P08: MeDIP analysis using R

Short Title: MeDIP analysis using R
Mentors: Dr. Karin Dorman
Description:

MeDIP is a technique for identifying CpG methylation status in genomes.
Methylation status is an epigenetic (non-genetic, but sometimes heritable) change that impacts phenotype, including disease/cancer.  Here, we propose to develop methods to handle the CpG methylation status dependence structure along the genome.  The dependence is caused by experimental (probe or sequence read
overlap) and biological (sequential methylation) reasons.


Expected results:
- Build a new R package.
- Develop an improved method for detecting differentially methylated CpGs.
