My PhD thesis focuses on cancer research and specifically in gaining insights over complex biological data. The goal of the thesis is to recover novel patterns of cancer initiation and progression. This work includes rigorous data curation over large datasets to exclude non-cancerous noise, and the development of machine learning models to extract statistically significant patterns. To date, a total of 42 non-reported mutational patterns have been recovered, using state-of-the-art machine learning pipelines.
