Tematyka badań:

I am a PhD student in the Embryo Biology Team, where I investigate the mechanisms of ovarian tissue activation in prepubertal heifers. My research falls within the field of reproductive biology and aims to understand the molecular and biological processes that regulate follicular development in prepubertal heifers. This interest stems from a desire to improve the efficiency of livestock breeding and to explore the fundamental mechanisms of reproductive development.

My scientific interests revolve around reproductive biology, with a particular focus on the molecular mechanisms regulating the female reproductive system. I am currently undertaking my first advanced research project in this area, which opens up new perspectives on understanding the early stages of sexual maturation in cattle.

The main objective of my doctoral work is to identify and characterize the molecular signaling pathways involved in the initiation of ovarian tissue activation. In the course of my research, I work both with in vitro culture systems and live animals. The findings of this study may contribute to the development of new strategies to support fertility in livestock production, as well as enhance our overall understanding of mammalian reproductive physiology.
