Biography
Industrial chemist turned chemical engineer, my career to-date has been earned between industry and academia. My PhD was an industrially based reseach project at the alumina refinery Aughinish Alumina in Askeaton, Co. Limerick. I investigated a unit operation at this site, mimicing the plant reaction in a lab-scale autocalve at in-situ synchrotron facility. I subsequently joined the company for a period as a process engineer. I returned to UL as a post doctorate researcher with the Solid State Pharmaceutical Cluster. This involved managing the day-day activities of a group of post-graduate research student, and conducting research around crystallization and associated phenomena. I became very interested in the pahramceutical industry and moved to the real world of pharma in a transition to MSD (Merck, Sharpe & Dohme) as a project engineer, where I worked mainly on the commercialization of new products.
I have just recently returned to UL as a lecturer for the BEng Chemical & Biochemical Engineering program and look forward to teaching and informing students, while establishing research activities and remaining connected to industry.
