Reproductive Biology
Pouya Dini, DVM, PhD, PhD, Dipl. ECAR, Dipl. ACT
Assistant Professor in Equine Reproduction
Department of Population Health and Reproduction (PHR)
(see also: Translational Research, Microbiology)
Research Interests: My research topics include parental gene expression in the placenta and the reciprocal paternal and maternal gene interaction in the equine's placental development and its pathologies, effects of assisted reproductive techniques on the epigenetic of the equine placenta, and host-pathogen interaction during equine placentitis. We use high-throughput sequencing along with classical molecular and cellular biology techniques to explore these topics.
Possible learning outcomes:
1- Culture cells and organoid from reproductive tract (mainly equine)
2- Extract nucleotides and PCR
3- Get familiar with next-generation Sequencing methods
4- Get familiar with in vitro embryo production in equine and bovine

Ghislaine Dujovne, DVM, MS
Assistant Professor in Clinical Theriogenology
VMTH
Dr. Dujovne is a theriogenologist whose clinical work focuses mainly in equine reproduction. Dr. Dujovne's research interests focus on reproductive problems of clinical relevance on mares and stallions. Dr Dujovne’s main interest is efficient clinical management of reproductive diseases and artificial reproductive techniques. She has participated in research related with estrus suppression in performance mares, endometritis treatment in mares, stallion semen quality, post-mortem sperm recovery in stallions and semen evaluation in canine semen.
Potential for a STAR student to participate in a clinical trial to determine safety of intrauterine treatment in mares to treat endometritis. Skills you will learn are: basic horse handling, palpation and ultrasound skills. Sample obtention and organization.

Dr. Gagneux is interested in primate molecular diversity. His lab investigates the evolutionary mechanisms responsible for the generation and maintenance of primate diversity, its potential roles in protecting populations from pathogens as well as potential consequences for reproductive compatibility. He is currently studying cell-surface molecules of sperm cells in closely related primate species. His focus is on glycans, the oligosaccharides attached to glycolipids and glycoproteins of the cell surface. The numerous parallels between the surface molecules of successful pathogens and those found on the surface of mammalian sperm, invite the analogy between internal fertilization and “extremely successful infection”. These interests examine the differences in sperm surface molecules and sexual selection (via sperm competition and cryptic female choice) and whether such differences might contribute to reproductive incompatibility and speciation due to female immune rejection of sperm with incompatible glycoconjugates. Dr. Gagneux has studied the behavioral ecology of wild chimpanzees in the Taï Forest, Ivory Coast, population genetics of West African chimpanzees, and differences in sialic acid biology between humans and great apes with special consideration of their differing pathogen regimes. His great concern is that the current surge in interest for comparative genomics is not being translated into direct support for the conservation of primates in their endangered natural habitats.

The overarching goal of my research program is to promote the sustainability of dairy farming and help safeguard the food supply for humankind.
For 2027, there will be projects occurring on the impact of NGF on the hypothalamic-pituitary-ovarian axis, Validation of New Methods For Judicious Use of Antimicrobials in Dairy Cows, Impact of Rumen Protected Choline on Health, Lactation, Reproduction and Fetal Programming.
