Group leader

 

Dr. LI is a professor and principal investigator at Beijing Institute of Genomics (BIG), Chinese Academy of Sciences (CAS). Dr. LI received the B.S. and M.S. degrees in Biology from Northwest A & F University, Shannxi, China in 2006. He received a Ph.D. in Bioinformatics/Genetics from Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany in July 2012 (advisor: Dr. Mark Stoneking), and did postdoctoral research in the same lab until Oct 2013. He held a position as Senior Scientist/Bioinformatics Group leader at Fondation Merieux, Lyon, France before joining BIG. Dr. LI's expertise is bioinformatics, metagenomics, and molecular evolution.

 

Introduction

 

LI lab is currently focusing on two topics:.

 

1. lung microbiome

The lung is relatively sterile compared to the gut; however, the importance of the lung microbiome in health has been well recognized. Alternation of the lung microbiome has been associated with clinical and inflammatory features of several respiratory tract diseases, thus making it a potential target for novel diagnostic and therapeutic approaches. However, the baseline of the lung microbiome is still largely unclear, especially for non-Caucasian populations. The group is trying to answer the following questions:
What is the core microbiome in the lung?
How the lung microbiome alter during infection?
How microbiome differs between lower respiratory tract and upper respiratory tract?
How microbiome interacts with the host gene expression?
How the viral genome evolves after infecting human?

 

2. Mitochondrial DNA

Mitochondrion has its own genomic DNA(mtDNA), that has thousands copies in each cell. Its mutation rate is about 10 times higher than that of nuclear DNA and very few recombinations were observed on mtDNA(maternal inherited), thus making it a frequently-used molecular biomarker in population genetics studies. Meanwhile, mtDNA mutations are known to be associated with several inherited diseases, and these pathogenic mutations as well as other "neutral" mutations are normally in heteroplasmic states (a mixture of wild type and mutant type), which is hard to be detected by ordinary method. With the development of Next-generation Sequencing, it is feasible to identify many low-level heteroplasmies, thus enable us to reexamine the fundamental theory of mtDNA inheritance, including:
Whether paternal leakage exists during mtDNA inheritance?
Whether recombination occurs on mtDNA?
Whether the mtDNA mutation pattern differs between cell line and fresh tissue?
We are collaborating with Max Planck Institute and Genome of the Netherlands consortium on this work.
