RNDr. Kateřina Komrsková, Ph.D.

Head of Group Reproductive Biology

Kateřina Komrsková is a Head of the Laboratory of Reproductive Biology, Institute of Biotechnology of the Czech Academy of Sciences, and her scientific fosuc targets molecular mechanisms of fertilization and development of new diagnostic tools for quality assessment and gamete selection for Centers of Assisted Reproduction.

Her research interest is focused on sperm-egg interaction and fusion; sperm maturation; epigenetic regulation of early embryogenesis and epigenetic markers associated with human infertility. She recently expands into translational research namely selection of markers and sperm parameters assessment after pathological challenge including cancer.
