Ken Kassenbrock, MD,PhD has been an avid hunter of wild mushrooms since the late 1970s. Trained as a physician-scientist, he has worked in Cell and Molecular Biology, including post-doctoral work with the brewer’s yeast, Saccharomyces cerevisiae. Although his interests in fungi were initially largely culinary, over the years they mushroomed (what else?) to include other aspects of the biology of this fascinating kingdom including ecology, toxicology, biotechnology and cultivation. Avocation and vocation eventually converged, and Ken currently teaches Mycology (mushrooms, molds, mildews and more) at Colorado State University, where he is on the faculty in the Biology Department.
