  3. Research Interests
I am currently (2013) in my fourteenth year of serving on the faculty of Carlow University as Associate Professor of Chemistry in the Division of Natural Sciences and Mathematics. My teaching responsibilities include lectures (and laboratory instruction) in Organic Chemistry, Core Chemistry (Chemistry and Society) and Analytical Chemistry (Quantitative Analysis)/Advanced Experimental Techniques. I also serve as a faculty mentor and course instructor to junior and senior level students enrolled in the “Junior/Senior Seminar” course. I have also created and delivered several special topics courses to increase our department’s offerings to students seeking the chemistry minor. In addition to my academic duties, I serve as the faculty mentor for the American Chemical Society Student Affiliates of Carlow University, and I am currently serving on several standing committees. I have been appointed to a second term as Departmental Chairperson, beginning Fall of 2013.

Fluorescence Derivatization and  Detection Strategies for Capillary  Electrophoresis  Laser‐induced fluorescence has been recognized as the most sensitive method of  detection following separation by capillary electrophoresis. Derivatization chemistry is  often required to extend the advantages of LIF to the target analyte. Fluorophore  design, derivatization chemistry, and detection schemes are investigated and  optimized to permit detection at ultra‐trace levels.  Near‐Infrared Fluorescence  Labeling and Diode‐Laser Induced  Fluorescent Detection  LIF detection schemes in the near‐infrared region of the spectrum are an attractive  alternative to visible fluorescence due to decreased backgrounds and interferences,  and as a result, increased detection sensitivity. The use of high‐powered diode laser  sources can help provide high‐sensitivity at a very low cost. The development of new  fluorophores and derivatization chemistry are critical to the extension of NIR  fluorescence detection to relevant analytes.  Design of Selective Stationary  Phases using Molecular  Imprinting Strategies  Molecular imprinting technology is one method of generating chromatographic  stationary phases which demonstrate a high degree of selectivity for a target analyte.  Imprinted stationary phases have the potential to offer rapid, selective, and rugged  analyses for analytes with clinical, biological, or pharmaceutical relevance.  Bioanalytical  Separation Method Development  Within this broad research category, I am most interested in developing CE and  HPLC separation methodology for analytes with biological, medical, and  pharmaceutical importance. Method development employing multi‐dimensional  separation schemes, selective stationary phases, and highly efficient/sensitive  separation modes can be combined to develop analysis schemes for target analytes at  trace levels in complex matrices.
