Areas of Expertise
I am an Analytical Chemist interested in all types of application, especially environment. My research is focused on the use of flow based analytical tools such as flow injection analysis, sequential injection analysis, and reverse methods. I am also interested in development of new colorimetric chemistries for environmental analysis and general approaches to improving spectroscopic detection.
A second, and growing, area of interest of mine is that of chemical informatics. This is the intersection of Chemistry with Computer Science and Information Management. I am developing scientific digital archives, an electronic laboratory notebook called Eureka, and a markup language to capture experiment data called ExptML.
Doctor of Philosophy in Analytical Chemistry, September 1994
Department of Chemistry, University of Massachusetts, Amherst, MA
Bachelor of Science (Honors) in Chemistry and Analytical Science, July 1988
Department of Chemistry, Loughborough University, Loughborough, Leics UK
I attended Loughborough University in the UK for my B.Sc. Hons. (D.I.S.) in Chemistry and Analytical Science. During the third year of my degree I completed an industrial internship at Kodak Ltd, in Harrow, Middlesex and earned the Diploma in Industrial Studies (D.I.S.) part of my degree. In my final year at Loughborough I worked for Dr. Julian Tyson as a research student.
For graduate school I following Dr. Tyson across the pond to the the University of Massachusetts at Amherst. There I studied novel ways to doing chemical reactions for analysis in the technique of Flow Injection Analysis (FIA). I also started getting interested in computers and informatics at this time and generated a searchable database of references in the area of FIA.
After five years at UMass (and the publication of four research papers) I graduated and moved on to Duquesne University in Pittsburgh. Under the direction of Dr. Skip Kingston I worked on open vessel microwave digestion methods for environmental analysis.
After two years of postdoc I applied for faculty positions around the U.S. and took my current position at UNF. I joined UNF in 1996 as an Assistant Professor in the then Department of Natural Sciences. My initial research on FIA led to UNF's first two patents awarded in 2001. Also, in 2001 I was part of a successful NSF proposal to build the Analytical Science Digital Library. In 2002 I was part of a consortium of faculty that was funded by the U.S. Department of Defense to build sensors for chemical warfare agents (this was post 9/11 of course). Recently, I have been working on environmental analysis of cyanide, phosphate, and arsenate from two different perspectives - reagent optimization and remote monitoring. In addition, my research ideas have moved into the area of chemical informatics - the use of information systems to enhance research in Chemistry.
