Isiah M. Warner, Ph.D.
Vice Chancellor, Office of Strategic Initiatives
Boyd Professor and Philip W. West Professor of Analytical and Environmental Chemistry
Louisiana State University, Baton Rouge, Louisiana

Isiah M. Warner was born in DeQuincy, Louisiana (Calcasieu Parish) on July 20, 1946.  However, he spent his formative years (from the age of two) in Bunkie, Louisiana (Avoyelles Parish) where he attended Carver Elementary and High School.  His interest in science developed at an early age (two years old) when he orally sampled kerosene to determine why this odd smelling liquid was able to produce light.  After a stay in the hospital, he put his science career on hold until the age of twelve when he received his first chemistry set.  Needless to say, he did not resume his oral sampling technique and instead relied on smell and visual observations.  From that point on, there was no getting rid of the science bug.  He took every science course that was offered at Carver High, graduating Valedictorian of his high school class in 1964.

The schools were still segregated in Louisiana and he was offered a full scholarship to Southern University in Baton Rouge, Louisiana (Historically Black College and University).  Between his high school graduation and freshman year in college, he attended a summer institute in chemistry at Southern University.  After this program, the Chair of Chemistry at Southern offered him the opportunity to skip the first year of chemistry if he majored in chemistry, an opportunity which he quickly accepted. He graduated Cum Laude from Southern University with a B.S. Degree in 1968.

After working for Battelle Northwest in Richland, Washington for five years, he attended graduate school in chemistry at the University of Washington, receiving his PhD in chemistry (analytical) in June 1977.  He was assistant professor of chemistry at Texas A&M University from 1977 to 1982.  He was awarded tenure and promotion to associate professor effective September 1982.  However, he elected to join the faculty of Emory University as associate professor and was promoted to full professor in 1986.  Dr. Warner was named to an endowed chair at Emory University in September 1987, and was the Samuel Candler Dobbs Professor of Chemistry until he left in August 1992.  During the 1988/89 academic year, he was on leave to the National Science Foundation (NSF) as Program Officer for Analytical and Surface Chemistry.  In August 1992, Dr. Warner joined Louisiana State University as Philip W. West Professor of Analytical and Environmental Chemistry. He was Chair of the Chemistry Department from July 1994-97, and was appointed Boyd Professor of the LSU System in July 2000. In April 2001, Dr. Warner was appointed the Vice Chancellor for Strategic Initiatives.

The primary research emphasis of Dr. Warner's research group is the development and application of improved methodology (chemical, mathematical, and instrumental) for studies of complex chemical systems.  His research interests include (1) fluorescence spectroscopy, (2) guest/host interactions, (3) studies in organized media, (4) spectroscopic applications of multichannel detectors, (5) chromatography, (6) environmental analyses and (7) mathematical analyses and interpretation of chemical data using chemometrics (chemical data analysis techniques).

Dr. Warner has more than 230 published or in-press articles in refereed journals since 1975.  He has given more than 400 invited talks since 1979.  In September, 1985, he was issued a patent for his work entitled "Process and Apparatus for Chemical Removal of Oxygen in Luminescence Measurements," a patent in September, 1986 entitled "Method and Apparatus for the Stabilization of Direct Current Arc Lamp", and a patent in June, 1998 entitled “Micelle Polymers for Improved Separations of Chiral Species.”  He has since had two additional patents, and has one other patent pending.  He has chaired thirty-one doctoral theses since 1982 and is currently supervising thirteen other Ph.D. theses.

Research

Our research involves fundamental studies in analytical chemistry as well as the development and application of new methods (chemical, instrumental and mathematical), for analytical measurements. The overall goal of these studies is to provide improved methodology for the analyses of complex systems. Although the primary focus is the general area of analytical chemistry, many of our studies emphasize the more specific area of environmental analyses.

Several current ongoing research projects involve varying degrees of chemical, instrumental, and data reduction strategies for the analyses of complex systems. Selected examples of these projects include:

development of chiral separation procedures using novel chiral polymers;
development of novel analytical schemes for environmental measurements;
characterization of human atherosclerotic plaque; and
studies of the influence of guest/host chemistry, e.g., organized media ,on chemical systems of analytical interests.

A number of our projects are funded in the general area of organized media. One type of organized media that we utilize in our separation studies are polymeric surfactants. Polymeric surfactants have many advantages over conventional micelles. They are stable below the CMC (critical micelle concentration), to high concentrations of organic solvents, and stable in the presence of molecules such as cyclodextrins. Cyclodextrins, which exist as the a, b, and g forms, are cyclic oligosaccharides whose torus shaped structure allow size selective binding of hydrophobic molecules. One project has utilized b-cyclodextrin for the chiral separation of 1,1’-binaphthyl-2’2-diamine (BNA) (Figure 1). Another project uses monomeric and polymeric surfactants for the separation of environmentally important compounds such as PAHs (polycyclic aromatic hydrocarbons) and pesticides. We have achieved baseline separation of all 16 PAHs on the EPA priority pollution list.

Another project in our research laboratory involves the characterization of human athero sclerotic plaque. This project is in collaboration with Dr. James W. Robinson. Cardiovascular diseases continue to be major causes of death in the developed world and to some extent, in developing countries, despite the great advances in understanding the factors that contribute to heart disease samples. Previous studies have revealed that, in later years, atherosclerotic plaques are complex lipid deposits, which are large quantities of cholesterol and cholesterol esters. This is illustrated in Figure 2 with data from our laboratory.

A number of other projects are being initiated in the general area of environmental analysis. Briefly, one of these projects will include air pollution monitoring using portable FTIR instrumentation and gas chromatography/mass spectrometry. Other studies will focus on the use of solid phase cyclodextrins to reduce the volatility and oxidation of pollutants, such as polyaromatic hydrocarbons, which are adsorbed on glass filters during air sampling.
