Diana Pazmiño

Marine Biologist

Diana is a marine biologist born and raised in the Galápagos islands, passionate about conservation and education. She obtained her undergraduate degree of Biology in Pontificia Universidad Católica del Ecuador in Quito (PUCE) and moved to Australia for her PhD. These experiences broaden her professional and personal perspectives about women in STEM and inspired her to encourage women participation in science. After coming back to Galápagos in 2017, she joined the Universidad San Francisco de Quito (USFQ) and the Galápagos Science Center (GSC) to develop several research and community engagement projects. Diana is aware of the disconnection between the local population and researchers, and the negative impacts over long term conservation goals. She is convinced joining efforts at regional and global scale is key to move forward and achieve permanent solutions. 

Her projects include long term monitoring of rays (and manta rays) in the Galápagos islands, as well as the use of molecular tools to inform conservation and tackle illegal activities. Diana is currently building a genetic database for the diversity of the Galápagos through barcoding and metabarcoding techniques, while supporting local capacity building and community participation.

Diana will be joining the July 12 departure of the Ecuador & the Galápagos program.
