MA in Biomedicine

Greta Ann Herin has taught a wide variety of courses in general biology, biomedicine, and general education. Courses include: Advanced Human Anatomy; Faith, Science and Ethics; Human Anatomy and Physiology I and II; Neuropsychology; Advanced Neurobiology (undergraduate and masters-level students) ; Mammalian Physiology; Molecules, Genes, and Cells; Biological Explorations; and a Senior Seminar “The Elephant and the Rider”. She has also co-taught Concepts in Biology; a Senior Seminar “Form, Finitude and Faith”; a Senior Seminar “Origins”; and a Colloquium “Passion and Obsession”.

Greta Ann serves as a Pre-professional Health Sciences advisor.

She has dual Bachelors Degrees in Biochemistry and Psychology from Kansas State University and a Ph.D. in Neurobiology from the University of Pittsburgh School of Medicine. Her dissertation covers interactions among modulators of NMDA receptors, an important glutamate receptor in the brain. In addition Dr. Herin did a post-doctoral fellowship at the Max-Planck Institute for Brain Research in Frankfurt, Germany. There she studied metabotropic glutamate receptors.
