My students explore the coordination chemistry of sulfur containing ligands (such as thioethers or thioureas) to cobalt(III). These projects are a blend of a variety of chemistry disciplines. Students often prepare the organic molecule we want to attach to cobalt, the appropriate cobalt precursor, purify the resulting complexes, and then characterize them by UV-visible and NMR spectroscopies.
My primary teaching interests are introductory chemistry courses such as CH 105 (Chemical Principles), CH 111 (General Chemistry I), and CH 112 (General Chemistry II). I truly enjoy helping students obtain a solid chemistry background. In addition, I currently teach laboratory sections of CH 321 & 322 (Organic Chemistry) and lecture and laboratory for CH 440 (Forensic Chemistry).
