Biography

Currently working as a Senior Researcher (Environmental Research Scientist and Modeller) with a DAFM-funded project " Ensemble Modelling: Inter-comparison of process-based models for prediction of C and N emissions from Irish agriculture and their uncertainties" - integral part of an inter-institutional project "Irish Land UsES" collaborated by Teagasc (Coordinator), UCD (SBES, EI and Forestry), DIT and AFBI, NI. The overall project objective is to investigate policy or management scenarios in developing low carbon strategies, to provide a multi-disciplinary decision support system for policy makers by adapting to existing models, and develop a range of policy scenarios. 
Also associated with ERA-GAS FACCE-funded international project "Managing and Reporting of Greenhouse Gas Emissions and Carbon Sequestration in Different Landscape Mosaics (GHG-Manage)" and the collaborating countries are France, Germany, Ireland, Poland and The Netherlands. The main objective is to assess GHG exchange characteristics of typical European landscape types, both on mineral and organic soils, including CO2, CH4 and N2O emissions, using existing and new experimental data, and make these accessible for quantification tools such as the Cool Farm Tool (CFT) and process-oriented whole farm models.
Immediately before, worked as a senior researcher attached to UCD with EPA and DAFM-funded projects such as: (1) Sourcing and Assessing Agricultural Activity Data for Modelling and National Estimates of Greenhouse Gases and Air Pollutants, and (2) Development of methodologies and simulation of process-based models for accounting and reporting greenhouse gases (GHGs) emitting from Irish agriculture and associated land use change.
Before that worked as a Research Officer (Project Coordinator/Manager) at Teagasc Environment Research Centre, Wexford, Ireland with a DAFM-funded project on "Subsoils and Groundwater Denitrification". During the mentioned project periods, involved as a partner/collaborator in some Teagasc and UCD-led research projects on emission and mitigation of GHGs from Irish agriculture and also co-supervised the research works of post-graduate/PhD  and European work placement students. 
Following MS and PhD in Environmental Soil Chemistry under a twining programme between Ghent University Belgium and Universiti Putra Malaysia,  did post-doctoral research for >4 yrs in UK, Germany and Japan with prestigious fellowships awarded by the The Royal Society, Alexander von Humboldt Foundation and Japan Society for the Promotion of Science, respectively. Also a former Senior Scientific Officer of Bangladesh Institute of Nuclear Agriculture, Mymensingh with research focused on soil-water-nutrient interactions in agricultural soils.
Published more than 150 scientific papers in peer-reviewed journals/proceedings/popular/book chapters, supervised scientific staff and post-graduate students, offered specials classes to under- and post-graduate students, reviewer of several international journals, evaluated PhD proposals, secured research funding from national and international funding bodies, etc. 
Main research interests are: 
  1. Biogeochemistry of carbon and nitrogen cycles in terrestrial and aquatic systems using conventional and isotope techniques. 
  2. Soils and Climate Change: measurement, monitoring and mitigation of GHGs and air pollutants emitting from agricultural systems. 
  3. Development of methodologies for accounting and reporting emission of GHGs and SOC density/stocks in agriculture and the associated land use change using together with high resolution databases and GIS approaches.
  4. Development of empirical/mechanistic models and improvement of process-based models for estimation/simulation of GHGs, SOC density/stock and their changes, as well as air pollutants.

Research

Research Interests

On-going research activities

Project (Inter-institutional; DAFM-funded):
Ensemble Modelling: Inter-comparison of of process-based models for prediction of C and N emissions from Irish agriculture and their uncertainties.
Objectives:
  • To investigate policy or management scenarios for the reduction of GHG emissions o an enhancement of forestry/land use removal to assist policy makers in developing low carbon strategies.
  •  To create cross model comparability to provide a multi-disciplinary decision support system for policy makers by adapting to existing models.
  • To develop a range of policy scenarios following consultation with policy end users from the DAFM, such as intensification of livestock production or forest expansion. 


Project (International; ERA-GAS FACCE-funded):
Managing and Reporting of Greenhouse Gas Emissions and Carbon Sequestration in Different Landscape Mosaics (GHG-Manage)
Objectives: 
 
  • To assess GHG exchange characteristics of typical European landscape types accessible for quantification tools e.g. the Cool Farm Tool (CFT, http://www.coolfarmtool.org/ ) and their use on organic soils and for CH4 & N2O emissions.
  • To investigate if there are optimal configurations of landscape elements and management practices that lead to internal compensation of GHG emissions, whilst considering their economic impact.
  • To quantify the effects of important compensating mechanisms on regional to national scale GHG emissions and soil carbon stocks.
  • To design methodologies to report and verify the effects of landscape scale GHG emission compensation mechanisms.
