Areas of Expertise: Neuroendocrinology, cell ultrastructure, reproductive biology

Background Information:

I obtained the Ph.D. degree in Anatomy (with focus on microanatomy) at the University of Kentucky and had a few years of postdoctoral training at the same institution and at the University of Missouri. Prior to joining UIS, I taught medical and graduate courses in anatomical disciplines (neuroanatomy, histology/ultrastructure, gross anatomy) at the University of Arizona and at the University of Louisville, and did neuroendocrine research at the same institutions for some fifteen years. My focus at UIS is on teaching and research instruction, at undergraduate and graduate (Master’s) level in the areas of interest described below.

Teaching Interests:

My teaching interests cover subject areas from a structural (gross or microanatomic) or functional (physiologic) prospective. Over the years, I have taught at UIS the subjects listed below. Asterisks identify the subjects I have taught in the most recent years. The course level is indicated in parentheses. The undergraduate courses are at 300 level, graduate courses are at 500 level, while 400 level courses are open to both undergraduate and graduate students.

Research Interests and Student Research Instruction

My past research focused on neuroendocrine control of reproduction in mammals, using both an ultrastructural and a physiologic approach. More recently, my interests shifted from a warm-blooded vertebrate (rat/hamster) reproductive study model to a less well-understood, cold-blooded vertebrate (frog) model. Two of our undergraduate students completed research projects involving the role of the fertility factors derived from the frog oviduct on the motility of the frog spermatozoa, and presented their work at the UIS Science Research Symposium. For the graduate and undergraduate students interested in research, many questions remain unanswered regarding the control of the amphibian reproduction.

I am also interested in using the transmission and scanning electron microscopy as a tool to study invertebrate and protozoan function. In collaboration with the department’s faculty, I have explored the endosymbiotic relationships between the cyanobacteria and the gut epithelial cells in an aquatic crustacean (Daphnia). More recently, I became interested in studying the ultrastructural correlates of bacterial function. These fields are also open to student research projects.
