Data Challenge "Epigenetic & High-Dimension Mediation"

from June 7, 2017 to June 9, 2017

From 11 am to 12am
Progresses in high-throughput sequencing make it possible to study how epigenetic changes mediate the effect of environmental risk factors on diseases. Epigenetic changes are said to be mediators when they intervene in the causal pathway between environmental exposures and diseases.
We will provide the necessary background to participate to the Data Challenge, which includes introductory lectures and demo in R about multiple hypotheses testing, epigenome-wide association studies (EWAS), and statistical mediation analyses. To promote collaboration between participants during the Data Challenge, we will show how to share source codes using R notebooks and github.

  • Participants will have the opportunity to present their own research during poster sessions.
  • Participants should bring their own laptop in order to be able to participate to the Data Challenge.

Who can attend?

Researchers or students interested in mediation analysis in a multi-dimensional setting are welcomed. The data challenge is open to researchers from various backgrounds (statisticians, epidemiologists, biologists, physicists). The data challenge concerns mediation analysis in epigenomics but the statistical concepts we introduced are also relevant for other multidimensional data.

We expect that participants are familiar with the R software and with standard statistical notions such as linear regression, and P-values.

Where and when

The challenge will take place during 3 full days (June 7-9th, 2017) in Aussois, Vanoise. It will end at 5pm on June 9th. Except if you leave nearby (Grenoble or Lyon), it is recommended to arrive in the conference center on June 6th at dinner time. Housing can start on June 6th or June 7th. If you want to leave Aussois on June 10th, you should spend the last night in another hotel nearby (e.g. hotel des mottets).

The summer school will take place in Aussois, a charming small village in the Vanoise National Park (French Alps). The remote setting, along with the challenging program, were chosen to promote and enhance interactions between participants.
