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.

Contracts, technological or transfer merits.

Continued participation in knowledge-transfer activities linked to the aquaculture and fisheries sector, including collaboration with the National Chamber of Aquaculture (Ecuador) and technical contributions to projects aimed at optimising Pteria sterna culture, improving productive performance and sanitary management in mariculture systems. Significant contribution to the EU FP7 project PARASITE, focused on parasite risk assessment in European fish production chains, with direct transfer to regulatory bodies and marine health agencies. Active dissemination through sectoral forums (AQUAEXPO, Ecuadorian Aquaculture Congress, FIRMA), communicating scientific results to industry professionals, cooperatives and environmental authorities. Additional experience in science communication and public engagement through participation in the design and development of the Museo Megaterio (UPSE), supporting educational innovation, public understanding of science and the 
social valorisation of natural heritage.

I am Dr. Eva Sanjuán, an Assistant Professor (Ayudante Doctor) affiliated with the Department of Microbiology at the University of Valencia (UV) and an member of the PAFZP (Pathogens in Aquaculture: Fish and Zoonotic Pathogens) research group since its establishment. After completing my Bachelor’s degree, I was hired as a Research Assistant in Dr. Amaro’s laboratory and began my doctoral thesis titled “Epidemiology and Phylogeny of the Pathogen V. vulnificus Biotype 2.” My PhD was awarded Excellent Cum Laude and honored with the “Extraordinary Doctoral Award.”

After earning my doctorate, I was invited to join Dr. Seshu’s laboratory at the University of Texas at San Antonio (UTSA). During my postdoctoral research, I focused on investigating the global regulatory protein Carbon Storage Regulator A (CsrA) and its role in the biology of Borrelia burgdorferi.

In mid-2010, I rejoined the laboratory of my former supervisor, Dr. Carmen Amaro, to participate in the MICROGEN project. I developed a research project that was awarded a highly competitive “Juan de la Cierva” fellowship in 2011. Over the course of this three-year project, I sequenced the genome of a Vibrio vulnificus biotype 2 strain and developed a custom microarray to study the mechanisms of infection in both fish and human hosts.

Since the conclusion of my Juan de la Cierva (JdC) fellowship, I held several postdoctoral research positions funded by various national projects. During this period, I primarily served as a research supervisor in the laboratory, mentoring and guiding multiple doctoral students while contributing to the experimental design of a significant portion of the studies conducted during that time. In February 2023, I secured my first position as an Assistant Professor at the University of La Laguna (ULL) in Tenerife.

As a principal investigator, I have led a project funded by the ULL-Campus of International Excellence and actively contributed to 18 national and international research initiatives, including a project under the European Sixth Framework Programme, a CONSOLIDER project. During all these years I have also participated in numerous collaborative agreements with industry and institutional partners. My research output, as documented in the SCOPUS and Google Scholar databases, includes 29 and 37 publications, 761 and 1,136 citations, and an H-index of 16 and 19, respectively. I currently supervise one doctoral candidate and have guided 6 Master’s projects and 12 undergraduate theses to completion. Additionally, I have mentored 15 vocational training students in laboratory techniques at both higher and intermediate levels. I have been recognized with two ‘sexenios de investigación’. I am an appointed external expert on Vibrio for the ECDC and the EFSA. Notably, I was invited by EFSA to participate as an expert in the working group on public health risks associated with the consumption of Vibrio-contaminated foods.
