Summary: I obtained my PhD in Marine Sciences (University of Alicante, 2014) and have since built an interdisciplinary profile in zoology that integrates, marine parasitology, biological oceanography and advanced statistical analysis. My research combines morphological, molecular, and quantitative approaches to characterise the diversity, transmission pathways and ecological relevance of parasites, pathogens and epibionts in mesozooplankton communities, and to understand how these symbiotic interactions respond to oceanographic variability in coastal and upwelling systems. During my predoctoral stage (JAE-CSIC competitive
fellowship), I co-designed and implemented the zooplankton sampling strategy of the CAIBEX oceanographic campaign, focused on the African upwelling system. I applied combined plankton sampling techniques, advanced taxonomic identification, and molecular analyses. I identified several scientifically relevant hosts–parasite associations (e.g., Bolbosoma balaenae, Rhadinorhynchus spp., Anisakis pegreffii, Ellobiopsis sp.) and described a new epibiont species, Pelagacineta hebensis. These contributions involved morphometrics, dissection, DNA extraction, PCR (COI, 18S), primer design and phylogenetic reconstruction (BLAST, ClustalW, MEGA). Additionally, I have broad experience in ecological and statistical modelling, including PCA, PCO, PERMANOVA, DistLM, dbRDA, and ANOVA I/II with full assumption testing. My scientific output comprises 16 publications, 70% in top-25%
CiteScore journals, one book chapter, 21 conference contributions, and an h-index of 8 (267 citations). I have participated in nationally and internationally funded projects such as FP7-PARASITE, CAIBEX, and LARECO, and served as Principal Investigator of the JOYA project on the biology of Pteria sterna and pearl production. I have held scientific responsibility in MEDITS campaigns, coordinating the systematic collection of biological samples.
My career also includes national and international mobility in leading research institutions, strengthening my research independence, my integration into multidisciplinary teams, and the consolidation of long-term collaborations in Europe and Latin America. Throughout my trajectory, I have combined research in marine parasitology, plankton ecology, aquaculture, and vertebrate palaeontology. These thematic shifts, linked to opportunities in different institutions, retain a strong zoological coherence based on the comparative study of morphology, ecology, and organism–environment interactions. Palaeontology strengthened my morpho-functional analytical skills, while aquaculture allowed me to apply zoological principles to living organisms and real challenges in sustainability and food security. This versatility has enriched my methodological and conceptual approach to contemporary marine parasitology.
Contribution to society. My research has direct relevance for aquaculture, coastal environmental management, and marine sustainability. I have collaborated with public institutions and the productive sector in Ecuador to improve farming practices, assess sanitary risks, and support responsible aquaculture development. I maintain an active commitment to outreach through symposia, Expociencia, seminars, and public engagement activities. Training and mentorship. I have accumulated around 2,000 hours of university teaching in invertebrate and vertebrate zoology, malacology, and aquatic animal pathology. I have supervised four BSc
and two MSc theses, served on five thesis committees, and supported early-career researchers in statistical analysis, laboratory methods, and scientific writing. At the University of Valencia, I coordinate the interdisciplinary Biograu project (230 students/year), promoting scientific communication, critical thinking, and inquiry-based learning. I also develop innovative teaching resources, gamified activities, and accessible digital materials.
Other contributions. I am a reviewer for Aquaculture Environment Interactions and a member of the Equality Commission of the Faculty of Biological Sciences, contributing to institutional initiatives on inclusion and gender perspective. My background includes experience in zoological collections, marine fauna necropsies, and comparative morphology. Overall, my career reflects emerging leadership, research autonomy, technical excellence, and a sustained commitment to open science, training, and the transfer of knowledge to society.
