RESEARCH My research is divided into 2 themes: Igneous petrology: my core research is focussed on using novel petrological/geochemical techniques to understand the architecture/dynamics of magma systems. I have developed a multidisciplinary research method which integrates these datasets with aspects of petrography, geophysics, thermodynamics, fluid mechanics and analytical development. Environmental geochemistry: since arriving in TCD, I have established the Earth Surface Research Laboratory as a national geochemical facility. I have directed the lab through a 2-year process to obtain a prestigious ISO17025 accreditation and manage a €2.5M GSI grant to maintain the facility and run Government analyses. In founding the ESRL, I developed a new interest in environmental chemistry, specifically investigating heavy metal pollution in urban soils. I have established a vibrant research group which currently includes 2 technicians, 1 postdoc, 1 PhD and 1 research MSc student, with another 2 PhDs and 2 postdocs arriving in the next 6-24 months (and 1 MSc pending approval). I supervise one of the technicians as a part-time PhD student and co-supervise a PhD student in the UK. I also have 2 long-term Visiting Academic Fellows intending to join the group in the next 6 months. Since arriving in TCD, I have published 6 papers in top journals as first/co-author (2 in Nature Communications), with 2 in review and 1 for imminent submission. I have funded this research through competitive grants and postgraduate studentships, including: an SFI Frontiers for the Future Project (€625,552 FEC), an IRC Postdoctoral Fellowship (€91,970 FEC) and a Provost's PhD Award (€131,240 FEC). I am also co-I on NERC Future Leaders Fellowship and GSI Short Call project, and recently contributed to a successful GSI Equipment Call. TEACHING I have a research-led teaching philosophy, using my experience in volcanology/environmental geochemistry to show students how theoretical chemistry/physics can be applied to solve real-world problems. By introducing them to recent research breakthroughs and outstanding challenges, I aim to produce inquisitive, independent students with the ability to pursue their own interests. I have developed a Senior Freshman module (Introduction to Geochemistry) which equips SNS students with the chemical background required to undertake advanced geochemistry courses. This is a theory-heavy course, requiring innovative teaching to engage students: I contextualise conceptual ideas with clear geological examples in lecturers and run practicals where the students apply their learning to real-world datasets. I also embed quizzes within lectures to retain attention. I am currently taking over the Geology Research Methods module and am working with colleagues to explore novel teaching methods. I am also developing a Senior Sophister module in Advanced Igneous Petrology, which will provide TCD students with the skills required to pursue volcanological research, building on Ireland's reputation as a centre of excellence in this area. To continue improving as a teacher, I am undertaking an MEd in Higher Education in the School of Education. COLLEGE CONTRIBUTION I am the Geology International Students Coordinator and SNS Global Relations Committee rep. The department has recently seen an increase in the number of students wishing to take a year abroad, and I have been working to facilitate greater mobility through streamlining the Geology Erasmus programme (better integration with the TR062 course) and exploring opportunities for new Erasmus agreements. I am a College Tutor and enjoy supporting students, even with some of my Chamber struggling through difficult circumstances during COVID. I have extensively represented the College nationally and internationally: I regularly engage with the media (print, radio, TV), I am a member of a UK Government committee on national geoscience resourcing, and I've made high-level policy contributions

My research has previously focused on using novel geochemical and petrological techniques to understand the structure and processes operating within sub-volcanic magma systems. However, since arriving in Trinity, I have diversified my work into magmatic mineralisation (specifically critical raw materials) and environmental geochemistry; these themes use my existing skills but tackle a broader range of societal problems, allowing me to target a greater diversity of funding oportunities. VOLCANOLOGY My volcanological work uses empirical analyses of erupted rocks and minerals alongside thermodynamic models to decipher the architecture and dynamics of Earth"s sub-volcanic crust. In many cases, my research aims to understand controls on the timing and style of volcanic eruptions, using this information to better inform the interpretation of monitoring data at Earth"s surface. However, I also pursue more fundamental problems, aiming to understand links between Earth"s mantle, crust, and surface volcanism. My work in this area uses study sites in Italy, the Canary Islands and Galapagos. MAGMATIC MINRALISATION My economic geology research seeks to understand how magmatic processes drive the accumulation of metals to form extractable mineral deposits. Again, this multidisciplinary work integrates state-of-the-art geochemical analyses with thermodynamic and fluid dynamic modelling. I am principally interested in mineralisation of critical raw materials (e.g. Platinum Group Elements), which are essential in modern/green technologies but have a high risk to supply. My work is focused on using Irish igneous centres as a "natural laboratory" to understand mineralising processes, and aims to unlock Ireland"s potential as a supplier of novel raw materials as well as improving global exploration efficiency. ENVIRONMENTAL GEOCHEMISTRY Through directing the ESRL, I have recently begun collaborating on several project in Environmental Geochemistry. These include understanding how land use patterns correlate with heavy metal pollutants in Dublin soils, and how trace nutrients impact crop performance using novel growth media.
