Geetha has a Bachelor degree in Zoology from the University of Jaffna (Sri Lanka) and Masters degree in Biotechnology from University of Greenwich (United Kingdom).

She is now in her third semester of her Masters in Fisheries Biology and Management at UiB. She’s rearing hundreds of guppies at different oxygen levels to study the effect of oxygen on their growth and maturation schedules. Her project is collaboration between EvoFish and Fisheries Ecology and Aquaculture groups, supervised by Beatriz Diaz Pauli and Mikko Heino from EvoFish and Jeppe Kolding from FEA.
