Alex Goikoetxea - has now defended and finished his thesis, congratulations Alex!

Alex's full name is Alexander Goikoetxea Pérez de Mendiola, and originally from Vitoria-Gasteiz, in the Basque Country, Spain. He completed his BSc in Biotechnology at the Universitat de Barcelona and carried out his BSc Dissertation in the North West Cancer Research Fund Institute at Bangor University, Wales, in the field of Cancer Genetics.

He then did an InterUniversity MSc in Aquaculture as 3 joint modules, each from a distinct university: Universitat de Barcelona, Universitat Autònoma de Barcelona and Universitat Politècnica de Catalunya, completing his MSc thesis at L'Aquàrium de Barcelona, which involved research on the diet of Mediterranean fish living in shallow algal communities.

As a PhD student in the Gemmell lab, Alex's research will contribute to the elucidation of the molecular basis behind sex change reversal in mainly protogynous species of fish.
