Dr David Kelleghan is an occasional lecturer and researcher within the School of Biosystems and Food Engineering in University College Dublin. He is an Irish section committee member of the Chartered Institute for Ecology and Environmental Management, and his PhD was ranked in the top 10 projects for research impact in UCD in 2019. His work focuses on monitoring and modelling environmental impacts of atmospheric ammonia from agriculture. As a Fulbright TechImpact Scholar, Dr Kelleghan will visit Iowa State University to further develop ammonia sensors used there. The primary goal of his scholarship will be to enhance low cost ammonia sensors suitable for deployment in both Ireland and Europe. Improving both the ease of use, and accessibility to such low-cost sensors will enhance the level of monitoring conducted across Europe. This will subsequently improve both the accuracy of atmospheric dispersion modelling and environmental assessments.
