Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Carcinogenesis is an evolutionary process in which advantageous mutations accumulate over time and cells harboring these mutations give rise to new clones. The nature of this progressing disease makes time course analysis very difficult and therefore the composition of these clones is generally unknown. We will discuss methods designed to identify intratumoral cancer clones with different sequencing paradigms, namely bulk and single-cell sequencing. A common foundation of the methods is Bayeisan nonparametrics, by which the number of clones can be inferred in a principled framework.
Bio:
Ke works on statistical methods for quantifying breast cancer mircoenvironment from tumor images. His goal is to build probabilistic decision making machines to predict clinical outcomes (survival, relapse, etc), based on empirical features extracted from both tumor images and the associated molecular profiles (gene expression, copy number, etc).
