Current Research Interests
The genetic and genomic changes underlying weedy plant evolution. The evolution of wild relatives of important economical species.
Our lab is interested in any topic broadly related with evolutionary and ecological genetics and genomics, specifically, how do genes, genomes, environments, complex traits, and natural selection interact with and shape the patterns of each other? What is your favorite species? Let's explore the interesting story behind it!We use a highly integrative and interdisciplinary approach for our research, incorporating knowledge and techniques in field ecology, population genetics, quantitative genetics, molecular biology, genomics, and bioinformatics. Perspective students are expected to be enthusiastic about evolution. Having prior knowledge of any of these fields is great, but not necessary.We are interested in (but not limited to) these important questions:
Does local adaptation facilitate speciation?
Why is there genetic variation, and what maintains it?
What are the factors shaping geographical patterns of genomic variation?
Some genomic regions are more polymorphic than others. Why?
What are the genomic regions or genes controlling adaptive traits?
Are they few genes each with large effect, or many genes each with small effect?
Does the adaptive allele come from novel mutation or standing genetic variation?
In addition, we are also interested in the evolution and relationship of human-associated plants with their wild relatives, including the weed Arabidopsis thaliana and economically important species such as rice and soybean. Our group highly welcome those who are interested in ecological and evolutionary genetics and genomics!
