Professor Jeannette Pifer

B.S., Biology, University of St. Francis
M.S., Biology, DePaul University

Jeannette Pifer has been teaching various lab courses and non-major lectures for several years at Lewis University. Prior to Lewis, Ms. Pifer was a Research Associate at Loyola University Medical Center in the Departments of Cell Biology, Neurobiology and Anatomy as well as Microbiology and Immunology. While at Loyola, Professor Pifer's work focused on Cellular Immunology, Cancer Immunology as well as Immunology of aging – research interests she continues today. Like all departmental faculty, Professor Pifer's passion for science leads to her belief that learning should be a hands-on engaging process for all involved.

Professor Pifer teaches the General Biology lab sequence, Anatomy and Physiology lab sequence, and Microbiology lab for majors as well as nursing students, in addition to classes in Pathophysiology, Human Heredity and Human Biology. When she is not engaged in helping students learn, Professor Pifer enjoys an eclectic array of music, traveling and spending time with her family.

Dr. Sarah Powers

B.A., Biological Sciences, University of Chicago
Ph. D., Immunology, University of Chicago

Dr. Sarah Powers joined the Lewis University Biology department in the fall of 2012.  Dr. Powers is interested in development and regulation of cells of the hematopoietic system and how these cells behave normally (in the context of an immune response) and abnormally (in the context of leukemia/lymphoma).  More specifically, her research has focused on the role of cyclin D3 as a cell cycle mediator as well as a component of transcriptional regulation during B lymphopoiesis.

In the classroom, Dr. Powers emphasizes the ability to effectively communicate scientific ideas both orally and in written form.  Dr. Powers teaches Human Heredity, General Biology II, Immunology and various laboratories for both nursing and biology majors.  Outside the classroom, Dr. Powers enjoys baking, photography and dancing.

Dr. James Rago

B.S., Biology, Lewis University
Ph.D., Microbiology and Immunology, University of Minnesota

Dr. James Rago joined the Lewis University faculty in 2006. His professional training lies primarily in the realm of clinical microbiology which led to his current research interests. Dr. Rago studies the prevalence of strains of Staphylococcus aureus in various clinical settings, as well as the antibiograms and genetic properties of selected isolates. Dr. Rago also works in collaboration with faculty from the Chemistry department to assess the antimicrobial activity of silver-coated titanium dioxide nanoparticles.

Dr. Rago teaches courses for both Biology and nursing majors in the department. His course list includes Microbiology, General Biology II, Nursing Microbiology, and Human Heredity, as well as numerous lab courses.
