Student projects are available for both biology and chemistry students and can include focusing on one or more of the following areas:

• Isolation, purification, culturing, and identification of marine-derived bacteria. This work is best of biology students, especially those who have taken and enjoyed microbiology.
• Extraction and screenings for biological activity. Typical, this work is done by biochemistry majors interested in learning about biological assays and have plans to take upper level biochemistry courses.
• Purification and structure elucidation of natural products. This is best for chemistry majors who are interested learning about chromatography, mass spectrometery, and structure elucidation. Students interested in this work should plan on taking CHE 445 - Advanced Organic Spectroscopy.

Students can expect to work on interdisciplinary projects, with biology and chemistry majors working in conjunction on the same projects. Though you can expect to specialize in one of the areas described previously, all students will get hands-on practice in all aspects of natural products work. Students can expect to participate in local fieldwork. It is not required, but students who are comfortable in the water and with snorkeling have the opportunity to collect additional microorganisms.

Students who worked in my lab have earned admission to graduate programs to pursue M.S. and Ph.D. degrees in the sciences. Others have successful careers in industry positions.
