine woods in Scotland. This research was applied to the management planning for the future of the pine woods, an area which forms an exemplar of rewilding for future forest sustainability. 

Following my PhD I worked as a researcher at the International Centre for the Uplands in Cumbria, where I gained interdisciplinary experience and developed my interest in social-ecological systems and resilience. The work was focused on the sustainable management of upland systems via information flow between research and land managers. Whilst working at the centre I developed conferences on sustainable upland management, resilience in the uplands and adaptation to climate change as well as workshops on various themes including barriers to innovative planning development in national parks.
In combination with my work at the Upland Centre and my palaeoecology research I realised that landscape management relied on very short timescales. Concepts of resilience and rewilding, dynamics and change were limited by static conservation management guidelines, and, likewise environmental benefits in agricultural management were target focussed and static.  I then developed a research project, with Professor Ian Whyte at Lancaster University which was funded by the Leverhulme Trust, investigating upland landscape change in the North West of England. In this project we examined post-medieval 
landscape change via palaeoecology and history and applied this to ideas of sustainable landscape management for the future. My research has helped shape the growing assertion that long-term ecological dynamics are important. It is important to realise that traditional land management was always shifting and that these layers of history still impact on the present ecology. 

During my time at Lancaster University I also taught on the adult education post graduate programme in the Centre for North West Regional Studies, contributing both a module on Ecology of the Lake District and to the field trip module. My research at Lancaster was followed by teaching posts at Liverpool John Moores University and in Wales, where I enjoyed developing and teaching a range of modules across conservation and environmental science. I love to get out in the field and teach practical sessions. I have taught on the Geography programme in Maynooth since 2017, covering biology and ecological sustainability subject areas as well as introducing the subject of palaeoecology via a new module. I am supposed to be on a break from teaching in my role as ADTL, but I am still teaching on the Biology with Geography field trip, co-teach on the Masters in Climate Change (Palaeoclimate module) and am just starting a new fourth year module in Advanced Palaeoecology for 2024/25. I try to use our wonderful Green Campus as much as possible for outdoor teaching. I am very interested in communicating about the importance of biodiversity and ecology for future sustainability. A liveable planet means maintaining a functioning, diverse and living planet.
 

I am currently working on several research projects and themes: 

  1. Understanding of the representation of biodiversity in pollen diagrams. This work focuses on pollen representation of herbaceous species and the grazing signal of coprophilous fungal spores. 
  2. Understanding the provenance and processes of change in ancient woodlands. In which I have been working with Dr John Devaney from Biology among others to develop a new report on ancient woodlands for National Parks and Wildlife Service. Following this we have started a DAFM and NPWS funded project "Ancient Woodlands Ireland", to expand this research.
  3. Developing site histories for peat bogs in Ireland for community education and development in which I contributed palaeoecological information from a study at Lullymore to the Biodiversity Boardwalk info panels at Lullymore Heritage and Discovery Park.
  4. Adding to understanding of the role of economic shocks to peatland exploitation (With Dr Aziz Mohibbi).
  5. Understanding machair (with Dr Eileen Tisdall (Stirling University).
  6. Collaborating with Dr Lisa Orme on peatland carbon balance research.

Research Interests

My research explores long-term ecological and landscape change using palaeoecology. I use knowledge from the past to analyse the potential for sustainable and resilient social-ecological futures. I am interested in how a temporal perspective can contribute to conservation in natural landscapes and using knowledge of past ecological dynamics to inform futures.

My research so far has focused on upland environments, both forest and pastoral. My interests span cultural historical landscapes, relict landscapes and rewilding.

I am working with Lullymore heritage and Discovery Park to provide a palaeoecological history of Lullymore bog. The bog is cut over but we can still obtain an early history of ecological change. This work is supported by the Peatlands Community Engagement fund.
