Cancer results from an evolutionary process that causes the development of clonal populations within a tumor. Deconvolving DNA sequencing data to infer clonal populations is an open problem in bioinformatics. In my undergraduate thesis, I developed a generative Bayesian graphical model with a Dirichlet process prior to describe this process with respect to variant allele frequencies obtained in bulk sequencing. I proved a theoretical result that a vectorized version of the Dirichlet process is also in the exponential family, and derived a variational inference algorithm to compute maximum a posteriori estimates of clonal populations and their mutation frequencies.
