As a Ph.D. in Biotechnology, my work centers on developing sustainable aquaculture feeds through the principles of the circular economy. My research applies biotechnological tools to utilize unconventional ingredients and by-products that enhance the health of farmed fish. This multidisciplinary work is highly applied, involving active collaborations with national and international industry partners. I am deeply committed to reducing animal experimentation. To achieve this, I employ advanced in vitro digestive modeling techniques for aquaculture species, a methodology I implemented through my work with the University of Almería. Beyond research, I am passionate about knowledge transfer and education. I am currently an Assistant Professor of Zoology at the University of Almería (Almería, Spain). I have supervised student internships, served on evaluation committees for academic theses, and actively engaged in science outreach, including the European Researchers’ Night. Throughout my academic trajectory, I have participated in multiple research projects, published scientific papers, and presented my findings at various conferences. Moving forward, I aim to apply my expertise in enzyme biochemistry and in vitro modeling to address emerging challenges in fish nutrition, physiology, and sustainable aquaculture.
