A PhD position is available at Auburn University, with a start date of May 2027 or earlier. The student will join Ian Butts’ Reproductive Physiology Lab in the School of Fisheries, Aquaculture and Aquatic Sciences (SFAAS).
Responsibilities and Tasks
Hybrid catfish production (blue catfish males × channel catfish females) is an important sector of U.S. aquaculture, but producing high-quality sperm from blue catfish remains a major challenge. This project will investigate the physiological and molecular mechanisms underlying gamete quality and reproductive performance, with the goal of improving fertilization and early offspring production.
The student will spend approximately 75% of their time conducting laboratory research and 25% conducting pond-based research. Research opportunities will include:
Predicting and improving sperm quality for in vitro fertilization
Developing gamete quality biomarkers using multi-omics analyses (see Fig.)
Understanding the reproductive physiology of blue catfish
Developing new approaches to improve reproductive performance in hybrid catfish
The student will gain hands-on experience with biochemical, endocrine, molecular biology, cellular, and functional omics techniques, while addressing research questions directly relevant to the aquaculture industry.
