He obtained his medical degree from Nova Medical School (Lisbon), concluding his training in Obstetrics/Gynaecology at Hospital Santa Maria (Lisbon). He performed the Clinical Scholars Research Training (Harvard Medical School) and a research programme at Universitair Ziekenhuis Brussel (Brussels) with his Ph.D. thesis focusing primarily on the optimisation of endometrial receptivity during ART. He is currently the Clinical Director and Scientific Coordinator at IVIRMA Lisbon and an Invited Professor at the Faculty of Medicine of the University of Lisbon. The primary focus of his ongoing research is on the optimization of endometrial receptivity and ART safety.
