Ph.D., University of Louisville
Analytical & Environmental Chemistry
Dr. Voegel is an analytical chemist and teaches introductory, general, analytical, bioanalytical, and environmental chemistry courses. Undergraduate research projects in his laboratory focus on analytical and environmental chemistry.
Analytical research focuses on phthalocyanine and related compounds, which have diverse uses in rewritable compact discs, dyes, aerobic catalysis, electrochemical sensors, and many other areas. Students synthesize metal pyridinoporphyrazines and characterize the products using UV-visible spectroscopy, FT-IR, and mass spectrometry. The catalysts are used the aerobic oxidation of thiols to disulfides, which are verified using GC/MS, and to prepare chemically modified electrodes for detection of theophylline and cystiene and other thiols.
In the environmental area, water quality in Lakes Maurepas and Pontchartrain have been examined to observe the potential effects of freshwater diversions from the Mississippi River and included work relating to the 2008 opening of the Bonnet Carré Spillway. Water quality parameters measured include conductivity, temperature, chlorophyll a, nitrogen, phosphorus, and pH. Student’s participating in this work gain both laboratory and field sampling experience.
