Background

Dr. Denis O Shea holds a BSc (Hons) Chemistry from the National University of Ireland, Maynooth and having completed a study into the design and synthesis of novel chemotherapeutic compounds [within the Inorganic Pharmaceutical and Biomimetic Research Group under the supervision of Dr. Michael Devereux] was awarded his PhD from Dublin Institute of Technology. He joined the School of Food Science and Environmental Health as a lecturer in Chemistry and Pharmaceutical analysis in 2000.

Research Interests

  • The synthesis and characterisation of novel transition metal based complexes and investigation of their antimicrobial, anti-cancer and catalytic/biomimetic activity.

  • Design of quantitative techniques for the measurement of metal ion absorption by fungal species.

  • Design of quantitative techniques to determine ergosterol production of C. albicans

  • Investigation of photodeacctivation of sunscreens.

Publications
