I am a PhD student in Health Sciences at ICVS, with a research focus on neuroscience. I have a bachelor’s degree in Applied Biology (School of Sciences, University of Minho), having worked briefly in the field of oncology studying the role of WNT6 in a murine in vitro model of glioblastoma during my internship project.
I completed a master’s in Health Sciences (School of Medicine, University of Minho), having defended my dissertation – “Valence in the Nucleus Accumbens – Identifying Neural Populations in Appetitive and Aversive Responses” – under the supervision of Ana João Rodrigues and Carina Soares-Cunha. I studied how neuronal populations in the nucleus accumbens and amygdala subnuclei respond to positive and negative valence stimuli – a topic I am still exploring. For this, I use anatomically-detailed immunofluorescence and behavioural assessments (such as place preference tests) combined with aversive and appetitive stimuli and optogenetics. More recently, my work also involves implementing a variety of high-throughput techniques (proteomics, single cell RNA-sequencing, calcium imaging) to more comprehensively study this topic. Our team’s work allowed for co-authorship in 4 published journal articles (Cell Reports, IF: 7.5; Translational Psychiatry, IF: 5.8; Journal of Neurochemistry, IF: 4.2; Journal of Psychiatry & Neuroscience, IF: 4.1) and in two posters presented at the international FENS Forum 2022.

Sensory signals of associative learning

Through evolution, animals gained the remarkable ability to respond with sub second precision to environmental stimuli and to learn to associate those with positive or negative outcomes…
