ANATOMY AND CELL BIOLOGY College of Medicine GRADUATE FACULTY 1989-90 Chairman: M. H. Ross. Graduate Coordinator: K. E. Rarey. Professors: M. A. Clendenin; C. M. Feldherr; E. Kallenbach; L. H. Larkin; L. J. Romrell; M. H. Ross; R. A. Wallace. Research Scientist: G. S. Bennett. Associate Professors:T. G. Hollinger; P. J. Linser; K. E. Rarey; K. E. Selman; C. M. West. Assistant Professor: W. A. Dunn, Jr. The Department of Anatomy and Cell Biology offers a program leading to the Doctor of Philosophy degree in the medical sciences. There are currently two graduate training programs within the Department: a) cell and de- velopmental biology, and b) general anatomy. The general anatomy concentration emphasizes the full range of traditional anatomy offerings while cell and developmental biology concentrates on the subject mat- ter of those fields and molecular biology and gives the student the option to deemphasize other areas of train- ing. Research interests in the Department include several different areas of cell biology, developmental biology, reproductive biology, and vertebrate morphology. Applicants should have a strong background in biol- ogy, chemistry, or physics and have taken undergraduate courses in organic chemistry, calculus, physics, cell bi- ology and biochemistry. Deficiencies may be made up during the first year of graduate study. The Department does not accept students into a program of study leading to the degree of Master of Science.
