About me

I am a researcher in the Area of Biodiversity and Conservation interested in the effects of climate change on marine benthic species. I work at the interface of coastal ecology and biogeography, integrating spatial analyses with field and physiological experiments.

Research Lines

Mechanistic models applied to climate change studies

There is a need to integrate physiological data better to improve the prediction of future distributional shifts at local and regional scales. My current research is mainly linked to MarHot and Phymacro European Union’s Horizon 2020 funded projects and it is focused on the integration of physiological experiments with SDMs to investigate further mechanistic models taking marine foundational algae and kelps as model species. I will develop open software in R to make the mechanistic framework reproducible for all scientists.

Patterns of genetic diversity and range shifts of marine species

My post-doctoral project INTERSEA allowed me to investigate the response of marine species to environmental changes, integrating spatial analysis, niche modelling, and genetic data. This project was developed while I was FCT postdoctoral researcher and Research Assistant afterwards at the Centre of Marine Sciences (CCMAR; University of Algarve, Portugal). I analyzed the predicted effects of climate change on the loss of genetic diversity of seagrass and seaweed populations. I used reconstructions of Last Glacial Maximum climate to identify past coastal regions acting as glacial refugia and areas of persistence, revealing now genetic signatures that are the result of accumulated genetic diversity.

Invasion process and prediction of invasion risk

I have paid particular attention to the study of invasive species by focusing on the effects of invasive species on the composition of communities, also by modelling their niche shift and future risk of invasion.

Spatial and temporal dynamics of coastal communities

In this research line, I have incorporated field work of diverse coastal environments (dune habitats, saltworks, etc…). I explored a better understanding of the spatial variation of community composition data. The data compiled during these campaings will result in several publications on spatial variation in abundance both in marine and terrestrial realms.
