November 17 SFASA Seminar
Berkeley Genomics Seminar Co-Sponsored by the SF Bay Area Chapter of the American Statistical Association
Title: Normalization and Differential Expression in RNA-Seq
Speaker: Sandrine Dudoit, Professor of Biostatistics and Statistics Chair, Graduate Group in BiostatisticsUniversity of California, Berkeley
Location: 1011 Evans Hall
Time: Nov. 17th Thursday 4-5 pm
This talk concerns statistical methods and software for the analysis of RNA abundance by sequencing (RNA-Seq). We first present exploratory data analysis (EDA) approaches for quality assessment/control (QA/QC) of RNA-Seq reads. Next, we propose within-lane normalization methods to adjust for sample-specific gene-level effects such as length and GC-content. We also provide between-lane normalization procedures to account for distributional differences such as sequencing depth. Finally, we consider the quantitation of (differential) gene expression levels using generalized linear models (GLM). This work was motivated by a collaboration with the Sherlock Lab on transcriptome analysis in Saccharomyces. Our exploratory data analysis and normalization methods are implemented in the open-source Bioconductor R package EDASeq (http://www.bioconductor.org/ ).

4) Public transportation to UCB campus:
BART @Downtown Berkeley station (Exit the Berkeley station at Center Street. Walk east on Center Street for 1 block to the campus)
AC Transit: several AC bus lines that stop at the campus at the intersection of Bancroft Way and Telegraph Avenue such as lines: #1; #1R; #7; #49; #51B; #52; and F.
The SF Bay Area Chapter does not schedule a seminar in December. However, this year, we have arranged to co-sponsor a seminar with Stanford Biostatistics on Thursday December 1 from 1:15 to 3:00 pm.
