Diploma in Applied Science (Dublin Institute of Technology), BSc(Applied Sciences) (University of Dublin), PhD (University of Utah).

Profile:

Lecturer in Analytical Chemistry in DIT, Kevin Street.

Appointed Assistant Head of School in 2001.

Awarded Professorship of DIT 2009

Academic Interests:

Research interests include Analytical Chemistry and Instrumentation. This involves the theory and operation associated with Modern Analytical Instruments in the area of spectroscopy, electrochemistry and chromatography.

Current research interests:

  • Thin electroactive films as sensing layers, use of covalently attached porphyrins in films for electrochemical catalysis and mediation, especially for analysis in flowing streams.
  • Reflectance spectroelectrochemistry using both infrared and ultraviolet wavelengths for the study of processes at electrode surfaces.
  • Simulation of diffusion processes, potential and current distributions and comparison with experimental results.
  • Examination of interactions between gases and conducting polymer layers with a view to developing gas sensors.
  • Electrochemical destruction of trace organic molecules in wastewaters and recovery of precious metals.
