Dr. Cruzen teaches various courses in the Biology Department including: Cell and Molecular Biology, Biochemistry and Microbiology.  Dr. Cruzen’s research interests are focused on the process of aging in the nematode worm Caenorhabditis elegans. He and his students are looking at morphological development of different long lived and wild type worms. They analyze the surface characteristics of the pharynx and the vulva in developing and aging worms by scanning electron microscopy to identify chronological and developmental changes (worm wrinkles) in the two groups of worms. The basic question has to do with when wrinkles are acquired with respect to their physiological and chronological age.
