Dr. Michael Williams

Assistant Professor (Botany)
BOTANY SCHOOL

Assistant Professor (Trinity Centre for the Environment)

Dr. Michael Williams joined the College in 1992 as a joint lecturer in the Botany Department and the Environmental Science Unit (now the Trinity College Centre for Environment). He is a member of the Plant Physiology research group. His primary research activity centers on the measurement and modeling of below ground soil processes in agricultural systems. Other research interests include photosynthesis and respiration in higher plants and algae. Ongoing Projects Measurement and modeling of soil respiration in arable and pasture soils. Funding Agency - EPA and EU Measurement and modeling of nitrous oxide emissions in agricultural soils Funding Agency - EPA Soil mineralization and pasture management in a Mayo catchment. Funding Agency - Teagasc Previous Projects Physiological studies of salt tolerance in Plantago maritima. Funding Agency - Enterprise Ireland Respiration and carbohydrate metabolism in higher plants.
