Research Interests

I have a background in Evolutionary Biology/Neuroscience being interested in understanding behaviour as a biological phenomenon driven by the constant and evolutionary factors that influence structural and ethological adaptations. I believe that the combination of these approaches is fundamental, focusing on questions such as why and how behaviour is generated, the manner in which the environment influences behaviour, and the neural and physiological processes that underlay it.

My main topic of research interests focus on the understanding of complex behavioural adaptations as explained by the structure and function of their brain processes and principles of evolutionary biology.

My research aims to identify key neurons and functional properties of the song pattern generating system (CPGs) in crickets with very different song patterns (Gryllus bimaculatus, Gryllus assimilis and Gyrllus rubens). This comparison will bring us a step closer to know if the species-specific song patterns are based on changes in the network architecture, connections between particular neurons or membrane properties of individual neurons. These findings can shed a light on how sexual selection altered the cricket singing CPGs, and hence the nervous system, to allow species-specific signalling.
