Susan Klein

Susan Klein 
Chemistry Chair
Biology-Chemistry Program Director

Dr. Klein came to Manchester in the fall of 1998. She has an undergraduate degree from Franklin and Marshall College with a minor in Ancient Greek Civilization. Her Ph.D. is from the University of Wisconsin where she studied the rates of organic reactions. Her primary responsibility at Manchester is teaching Organic Chemistry. Additionally, she teaches Intro to Organic and Chemical Science. She also currently holds the position of Chair of the Biology-Chemistry Council, Chair of the Chemistry Department, and advisor to the American Chemical Society Student Affiliates.

Jeff Osborne

Jeff Osborne
Associate Professor of Chemistry

Dr. Osborne has been at Manchester since 2004. He received his undergraduate degree from Goshen College and his Ph.D. from the University of Illinois at Urbana-Champaign. His graduate work involved structure and function of integral membrane proteins. He did postdoctoral work at the University of Minnesota, studying biodegradation of pollutants. At Manchester, his primary teaching responsibility is biochemistry and general chemistry.  His research projects involve enzymes that degrade environmental pollutants. He also directs the Medical Practicum trip to Nicaragua over January Session.  Visit Dr. Osborne's web page.

Rachel Polando

Rachel Polando, Ph.D.

University of Notre Dame, 2009. Graduate research area: The role of pattern recognition receptors in host cell signaling and phagosome maturation during infection with Leishmania. Courses taught: Human Biology, General Biology, and Introduction to Molecular Biology, Microbiology, Cell Biology, Parasitology, and Medical Microbiology. Current research interests include: cell signaling during phagocytosis and phagosome maturation, effects of serum components on cell signaling and phagocytosis, cytokine effects and regulation during phagocytosis, and host-parasite interactions.

Gregory W. Clark

Gregory W. Clark 
Associate Professor of Physics
Coordinator of the Engineering Science Program

Dr. Clark has been teaching at Manchester since the fall of 1992.  He graduated from Indiana University at South Bend with majoring in physics with minors in French and mathematics.  He earned his M.S. and Ph.D.  degrees from Indiana University with a minor in inorganic chemistry.  His current research focusses on atomic force microscopy and quantitative electric force phase microscopy of nanomaterials.  He teaches the calculus-based physics sequence and several upper-level courses for majors including electricity and magnetism, analytical mechanics, materials physics, and electronics.  He also teaches introductory courses in energy issues and physical geology as well as a travel course, The Making of the Modern Mind.

Kathryn L.Davis

Kathryn L. Davis, Ph.D., arrived at Manchester in the fall of 2010. She obtained a B.S. in Chemistry and a B.A. in German from Hope College in 2005. She then completed her Ph.D. at the University of Pittsburgh in 2010, where she studied charge transfer in biomolecules. Her areas of interest are physical chemistry and analytical chemistry, with her primary teaching responsibilities in physical chemistry and general chemistry. Her research interests are in the photoluminescent and electrochemical properties of carbon nanodots made from soy milk. Dr. Davis is also a member of the Manchester Symphony Orchestra.
