Our Scientific Team

Waterstone Clinic has built the most advanced laboratory of its kind in Ireland, and our facilities are matched by our incredible team of scientists. Our scientific team have medical, research and technical backgrounds, with most holding PhD degrees.

Our team of embryologists and andrologists are led by Dr Tim Dineen and Dr Xiao Zhang.

Our embryologists are responsible for assisting with all laboratory based fertility procedures; monitoring and incubating embryos; assessing and freezing eggs, sperm and embryos; performing biopsies on embryos; and maintaining clinical records. Our senior embryologists are certified in their speciality by the European Society of Human Reproduction and Embryology (ESHRE), which is an internationally recognised laboratory qualification. 

Our andrologists specialise in male health and fertility. They are responsible for semen analysis; semen cryopreservations; sperm preparations for IUI and IVF/ICSI; and maintaining clinical records. 

Our embryologists and andrologists work as a team and you will meet them during your treatment.
