Abstract:
|
Single cell CRISPR screens, pairing CRISPR perturbations of regulatory elements with single cell RNA-sequencing, are an emerging biotechnology promising unprecedented insights into gene regulation. However, the analysis of these screens presents significant statistical challenges. Some of these challenges are inherited from single cell RNA-seq, such as cell type heterogeneity and noisy expression measurements; others are specific to CRISPR experiments, such as the fact that the identities of the CRISPR perturbations a given cell receives are subject to measurement error. In this talk, I will discuss these challenges and present a recent line of work whose goal is to construct reliable hypothesis tests and confidence intervals in this setting.
