Profile Summary

I am a physicist with expertise in quantum physics, thermodynamics, and statistical mechanics. As a Marie Skłodowska-Curie Postdoctoral Fellow at Trinity College Dublin, I developed a novel approach to the thermodynamics of quantum systems based on scattering theory (SAT-Q), aiming to bridge fundamental physics with real-world applications and emerging quantum technologies. My academic journey spans multiple disciplines: I hold a PhD in Physics (University of Luxembourg), an MSc in Bioengineering and Nanosystems, and a BSc in Biochemistry. This interdisciplinary background gives me a broad scientific perspective across physics, technology, and the life sciences. I have published in high-quality journals, including Physical Review Letters, and was selected to participate in the Lindau Nobel Laureate Meetings, recognizing my contribution to science and potential as a young researcher. Throughout my career, I have developed strong skills in technical and academic writing, literature review, grant writing, and scientific communication. I am multilingual (Portuguese, English, Spanish, French, and German) and passionate about making complex ideas accessible to expert and non-expert audiences alike.
