Having originally studied microbiology, I accidentally transitioned into the human genomics field at the end of my undergraduate studies, while looking for opportunities to work with large-scale DNA sequencing data. Since then, what was supposed to be a one-year thesis project has turned into a ten-year venture seeking to understand human phenotypes through the lens of inherited and somatic genetic variation. By harnessing new molecular data across ever-growing cohorts, I aim to build a detailed map of how the human body works and interacts with its environment, and of what disease looks like in each person, one molecule and one cell at a time.
