Professional practice and commitment to the public sphere

Collaborating Lecturer

I believe that the incorporation of environmental professionals into the public service requires more than technical knowledge; it must include an understanding of the regulatory, institutional, and social frameworks in which decisions are made that impact territory, ecosystems, and citizens, as well as an acceptance of the responsibility inherent to exercising public power legitimized by social trust.

Therefore, preparing environmental scientists for access to senior public administration roles should not be seen merely as technical training but as an opportunity to consolidate judgment, service vocation, and a sense of responsibility.

In this sense, the responsibility of the instructor in designing coherent training content aligned with autonomous, national, and European legal frameworks responds to the need to contribute to a responsible exercise of public power oriented toward the general interest.

Environmental Expert Witness

Contrary to common belief, the issue is not what is evaluated, but under what conditions truth can be asserted when it produces legal and social effects; the expert witness intervenes where the conflict requires a stabilization of meaning, where knowledge is expected to transform uncertainty into a stable point, while knowing that this knowledge can act as premature closure, as a technical pretext or, in certain uses, as a substitute for judicial decision-making when the report ceases to guide the decision and instead functions as a replacement. What is then demanded of truth in that context? Not a conclusive assertion, but a strict relationship with what can be sustained, with its limits and with the inherent consequences of stating it. The problem is not the absence of an answer, but the constant pressure to say more than the framework of knowledge itself allows.

Scientific Research

I maintain several active research lines in the field of biological and environmental sciences such as marine ecology, microbiology, and population dynamics of invasive exotic species.

Biomass dynamics of Caulerpa prolifera under warming, acidification and eutrophication in a mesocosm system.

Cazorla Fernández, V. (in press). Ecologia Mediterranea, 52(1).

Ocean warming, acidification and eutrophication threaten the structure of Mediterranean benthic ecosystems, yet the combined effect of these stressors on opportunistic macroalgae remains insufficiently explored. This experimental study shows that Caulerpa prolifera, a green macroalga widely distributed across the Atlantic and Mediterranean, undergoes exponential biomass growth (from 14 g to 320 g over 12 weeks) under sequential exposure to these stressors in a mesocosm. The research reveals that eutrophication drives the sharpest acceleration in algal expansion, while the species retains tolerance to both extreme temperatures (up to 35 °C) and reduced pH — evidence of its invasive potential under the environmental change projected for the Mediterranean.

Interannual persistence of allochthonous freshwater chelonians in periurban agricultural ponds in Vallès Occidental (NE Iberian Peninsula).

Cazorla, V. (2026). Bulletin of the Spanish Herpetological Association, 37, 197–200.

Invasive North American freshwater chelonians pose a growing threat to Mediterranean wetlands, yet local data on their population persistence remain scarce. This study is the first to confirm the sustained presence of Trachemys scripta (red-eared slider) and Pseudemys concinna in periurban agricultural ponds in Vallès Occidental between 2021 and 2025, reveals their capacity for overland dispersal between nearby water bodies, and provides key evidence for improving the management of invasive fauna in agricultural infrastructure across the Iberian Mediterranean region.

Member of AQUA's Register of Experts

Since March 2026 I have been a member of the Pool of Expert Persons ofAQUA (Agency for University Quality, Andorra) in the field of Environmental Science and Earth Sciences. My role involves external evaluation of higher education programmes, contributing to quality assurance processes and the preparation of evaluation reports.

This activity complements my research and expert witness work, providing an applied and regulatory perspective on the educational quality standards for programmes related to the environment and territory.
