Patrick O’Leary is a native of Cork, Ireland and has been working in the School of Chemistry as a lecturer since September 2004.   

His Previous studies include a Bachelors of Science (B.Sc, 1995) degree and a Ph.D from University College Cork.  His Ph.D Research concentrated on the Rhodium (II) Catalysed Buchner reactionOn completion of his Ph.D he was awarded the inaugural Post Doctoral Fellowship in The Sciences from the National University of Ireland in 1999.  This Fellowship is awarded after an open competition among scientists throughout Ireland and only one is awarded  every two years.  This fellowship allowed Patrick to study the use of the Buchner reaction as the key step in a challenging natural product synthesis.

On completion of the NUI-postdoctoral fellowship Patrick moved to Utrecht to work in the Department of Metal Mediated Synthesis with Prof. Gerard van Koten and Dr. Bert Klein Gebbink.  During the following two years he worked on immobilisation and recycling techniques for chiral homogeneous catalysts. This was achieved via the non-covalent immobilisation of homogeneous transition metal to silica materials.

During his time in Utrecht Patrick also acted as expert editor of a  published report on the activity in the area of chemistry of the COST funding body over the years 1999-2001.
