Research

I am interested in guiding students at the undergraduate and graduate level in the process of scientific research. This includes learning technical skills of organic synthesis, use of state-of-art instrumentation for characterization of molecules and quantitation of chemical and environmental impurities. I am also interested in developing career skills for the students whom I mentor. These include networking, volunteering, creative and artistic thinking, and refining oral and written communication skills. To achieve engage these interests, I develop projects that match students interest and needs for professional development. The projects range from organic synthesis to environmental chemistry and they cover basic and applied research and collaborations with local industry.

Projects in my research group:

- Synthesis and spectroscopic characterization of organic compounds containing Naproxen as a chiral auxiliary;

- Quantitative measurement of heavy metal environmental impurities including Fe, Pb and Ag;

- Applications of the Polyol Induced Extraction or PIE process for separation of water from organic solvents for purposes of recycling the solvents and isolation of natural products.

Teaching

                  I teach the following courses:

Introduction to Organic and Biological Chemistry (Chem 1113/1114). This is a lecture laboratory course that is specifically tailored for students pursuing degrees in the allied health sciences such as nursing and community health. I am also developing an on-line version of this lecture and laboratory course.

Organic Chemistry Laboratory (Chem 3532). This laboratory course supports the lecture course in organic chemistry by providing hands-on application of the concepts that are taught in the lecture with the aim in enhancing students understanding of concepts in organic chemistry and developing their laboratory skills.

  Spectroscopic Characterization (Chem 6743/6744). This is a graduate level lecture and laboratory course where students are assigned a set of unknown compounds. They learn how to drive state-of-art instruments in the department (FT-IR, GC-MS, LC-MS, NMR, FT-IR and UV-Vis) improve their understanding of spectroscopy to solve the structures of the unknowns.
