Eduardo Gastal, Professor

Animal Science

Dr. Gastal’s interests are focused on fundamental and applied studies in animal reproduction. In his studies, he uses the mare and cow as primary animal models and small ruminants. His research program's goals focus on advancing knowledge of mechanisms for improving reproductive efficiency, inducing contraception, and overcoming health-reproductive issues caused by obesity and aging in these animal species.

Jones B. Graceli, Assistant Professor

Animal Science

Dr. Graceli has a PhD in reproductive and metabolic endocrinology from the Johns Hopkins University School of Medicine.

The main focus of the Dr. Graceli study is to determine the environmental factors and nutritional factors that affect the metabolic and reproductive system. Specifically, the research in his laboratory is designed to address the following major questions: (1) Which genes and hormones regulate the normal development and function of the adipose tissue and ovary? (2) What are the effects of environmental toxicants on the development and function of the HPG axis? (3) What are the mechanisms that underlie the effects of reproductive toxicants on the HPG axis? (4) Are environmental exposures associated with metabolic and reproductive abnormalities in animal models?
