I am a PhD researcher at the ICVS, University of Minho in Portugal with a background in Biology and a Masters and PhD in Health Sciences.
My main research focus in the study of the role of the laterodorsal tegmentum (LDT) in motivation and reward processes in natural conditions (place and food seeking/preferences or avoidance behaviors) and in context of disease (as depression or drug addiction). I am studying LDT projections and its integration in neuronal networks related with motivation/reward through the combination of behavioral, neurochemical, electrophysiological, optogenetic, imaging and molecular biology correlates.
I published several papers as first author, in peer-reviewed scientific journals with a high impact factor and have published several others as co-author as a result of collaborations with colleagues and other research groups. I supervise master and undergraduate students. In addition, I actively participate as teaching staff in several post-graduate and advanced courses, outreach activities to the general public by volunteering in the “brain awareness week”, “Open Laboratories” and “Summer in Campus” at the University of Minho.

Brainstem orchestration of cue-reward associations

The brain constantly integrates new sensory information, and associates environmental cues to outcomes, adjusting behavior to maximize reward and minimize unpleasant consequences. This process is critical for survival, and its dysregulation is a hallmark of…
