Computational and evolutionary genomics

High-throughput sequencing is allowing the genome, transcriptome and epigenome of an enormous range of species, including model and non-model organisms, to be studied in exquisite detail. Moreover, as technology develops further, we will move from studying populations of cells to studying regulatory processes at the single-cell level - this will enable numerous insights into developmental processes (e.g. embryogenesis and early-development), neurological processes (e.g., a fine-grained map of gene expression within specific brain regions), and the way in which tumours develop. However, to make the most of these opportunities, appropriate computational tools for managing, analyzing, visualizing and downloading the data are essential. With this in mind, our work focuses on the development of statistical methods that will exploit these data to the fullest extent.
