Research Interests

My research program seeks to elucidate the ecological and evolutionary mechanisms that confer adaptation to environmental change in plants. Using crop relatives (wild strawberries and apples), our lab addresses eco-evolutionary adaptation through the lenses of functional ecology, genomics and microbiome.

Current Projects

Ecological adaptation to environmental change

  1. How do functional traits and trait plasticity confer polyploid advantage?
  2. How does plant microbiome mediate polyploid advantage in response to environmental change?

We explore these questions using manipulative experiments, synthetic microbial communities, and sequencing.

Eco-evolutionary dynamics of plant–microbiome interactions

  1. What are the principles governing microbiome assembly and network in plants?
  2. What are the functions of plant microbiome (e.g. stress tolerance, disease resistance, nutrient acquisition, pollination)?
We explore these questions using field work, tissue culture, microbiome selection and inoculation, and experimental evolution.

Genomics of adaptation

  1. What is the genetic architecture of ecological adaptation to environmental change?
  2. How does genetic variation shaped by past selection influence adaptive responses to future environmental scenarios?

We explore these questions using RNA-seq, RAD-seq and whole genome sequencing.
