Professional Interests

Dr. LaCourse’s research interests include basic and applied research on hydrodynamic electroanalytical techniques in liquid chromatography and capillary electrophoresis, adsorption phenomena at noble metal electrodes, and advanced sample preparation techniques (e.g., microdialysis and pressurized-fluid extraction). A major thrust of his efforts is to further understand and expand the limits of pulsed electrochemical detection (PED) techniques for the determination of polar aliphatic compounds. Dr. LaCourse applies PED to (bio)analytical problems of critical significance in the areas of pharmaceutical, toxicological, forensic, environmental, pharmaceutical, and life science arenas.

Research Description

In the Faraday Cage
The LaCourse Group – 2005

Research in the LaCourse group involves the development of tools and methodology for the determination of polar aliphatic compounds (e.g., carbohydrates, amines, and sulfur-containing moieties with weak chromophores) in a variety of matrices. Hence, our research interests include basic and applied research on hydrodynamic electroanalytical techniques, adsorption phenomena at noble metal electrodes,practically all chromatographic techniques including capillary electrophoresis,  and advanced sample preparation techniques (e.g., microdialysis and pressurized-fluid extraction). The LaCourse group is known world wide for its research on Pulsed Electrochemical Detection.
