Emrah Kostem’s talk about his research

Emrah Kostem, who graduated this year and is now at Illumina, gave a talk about the research he completed in the lab this summer at our retreat.  It is available here and gives a good overview of what the goals of our group are and some details of the projects that Emrah completed in the lab.

One of the topics he discusses is his recently published work on estimating heritability, which is quantifying the amount that genetics accounts for the variance of a trait.  He discusses his work on how to partition heritability into the contributions of genomic regions(10.1016/j.ajhg.2013.03.010).

He also talks about his work which takes advantage of the insight that association statistics follow the multivariate normal distribution and applies this to two problems.  The first is the problem of selecting follow up SNPs using the results of an association study(10.1534/genetics.111.128595).  The second problem is the problem of speeding up eQTL studies using a two stage approach where only a fraction of the association tests are performed but virtually all of the significant associations are still discovered(10.1089/cmb.2013.0087).

Details of what he talked about are in his papers:
