Research

GIS

A lot of my current research is based around GIS mapping using QGIS

Remote Sensing

I'm using multispectral and synthetic aperture radar remote sensing data

Python

I use the Python language for programming and data analysis

LimerickAir

LimerickAir is a project to build a network of low-cost air pollution monitors across Limerick. Results are published daily on Twitter @limerickair

Flooding

Flooding is a serious problem in Ireland, and is getting worse due to climate breakdown. We need accurate flood risk maps, and natural flood defenses.

Early animal evolution

The oldest animal fossils appear shortly after the global Snowball Earth glaciations. Is this a real evolutionary signal, or an artefact of how the earliest fossils are preserved?

Teaching

Currently lecturing at Mary Immaculate College and the University of Limerick
Natural Hazards

Natural Hazards

University of Limerick

This module will examine the nature, extent, frequency, risk, and potential for mitigation against a range of natural hazards, including volcanic eruptions, earthquakes, tsunamis, flooding, wildfires, extreme weather, landslides, pandemics, the climate crisis, and extraterrestrial hazards. Drawing heavily on case studies, including media coverage and the academic literature, students will explore these hazards from both physical and human geographic perspectives.

Geographic Research Methods and Mapping

Geographic Research Methods and Mapping

University of Limerick and Mary Immaculate College

This module will investigate three key areas of the formal research process, namely, data acquisition, data analysis and data representation. Techniques and methods with application in both human geography and physical geography will be covered, including GIS mapping.

Evolution of the Irish and British Landscape

Evolution of the Irish and British Landscape

University of Limerick

This module examines the evolution of the landscapes of Ireland and Britain, firstly in a geological context, and secondly by focussing on the role of geomorphological processes that have modified and shaped the landscape. The first part of the module will examine the major mountain building episodes and associated tectonic processes that have punctuated the geological history of the Irish and British landscapes, providing the foundations of initial landscapes. The second part of the module will proceed to investigate the earth surface processes that have sculpted and shaped these landscapes to produce the characteristic landforms that we observe today.

Field Studies in Geography

Field Studies in Geography

Mary Immaculate College

This module aims to provide intensive training in a wide range of geographical techniques through the format of a residential field course. The module will focus on interpreting both the human and physical landscapes, and will cover some of the fundamental aspects associated with field work such as field observations and accurate recording in a field notebook; qualitative and quantitative data collection techniques (e.g. archives, census data, interviews, survey questionnaires, photography, transects, surveying) and data analysis, interpretation and presentation.

Resolution of the earliest metazoan record: differential taphonomy of Ediacaran and Paleozoic fossil molds and casts

Resolution of the earliest metazoan record: differential taphonomy of Ediacaran and Paleozoic fossil molds and casts

MacGabhann, B.A., Schiffbauer, J.D., Hagadorn, J.W., Van Roy, P., Morrison, L., Lynch, E., and Murray, J. 2019. Palaeogeography, Palaeoclimatology, Palaeoecology 513, 146-165.

Analysis of their preservational mode suggests that the first metazoans, which would have lacked high molecular weight biopolymeric tissues, could not have been fossilized as molds and casts in coarse clastic sediments. Understanding the origin and earliest evolution of the Metazoa requires a focus on alternative modes of fossilization.

The Cryogenian Period

The Cryogenian Period

Shields-Zhou, G.A., Hill, A.C. and MacGabhann, B.A. 2012. In: Gradstein, F.M., Ogg, J.G., Schmitz, M.D., and Ogg, G. (eds) The Geologic Time Scale 2012, pp. 393-412. Elsevier, Boston.

The Cryogenian Period is characterized by evidence for at least two prolonged episodes of widespread, even global, glaciation and the contemporaneous reappearance of sedimentary iron formations.

Ediacaria booleyi – weeded from the Garden of Ediacara?

Ediacaria booleyi – weeded from the Garden of Ediacara?

MacGabhann, B.A., Murray, J., and Nicholas, C. 2007. In: Vickers-Rich, P. and Komarower, P. (eds) The Rise and Fall of the Ediacaran Biota. Geological Society of London, Special Publications 286, 277-295.

Sole markings from the Upper Cambrian Booley Bay Formation at Booley Bay, Co. Wexford, Ireland, previously described as the Ediacaran-type fossil Ediacaria booleyi appear to possess a number of morphological characteristics which are not consistent with assignment to the genus Ediacaria, nor any other known Ediacaran taxon.
