“I enjoy teaching and discovery in the life sciences, especially through the hands and minds of students. My highly rewarding career at Coker extends from the opportunity to engage students both inside and outside the classroom, sharing my experiences and abilities to foster the next generation of future scientists, teachers, and scholars.”
My passion centers on understanding the fundamental characteristics of life and applying tools to expand our knowledge of biological processes. I enjoy teaching introductory biology courses, beginning and advanced courses in molecular biology, genetics, and biochemistry.
In addition to my teaching and service responsibilities, I engage students who participate in research projects both in summertime and during the academic year. Typically, 8-10 students participate in my laboratory during the semester. Students may be supported by grant funds or receive academic credit for taking on a research project. Recent graduates who have performed a research project in my lab that have continued to pursue advanced degrees (or gained permanent employment) include:
- Sara Atkinson (’14) – MUSC, Occupational Therapy Program
- Megan Sexton (’13) – North Carolina State University, PhD program in Plant Pathology
- Rebecca Armentrout (’12) – McLeod Medical Hospital, Medical Technology Program
- Mandi J. Warner (’11) – Southern Illinois University, PhD program Plant, Soil and Agricultural Systems
- Bryan Musungu (‘11) – Southern Illinois University, PhD program Plant, Soil and Agricultural Systems
- Elizabeth Stamey (’10) – Biology teacher, Chesterfield High School, SC
- Kayla M. Gerberich (’10) – Senior Biological Scientist at the University of Florida, awarded MS in Plant Pathology from Purdue University
- Andrew J. Shychuk (’10) – awarded MD from the University of South Carolina School of Medicine
- Shelly M. Catlett (’09) – awarded DDS from The Medical University of South Carolina, College of Dental Medicine
- A. Michele Burnham (’09) – awarded MS in Plant Pathology from University of Georgia, currently USDA research scientist, Exotic and Emerging Avian Disease Research Unit, Athens, GA.
- Ashley D. Zearfoss (’08) – awarded MS in Plant Pathology from North Carolina State University, awarded PhD program in Biochemistry at Clemson University
- Amber B. Rayfield (’08) – University of Arkansas, awarded MS in Animal Science/Genetics
- Jessica L. Winburn (’07) – The Ohio State University, awarded MS in Plant Biotechnology
Independent laboratory research is an essential educational component for students aspiring to become future scientists, medical doctors and science teachers. The research program that I have developed at Coker University focuses on gene discovery in filamentous fungi, with particular emphasis on elucidation of regulatory networks controlling development in foliar plant pathogens. The research conducted at Coker University is synergistic with both Drs. Jin-Rong Xu’s and Larry Dunkle’s respective programs at Purdue University and Dr. Burton Bluhm’s program at the University of Arkansas, providing opportunities for undergraduate students at Coker University to participate in University-level research projects.
Genomic approaches and field studies are being used in my program to understand fungal biology. We employ real-time qPCR and microarray analysis of gene expression to characterize developmental mutants of Fusarium graminearum. Field studies are focused on understanding the effects of crop selection on Fusarium populations. Student-driven projects are facilitated by collaborations with scientists from government (USDA-ARS), industry (Monsanto), and academia (Purdue University).
Together with Coker University’s institutional commitment to providing resources to stimulate research experiences for undergraduates, my research program has benefitted from extramural support from the SC-EPSCoR Collaborative Research Program (CRP), IDeA Network of Biomedical Research Excellence (INBRE), the South Carolina Independent Colleges and Universities (SCICU), and the National Science Foundation (NSF-CAREER award no. 0845324). Student-driven projects are facilitated by collaborations with scientists from government (USDA-ARS), industry (Monsanto), and academia (Purdue University and University of Arkansas).
