Research Fellow

Karine joined the Pépin lab in 2025 and quickly became involved in projects covering ovarian biology, AMH, and a small zoological tour of reproductive science: cats, mice, dogs, humans, and now rhesus macaques. A veterinarian by training, she enjoys working across species to tackle questions in reproductive biology and endocrinology.

She holds a Master’s degree in Animal Science from UFRGS (Brazil), where she specialized in in vitro fertilization, and earned her PhD in Molecular Medicine from Université Laval (Canada) in 2024 under the supervision of Dr. Jacques J. Tremblay. Her doctoral research focused on the molecular mechanisms of MEF2 transcription factors in testicular Leydig cells, adding a molecular and endocrine perspective to her long-standing interest in reproductive biology.

Project:Evaluation of the effect of exogenous AMH on ovarian function and fertility in rhesus macaques.
