My current research focuses on gaining better understanding of dynamics and functioning of biogeochemical processes in terrestrial ecosystems using different modelling tools (including empirical and process-based models). Special emphasis is placed on assessing these processes in relation to soil, climate, as well as land-use (LU)/management practices and their implications for mitigating climate change and environmental pollution. My current and past research spans a variety of areas that include development of risk assessment scenarios for pesticides in soils, modelling of greenhouse gas (GHG) emissions and soil organic carbon (SOC) stocks and carbon stock changes (CSC) in terrestrial ecosystems in relation to LU/management practices and climate, as well as areas of agricultural diffuse pollution, including areas of environmental hydrology and groundwater-/water- quality, and areas of nutrient dynamics (N and C) and their fluxes and pathways in the systems.
Development of risk assessment scenarios for pesticides in soil under PROTECTS project
I am currently working on the development of risk assessment scenarios for pesticide use in Irish agriculture under PROTECTS research project, which will provide baseline information in an Irish context to build towards mitigating the effects of pesticide use on terrestrial ecosystem services, focusing on pollinators and soils. PROTECTS (“Protecting terrestrial ecosystems through sustainable pesticide use”) is a large multidisciplinary research project that involves collaboration of several institutions. The project is funded by the Irish Department of Agriculture, Food and the Marine. Findings from this project aim to help to ensure that pesticides can be used safely while protecting wildlife, health and the environment, both in Ireland and internationally. My research work is performed under Task 4 of the PROTECTS project (task-leaders: Prof Dr Jane Stout and Dr Matthew Saunders, Trinity College Dublin) and it involves, among others, modelling of pesticide risks in soils, and the development of risk assessment scenarios for pesticide use in Ireland. Soils in particular can act as reservoirs for pesticides, and this work should contribute to better understanding of pesticide levels in soils and associated risks. The work further aims to produce a national scale predictive map of likely soil pesticide residue levels and risks as a result of LU/LU-history, climate and soil parameters, as well as to develop recommendations for further development of a national soil monitoring programme.

Modelling of SOC and GHG emissions
I am interested in using biogeochemical and ecosystem models to investigate and predict the effects of LU/management practices on GHG emissions and SOC stocks and changes in different managed and natural terrestrial ecosystems over different temporal and spatial scales. This directly relates to my work performed under two research-projects: - SOLUM project (based in Trinity College Dublin; project-leader: Dr Matthew Sounders) and - AUGER project (based in University College Dublin; project leader: Dr Florence Renou-Wilson). Both are large research projects that involve collaboration of several institutions, and both projects are funded under the Irish EPA Research Programme 2014-2020. My research performed under the SOLUM project focuses on the process-based biogeochemical modelling of SOC stocks and CSC associated with agricultural LU/management practices in Ireland; and my research performed under AUGER project involves predicting GHG emissions in Irish peatlands, with particular emphasis on investigating the anthropogenic impacts on these emissions.
Previously I have been working as a post-doctoral researcher under the CForRep project at the University College Dublin, where my research focused on the measurements and modelling of SOC stocks in Irish afforested mineral soils. I completed my PhD at the Geology Department, Trinity College Dublin (2011). My doctoral research focused on the investigation of the measures (over-winter green cover and tillage practices) to reduce nitrate losses to groundwater from tillage land, with field experiments and majority of laboratory analyses based in Teagasc Research Centres in Ireland.
