Dr. Meaney graduated in 1998 with a Diploma in Biomedical Sciences from the Dublin Institute of Technology and a B.Sc. from Trinity College Dublin. After a brief period in the pathology laboratory of Waterford Regional Hospital he accepted a post-graduate research position at the Karolinska Institute in Stockholm. His post-graduate research was on cholesterol oxidation products called oxysterols, under the mentorship of Prof. Ingemar Bjorkhem. In 2003 he was awarded his PhD and continued as a post-doctoral researcher at the Karolinska Institute, investigating the role of oxysterols in the brain.
In December of 2004 he became the first Irish person to be awarded a Swedish Brain Foundation post-doctoral research fellowship which provided substantial momentum for continuing his research and enabled him to initiate a significant project on the development of a novel transgenic model, which was subsequently funded by Pfizer. It also enabled him to investigate the regulation of pathways for brain cholesterol elimination.
In late 2006 he returned to Ireland where he began working as a Research Project Grants Officer at the Health Research Board, Ireland. In 2007 he returned to the School of Biological Sciences to take up a position as a Lecturer in Biomedical Biochemistry, with responsibility for both undergraduate and postgraduate teaching and research. He is now assistant head of the School of Biological Sciences.
