Oller, Judith

Technician (UdG)

Judith Ollé Vilanova studied Biology, and after graduation, she delved into the comprehensive study of reproductive biology, population genetics, and fish conservation. She began her career as a laboratory technician at IRTA, focusing on the reproductive physiology of target species in aquaculture. Her work involved analyzing molecular markers modulating gamete maturation in seabream and exploring potential hormonal treatments to enhance the reproductive outcomes of species, such as the Senegalese sole.

In 2016, she took on a role as an assistant professor at UdG and concurrently began her doctoral research at the Laboratori d’Ictiologia Genètica. Her doctoral work offered valuable insights into the genetic structure of fish populations. She paid particular attention to the bullet tuna and little tuna, species that hold significant importance in the fisheries sector. By studying their population genetics and phylogenomics, she shed light on essential aspects of these species, advocating for data-driven and sustainable fisheries management practices.

Currently, she is a technician at the Marine Resources and Biodiversity Research Group of the Institute of Aquatic Ecology, where she is researching alternative species to sardines with the aim of reducing overfishing pressures on sardine populations. Her interdisciplinary approach, encompassing reproductive biology, genetics, and conservation ecology, seeks to advance the scientific community's understanding and conservation of aquatic ecosystems.
