Rhonda C. Vann

Dr. Rhonda C. Vann is a Research Professor in the Department of Animal and Dairy Sciences at Mississippi State University. Her work focuses on animal physiology, stress response mechanisms, and epigenetics in cattle systems.

• Doctor of Philosophy (PhD), Animal Physiology, Mississippi State University
• Master of Science (MS), Animal Science, Texas A&M University
• Bachelor of Science (BS), Animal Science, Texas A&M University

Dr. Vann's research explores how prenatal stressors like transportation affect DNA methylation, immune responses, and behavioral traits in Brahman cattle. Her studies often integrate endocrinology, genetics, and behavioral science to understand stress adaptation in livestock.

Her publications from 2014–2020 highlight interdisciplinary themes in animal physiology, stress-induced epigenetic changes, temperament-genetics interactions, and pharmacological interventions like meloxicam. Key methodologies include hormonal assays, behavioral testing, and genomic analysis.

Dr. Vann has advised graduate students including Laura Brown and Nathan Tissot. She collaborates extensively with researchers like Dr. Randel and Dr. Welsh, contributing to advancements in cattle stress management and reproductive biology.
