Research interests: Ecophysiology and comparative reproductive neuroendocrinology; with an emphasis on the biochemistry of steroid hormones and their mechanisms of action on the reproductive organs and the central nervous system. As well as studying with an ecophysiological approach to the animal stress process. Mainly my studies are focused on wild, endemic, and endangered vertebrate species. As well as studying the fundamental processes of the biology of animal development.
