Dr. Lisa Lyford
Assistant Professor of Biology

L. Lyford

Dr. Lisa K. Lyford is a graduate of the University of Massachusetts at Amherst, earning a B.S. in Biochemistry with minors in Chemistry and Music Performance. After advanced study in Microbiology and Immunology and employment in a cellular immunology lab, she turned her attention to pharmacology. Her research focused on the electrophysiological properties of a nicotinic acetylcholine receptor in the brain. She earned her doctorate in Pharmacology from the University of North Carolina at Chapel Hill in 1999, and continued her research on the structure and function of nicotinic receptors as a postdoctoral associate. She has also taught courses in Mutagenesis and Biotechnology in the Biotechnology Education Facility at North Carolina State University as a postdoctoral teaching associate. Dr. Lyford joined the biology faculty at the University of the Cumberlands in August, 2005.

Dr. Lyford is a member of the Association for Biology Laboratory Education, the American Association for the Advancement of Science, the American Society for Microbiology, and the Kentucky/Tennessee Branch of ASM.
