Our team is composed by a group of highly-skilled professionals and collaborators who hold extensive knowledge of every aspect of the diagnostic and environmental management. The extended experience of our human team in the assessment of surface water bodies in most of the river basins on the Iberian Peninsula, makes us a trustworthy unit in this kind of studies.

Pepita Nolla i Querol. General Manager.

BSc Biology, my professional career has developed in the limnology field and ecology quality of rivers, reservoirs and lakes. Specialized in benthic diatoms, cyanobacteria and freshwater phytoplankton, I have been involved in several evaluation projects of ecological status of rivers, lakes and reservoirs in DMA implementation. I am also proficient in the use of biological indexes based on diatoms and phytoplankton.[ResearchGate]

Xavier Benito Granell. Analyst.
BSc Biology and Environmental Sciences, PhD Climate Change. I’m specialized in the study of aquatic organisms (diatoms and foraminifera) to assess the ecological status of continental and transitional water bodies (lakes, coastal lagoons, estuaries, rivers). My professional career has centered around environmental change, management and education of aquatic ecosystems; being myself open to new challenges at work. I actively participate to international organizations in the field of environmental sciences by fostering scientific dissemination as a tool to societal transformation.

Soraya Hernández Llamas. Analyst.

BS Biology. Phytoplankton and diatom analyst. I started my career on microscopic analyses with the OstreoRisk project (ICM-CSIC) about microalgae blooms of Ostreopsis associated with massive die offs of marine fauna and punctuated periods of toxicity for humans. Currently, I’m specialized in the ecological assessment of rivers, lakes and reservoirs using different biological indicators (benthic diatoms, phytoplankton and cyanobacteria). With constant awareness and curiosity to learn about the natural world that surrounds us.

 Mª Carmen Trapote. Analista.

BSc Environmental Sciences and Industrial Engineering. PhD Paleoecology. I’m specialized in evaluating environmental change and impacts through the analyses of biological indicators, including diatoms and pollen. All things related to nature fascinate me, and that’s why I keep myself in constant training and learning.


 Enric Aparicio

PhD Biology. Specialized in Ichtyology and river’s ecology, lakes and reservoirs, he has run multiple projects related to the assessment of ecological status quality, study and conservation of continental ichtyofauna, environmental flows, fluvial connectivity, fishing plan management and restauration projects and improvement of fluvial environment. He has also broad experience in WFD implementation and in the use of biotic indexes for ecologic status assessment. [ResearchGate]

 Rafel Rocaspana

PhD Biology. Specialized in freshwater icthyology and environmental aquatic management, he has developed projects related to ichtyofauna management and characterization of the ecological status quality of water bodies. Also has a large experience in environmental evaluation, environmental studies related to hydraulic infrastructures and exploitation of natural resources. [ResearchGate]


 Roger Guillem

BSc Biology. Specialized in environmental studies, vegetation and habitat cartography, park and garden vegetation inventories, census and conservation of birds life of drylands and landscape studies. He has taken part in studies about environmental evaluation, aquatic environmental management, ecological status determination and studies of continental ichtyofauna.
