Fellow
Durham, North Carolina, USA
David J. Kroll, PhD, is a biomedical educator and natural products cancer pharmacologist focusing on the discovery of novel compounds from diverse natural sources, including botanical dietary supplements. He is currently Professor and Chair of the Department of Pharmaceutical Sciences at North Carolina Central University. He is also guest faculty and graduate advisory board member for the MS program in Science and Medical Journalism at The University of North Carolina at Chapel Hill.
Dr Kroll holds a BS in Toxicology and a PhD in Pharmacology & Therapeutics. He launched his independent academic research program, supported by the National Institutes of Health and the American Cancer Society, by studying the mechanisms of chemotherapeutic drug resistance. As more than half of anticancer drugs are derived from plants, microbes, or marine organisms, Dr Kroll has always held high regard for nature as a source of chemical diversity in the discovery of drugs for a variety of therapeutic areas and worked at one point with the co-discoverers of Taxol (paclitaxel). In 1995, historical curiosity and his role as a pharmacology professor led him to develop educational modules on the truth and fiction behind herbal remedies and non-botanical supplements. Public demand for such objective information has occasioned Dr Kroll becoming widely sought by print and broadcast media as a reliable source on the quality of supplements and for identifying misinformation about them.
Dr Kroll is currently funded by the NIH National Cancer Institute for research to identify and characterize anticancer and chemopreventive pure compounds from milk thistle (Silybum marianum). He also serves on the NCI’s Office of Cancer Complementary and Alternative Medicine Physician’s Data Query Editorial Board.
