Flaherty in MLFL Thurs. Sept. 14 at noon

Pat Flaherty (UMass Math) will present “A Nonparametric Bayesian Model For Single-cell Variant Calling” in the Machine Learning and Friends Lunch Thursday Sept.. 14 from 12:00pm to 1:00pm in CS 150. Abstract and bio follows.

Abstract:

Advances in DNA sequencing technology have enabled surprising discoveries in basic science and novel diagnostics in personalized medicine. Recently, the ability to read the DNA sequence of a single cell has presented new statistical and computational challenges. We address the problem of calling single-nucleotide mutations in single-cell sequencing data. We present some results evaluating existing mutation calling algorithms on data generated from a single-cell sequence data simulator. We describe a nonparametric Bayesian generative model for combining single-cell and bulk DNA sequencing data, and we show preliminary results from this model.

Bio:

Patrick Flaherty is a Professor in the Department of Mathematics & Statistics at UMass Amherst. He received his PhD in Electrical Engineering and Computer Science from the University of California, Berkeley and he was a postdoctoral scholar at Stanford University in the Department of Biochemistry. His research focuses on scalable, statistical methods for analyzing large genomic data sets.
