Xiangjun Tian (xiangjun.tian@wustl.edu)

Xiangjun Tian received his PhD in 2006 from the Zheijang University in Hangzhou, China. He is currently working on the comparative genomics of social amoebae, based on whole genome sequencing and next-generation RNA sequencing data in order to answer the following questions: Does variation during the multicellular developmental stage (or social stage) of Dictyostelids follow von Baer’s law or the hourglass model? Does the evolution of prestalk and prespore genes follow evolutionary mechanisms similar to those of somatic cell and germline cell genes within complex multicellular organisms? In his previous work, he discovered that social genes evolve faster than vegetative genes. Second, he discovered that high AT content of  genome sequences drives the high frequency and density of microsatellites in Dictyostelium.
