Samuel Santos-Ribeiro M.D., Ph.D.

Biografía

Samuel Santos-Ribeiro obtained his medical degree in 2007 from Nova Medical School (Lisbon), concluding his training in Obstetrics/Gynaecology at Hospital Santa Maria (Lisbon) in 2015.

In 2013, he also initiated a 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.

He is currently the Scientific Coordinator and Senior Gynecologist at IVIRMA Lisbon. The primary focus of his ongoing research is the relationship between infertility treatments and endometrial receptivity.
