Short CV/Education and training

  • The scientific career of Laia Ribas began with an undergraduate Erasmus scholarship at the University of Wageningen (The Netherlands) with Dr. Hans Komen where she started in the aquaculture field. Next, she did her doctoral thesis at the Autonomous University of Barcelona (UAB) under the supervision of Drs. Simon MacKenzie and Lluís Tort and financed by a predoctoral fellowship awarded by the Catalan Government. In her doctoral thesis, she studied the stress and immune responses in fish in order to find markers for the improvement of aquaculture production. She learned genomic tools, allowing her to secure a postdoc at the Imperial College of London with Dr. Mathew Fisher to study the amphibians’ immune response to fungal infections.

  • On her return, she started working in fish reproduction at the Institute of Marine Sciences (ICM, CSIC) of Barcelona in the group of Dr. Francesc Piferrer. In this group, she has specialized in the study of environmental effects on the gonadal development, describing epigenetic and transcriptomic mechanisms. She also set up an experimental zebrafish (Danio rerio) chamber at the ICM.

  • Since 2017, Laia Ribas is leading her own research to study the interaction between the immune and the reproductive systems in fish, using "-omic" strategies, a field of research barely explored.
