Media development manager bij Vitrolife.
Hubert started his career in the field of ART in 1989 in Brussels. Following a research project on assisted fertilization by subzonal insemination in the mouse, he took part in the development of a clinical program for assisted fertilization that soon resulted in the first pregnancies after ICSI. During the 15 years that he worked in IVF he was an author in >60 peer reviewed articles related to ICSI, embryology, embryo biopsy, PGT, cryopreservation and pregnancy outcome. He joined vitrolife in 2004 where he is now working with medium research. Other areas where his clinical experience is useful are product development, customer support as well as educational and training activities.
