Poly Hannah da Silva is an Associate Research Scientist in the Department of Statistics and the Irving Institute for Cancer Dynamics. Her primary areas of interest include probability, discrete mathematics, graph theory, and algorithms with their applications in population genetics, genomics, cancer, and phylogeny reconstruction. Her current research focuses on the development of statistical and probabilistic methods to understand various aspects of cancer and molecular evolution. This involves developments in the theory of birth-death immigration processes with clonal selection, models incorporating time-varying mutation rates for analyzing biologically-related data, studying evolutionary dynamics in structured populations, as well as comparative genomics and phylogenetics to investigate cancer evolution.
