Research Interests:

In my dissertation I proposed a Bayesian hierarchical model to make inference about species trees and I wrote a program BEST (Bayesian Estimation of Species Trees) in C language to implement the model. In my postdoc, I continue to extend the Bayesian hierarchical model I proposed for estimating species trees in my dissertation. The research will first incorporate multiple alleles feature in the current model to improve the estimation of ancestral population sizes. I will then construct an efficient algorithm to search for the Maximum Likelihood estimate of the species tree.
