Prof. Massimo Zerani is an associate professor of veterinary physiology in the Department of Veterinary Medicine, at the University of Perugia. He graduated with a degree in biological sciences from the Department of Molecular, Cellular, and Animal Biology, at the University of Camerino. His main research interest is the physiology of reproduction in lower and higher vertebrates. In the last few years, he has focused his research interest on the mechanism regulating the lifespan of the corpus luteum. In particular, his research activity concerns the gene, molecular, and cellular mechanisms that regulate the function of the corpus luteum during the different luteal phases, by using in vivo and in vitro experimental models.
