Dr. Alexander has many research interests, all related to microbial ecology.  She is a trained microbiologist with specialties in Parasitology, Immunology and Molecular Biology.  She has published peer-reviewed articles focused on bioremediation, EGFR ligands, Chagas’ disease-related pathology, colon cancer, host genetics and disease, gastrointestinal biodiversity and inflammatory diseases in the GI tract.  She currently uses her lab to understand how natural products might prove beneficial in the fight against inflammatory diseases like colon cancer. Her lab’s recent research findings demonstrate a role for species-specific probiotics in reducing colon cancer morbidity and mortality. She is also certified in ethics.  Dr. Alexander, who served as the Deputy Director for Research for Tuskegee University’s Health Disparities Institute for Research and Education, has been actively involved in research that seeks to reduce health disparities in the Alabama Black Belt Counties.
