Dominika Krol

Research Officer

Research Interests

I am a research officer in the area of agricultural gaseous emissions. I also hold an adjunct lecturer position in the College of Science and Egineering at NUI Galway. My research interest include impact of nitrogen management on nitrogen fluxes in grazed grassland systems, especially quantification and mitigation of nitrous oxide and ammonia in agricultural systems. I am interested in sustainable manure management and contributing to refinement of national emission inventories.

I am a member of Manure Management Network and a co-editor of the 2020 ammonia MACC ‘An Analysis of the Cost of the Abatement of Ammonia Emissions in Irish Agriculture to 2030’.

My research team currently consists of 2 post-doctoral researchers and a technician, 4 PhD students and one MSc student, I am also co-supervising 5 PhD students. I regularly give lectures in agricultural gaseous emissions to third level students in NUIG, UCD and WIT and get involved in public outreach and stakeholder engagement activities.
