I am a faculty member in the Thomas H. Gosnell School of Life Sciences. I received a B.S. in Biology from Virginia Union University in 2000 and a Ph.D. in Plant Biology and Pathology from Rutgers University in 2006.

Job Responsibilities

My responsibilies centers around teaching and research.
1. Cell and Molecular Biology
2. Fundamentals of Plant Biochemistry and Pathology
3. Molecular Ecology
4. Biospearations: Principles and Practices

Research Interests

The research in my laboratory focuses on amino acid metabolism. Specifically, I am interested in  aminotransferase class of enzymes. These enzymes are involved involved in the metabolism of amino acids in living organisms. The overarching theme of my research program is to elucidate the function(s) of uncharacerized enzymes involved in amino acid metabolism. In addition, I am interested in strutural biology as it relates to the three-dimensional structure of enzymes that are involved in amino acid metabolism.
