Post Doctoral Researcher SeaDNA

I grew up in Almeria (Spain), a small Mediterranean town close to Cabo de Gata Natural Park, one of the few nearly untouched coastal areas remaining in Southern Europe. Despite being a natural-born marine naturalist, I sought for the elementary underlying mechanisms of life and I first specialized in Chemistry at the University of Granada (Spain), where I got a PhD degree in biochemistry and molecular biology (1999). Later, I returned to my real passion: marine invertebrates, by moving to the University of Barcelona (Spain) and pursuing a BSc in Biology (2008), a MS in Animal Biodiversity (2009) and, finally, a PhD in marine invertebrate biology (2013). After that, I worked for the Spanish Research Council (CSIC), introducing next-generation sequencing techniques for eukaryotic biodiversity assessment (metabarcoding). In 2016 I moved to the University of Salford to become a member of the SeaDNA Project, a project aimed at developing new molecular techniques for biodiversity assessment in marine environments.

 

Research interests:

 

I define myself as a molecular marine ecologist. Thus, I am kind of a “bipolar” biologist, who thinks on whole organisms and their populations as functional actors of the ecosystems, while my molecular background makes me think analytically on the subjacent genetic endowments which allow them to survive and thrive in a changing world, and on how can we study these genetic treasures for understanding the processes that are shaping organisms, populations, communities and ecosystems.

 

Recently, I have turned my main focus on molecular biodiversity assessment of marine ecosystems using eukaryotic metabarcoding. This is a promising technique that will allow us to ultimately describe and objectively quantify the real biodiversity hidden in a given community. The future applications of this technique will be enormous: ranging from analysis of water quality or monitoring changes in natural communities to early detection of non-native species introduced in the ecosystems. All of this, using a faster, less expensive, more repeatable and less subjective technique than current morphological assessment. It is such an exciting field to work on!
