Xiao completed two year postdoctoral training at the Wang Genomics Lab and took on a second postdoc at CHOP/Penn. Xiao came to the lab as a ZNI Young Scholar, and he worked on developing a web interface for ANNOVAR software (wANNOVAR), as well as the properties of 'party' and 'date' hubs in protein interaction networks via systems biology approaches. Best wishes to Xiao!
