Eyal started a one-year sabbatical in University College London, hosted by two hosts: Ziheng Yang and Seirian Sumner. The Yang lab develops methods in molecular evolutionary analysis, including (in the more distant past) dN/dS method for the inference of positive selection and (more recently) pop-gen methods for species delimination and demographic inference. The Sumner lab studies the evolution of Hymenptera (all kinds of wasps!) using evolutionary and functional genomic approaches, among others. Interaction with both groups has great potential for collaboration.
