I’m a computer vision and machine learning software engineer at Chan Zuckerberg Biohub, where I develop methods and tools for processing terabytes of microscopy data. I obtained my MSc in Computer Science and BSc in Statistics from the University of Campinas, Brazil. During that time, I spent four wonderful years doing research at LIDS under the supervision of Prof. Alexandre Falcão. In 2019-2020, I was fortunate enough to do a research internship at LIGM under the supervision of Prof. Laurent Najman.
