I am a PhD student in Health Sciences with a bachelor’s degree in Human Biology from the University of Wroclaw, Poland, and a master’s degree in Neuroscience from the University of Trieste, Italy. During my master’s I investigated opioid release in the reward system. Currently, my PhD project focuses on how these endogenous opioids regulate neuronal circuits involved in reward and aversion, particularly within the nucleus accumbens and ventral tegmental area. My primary experience lies in animal behavior, where I use various genetic and pharmacological modulations as well as fiber photometry. Additionally, I have gained experience in whole-brain analysis and microscopy to further understand reward circuitry. I will soon begin an exciting new phase of my PhD at Washington University, where I will continue to explore opioid-driven mechanisms in motivated behaviors.
Throughout my scientific career, I have presented my research at various scientific events through posters and presentations. I am also a co-author of 2 papers, in collaboration with my colleagues. As an active member of the ICVS Well-being team, I am engaged in organizing events to promote mental health and well-being at the institute.
