Dr. Waneene Dorsey serves as the Ernest Everett Just Endowed Professor in the biology department. She earned her Ph.D. in environmental science from Jackson State University. She has published 15 peer-reviewed articles and has nearly two decades of experience in molecular biology research. Her research uses a toxicogenomic approach to identify molecular targets that cause the onset of cancer. This methodology combines toxicology and genomics to understand how molecular events lead to cancer through exposure to chemicals. Ras mutation through signal disruption is seen in roughly half of all colon cancers and 90% of pancreatic carcinomas. Dorsey is studying the Ras/MAPK pathway, a key signal transducing system that facilitates cancer in mammalian cells. She is identifying molecules that turn on cancer gene proteins in mouse liver cells when they are exposed to chlorinated organic compounds. Once the molecular targets have been identified, they can be blocked by various chemicals. These chemicals have the potential to provide a medicinal tool to help prevent the onset of cancer.

Dr. Paul Kim is an assistant professor in the biology department. He earned his Ph.D. in cellular and molecular biology from Colorado State University. He has two years of postdoctoral experience in biomedical engineering and has worked as a research consultant for a biomedical device company. He has published 9 peer-reviewed articles, presented 9 abstracts at national meetings, and holds 4 patents related to biomedicine. His research interest include studying obesity-related diseases, specifically non-alcoholic fatty liver disease (NAFLD). NAFLD is becoming one of the most common liver diseases and, in some cases, NAFLD progresses to the more severe non-alcoholic steatohepatitis, one of the leading causes of liver cirrhosis in the United States. He is working with collaborators and mentors at Colorado State University and the Pennington Biomedical Research Center in Baton Rouge Louisiana. The team is trying to better understand the cellular mechanisms that lead to disease development and progression.

Dr. Frank Ohene is a professor in the chemistry department. He earned a M.S. degree in physical chemistry from Florida State University and a Ph.D. in physical chemistry from the University of Georgia at Athens. His research interests are in multiple areas. They include biotechnology and computational chemistry. His current project in biotechnology involves the preparation and optimization of methodology for the coating of the inner walls of 75 μm ID fused silica capillary tube with non-crosslinked polyacrylamide gel, tailored for the separation of proteins using capillary electrophoresis. He is using Gaussian computational software built in function linear synchronous transit or quadratic synchronous transit approach with the Density Functional Theory and 6-31G basis set. He is investigating the energetics of the interactions between a variety of substituted dienes and different dienophiles in a variety of geometries. Intrinsic reaction coordinate are being performed in order to determine the activation energies of these reactions.
