Biography and education
Dr. Cesar A. Rosales-Nieto is an Assistant Professor in the Department of Agricultural Sciences at Texas State University. Before joining Texas State University, Dr. Rosales-Nieto worked at the University of San Luis Potosi in Mexico as a full-time Professor, and before that, at the National Institute for Forestry, Agriculture and Livestock Research (INIFAP-Mexico) as a Principal Researcher in Animal Science. Dr. Rosales-Nieto graduated from the Universidad Autonoma de San Luis Potosi (Mexico) with a BSc in Agronomy (Hons). He received a Master’s degree in Animal Reproduction from Texas A&M University-Kingsville. Subsequently, Dr. Rosales-Nieto obtained his Doctoral degree in Physiology of Reproduction from the University of Western Australia. He investigated the role of muscle and fat accumulation on the onset of puberty and the reproductive efficiency of sheep. He was a Fulbright-Garcia Robles scholar and pursued his post-doctoral studies at Michigan State University (USA) on the mechanism that underlies maternal diet manipulation on fetal programming and postnatal development.
