Research Interests:

Research Training


2003 – 2000   Ph.D. Dissertation, LSUHSC-S, Shreveport, LA. Laboratory of Kelly Tatchell. Subject: The regulation of glycogen metabolism and ion transport by protein phosphatase type 1 in Saccharomyces cerevisiae.

2000 – 1996   M.S. Thesis, LSUHSC-S, Shreveport, LA. Laboratory of Kelly Tatchell. Subject: A novel role for the regulation of yeast ion homeostasis by GLC7.

1996 – 94       Student research worker, Center for Excellence in Cancer Research, Treatment and Education, Department of Hematology/Oncology, LSUHSC-S, Shreveport, LA. Supervisors: Rhonda Berroteran Ph.D., J. Abra Watkins Ph.D., and Jonathan Glass, M.D. Subject: Screen human genes for complementation of yeast genes for iron uptake.

1996 – 94       Masters candidate and graduate assistant, Department of Biological Sciences, Louisiana Tech University, Ruston, LA. Research Mentor: James Liberators, Ph.D., Subject: Analysis of proteins liberated from cercariae of Schistosoma mansoni

1993 – 92       Research Fellow, Environmental Protection Agency (EPA), Spelman College. Supervisor and Sponsor: Victor Ibeanusi Ph.D., Subject: Bioremediation: I assisted my EPA research fellow sponsor with experiments for removal of lead and aromatic hydrocarbons from mixed microbial systems such as water and soil using molecular biological techniques. This experience included a 1993 summer scientific associate experience at the Environmental Protection Agency Research Facility in Athens, GA under the supervision of Rochelle Araujo, Ph.D.

1991              Summer Intern, Department of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, Supervisor: Jerry Johnson, M.D., Subject: I developed a dermatopathology computer-based module teaching module for medical students. All participants presented their projects. 

I have training and expertise in molecular genetics using Saccharomyces cerevisiae (budding yeast) as a model organism. I joined the LSUS faculty in the fall of 2003 immediately after the completion of my dissertation work. In that time, I have served as the principal investigator or co-investigator for university-, state-, National Science Foundation (NSF)- and National Institutes of Health (NIH)-funded grants. I have trained several undergraduate and graduate students in my research laboratory (e.g., Young Noh, Brandy Ervin, Krystl George, Randolph Stone, Trey King, Phoebe Rollyson, Amber Williams, Dominique Washington, Samantha Johnson Murphy, Adna Curukovic, Gary Wrobel, Neal Traweek, Christopher Madere, and Elizabeth Cockerham) – most of whom have matriculated into professional schools or a scientific career. I have served as a faculty and research mentor for a diverse population of future science professionals. Furthermore, I serve as the Faculty Advisor for three undergraduate student organizations (Alpha Epsilon Delta Honor Society, Minority Association of Pre-health Students and the PreDental Society) and I have also served as the Director of the Master of Science in Biological Sciences program in the Department of Biological Sciences. Each semester I have nine to twelve contact hours per week with students teaching lecture and laboratory courses: Principles of Genetics, Medical Genetics, General Biology, Biological Inquiry, Applied Biotechnology, Scientific Communication, Visual Experiments, Health Sciences Capstone, and Independent Study/Research. 



Selected Publications:

My first two publications illustrated a new role for protein phosphatase type 1 (Glc7) in budding yeast: ion homeostasis. These early studies reveal findings produced during my dissertation research in collaboration with fellow students under the guidance of Dr. Kelly Tatchell. The “power of yeast genetics” has allowed us to reveal novel cellular pathways for Glc7 that might correlate with mammalian PP1 regulation of cell division, glycogen metabolism, and ion transport.

Upon joining the LSUS faculty I engaged in collaborative activities with colleagues. We optimized methods for teaching statistical analysis to students in general biology laboratory courses. The first author initiated the teaching methods described in this work with suggestions for various troubleshooting solutions from co-authors.

Alpha-synuclein (a-syn) and lipids are the two main components of Lewy bodies found in affected neurons of patients with Parkinson’s disease. This publication reveals 40 genes that, in high copy, suppress the toxicity of human WT-a-syn in budding yeast. My contribution to this work was the genetic screen of human genes in wild-type and mutant yeast strains.

FC101 is a mycotoxin produced by Fusarium equiseti that causes plant diseases such as wilt, scab, and rot. Several studies revealed that FC101 inhibits the growth of 35 human cancer cell lines, increases apoptosis of melanoma cell lines and reduces tumor growth in mice. These studies reflect our current findings using human cancer cell lines and Saccharomyces cerevisiae (budding yeast) to identify the molecular target(s) of FC101.
