Dr. Ahmed Yousif Abdalla Mohamed

Research Fellow, Civil Struct & Env. Eng.

Dr. Ahmed is a Research Fellow in the Department of Civil, Structural and Environmental Engineering at Trinity College Dublin. He holds a Ph.D. in Civil Engineering from University of Galway, and MSc in Sanitary Engineering from IHE-Delft, The Netherlands.

Dr. Ahmed is passionate to work in water and wastewater projects and to participate in the research and development of this field especially within the area of resources recovery. His research interests include wastewater treatment and modelling, nutrient recovery, aerobic granular sludge (AGS), constructed wetlands, sand filtration, chemical coagulation, microalgal-bacterial synergy, GHGs emissions. and environmental microbiology.

Currently, he is working on a project related to elucidating life cycle of microbial aggregates in aerobic granular sludge (AGS) system. The study will investigate a series of microbial size aggregates to differentiate between growing and nongrowing important microbial communities belonging to functional groups responsible for nitrogen and phosphorus removal. This will be achieved using a genome-resolved meta-transcriptomics approach to identify active and non-active populations across a series of microbial size aggregates present in the AGS system. The outcome of this study will enhance our understanding of the life cycle of granular biofilms of the AGS system, which will help improve the granular stability and function of AGS system.

He is also working on another project called WASTEMISSION funded by Environmental Protection Agency (EPA), Ireland. The overall aim of the WASTEMISSION project is to improve estimates of Ireland’s greenhouse gas (GHG) and air pollution emissions associated with wastewater treatment from both centralised and decentralised systems.

So far, he has published in Water Research, Science of the Total Environment, Journal of Cleaner Production, Journal of Environmental Management. He has also served as a reviewer for Water Research and Science of the Total Environment Journals.
