Research Interests

Isolation of Cytotoxic Natural Products from Botanical Sources 

The primary research project in the Still Lab is the use of diverse sources of botanical material, collaborative cytotoxicity screening and NMR-based organic structure analysis to discover bioactive chemistry from plants. The two core areas of this project include cytotoxicity screening and NMR-based organic structure analysis. The biological screening component involves a sulforhodamine B assay performed in the Still Lab at CSUDH and an expanded 19-human tumor cell line panel of Alamar Blue-based assays at local biotechnology company, Molecular Express, Inc., located 5 miles from CSUDH. This research project facilitates discovery of natural products from plants by involving undergraduate student researchers in both the Minority Biomedical Research Support (MBRS) and the Louis Stokes Alliances for Minority Participation (LSAMP) programs on the CSUDH campus.
