I am now an assistant investigator in Yong’s lab. The research I am working on is the origin and evolution of new genes within species. We want to figure out the molecular mechanism of new gene burst, the fate of these new-born genes and the evolution forces behind it. It is a very interesting and also changeling program.

  • Project: high-throughput cloning resistance genes from rice species

Developed a new way to quickly and effectively clone functional genes resisting blast disease in rice. I am responsible for transforming R genes into rice genomes in this project.

  • Thesis Research: investigating the universal trend of codon and amino acid evolution

An investigation in the codon and codon-pair usage and amino acid changes using bioinformatics
