Research Interest:

 

I have developed a high-throughput microvolume DNA extraction method for studying microbe to microbe interactions at community-level to shed light on cross kingdom microbial interactions in the ocean. Currently, I am trying to integrate dynamics of the prokaryotic communities during phytoplankton bloom in nature and stages of experimentally simulated bloom in a 96‑well microcosm platform.

In general, I am interested in deciphering interactions between host and microbiome and within microbiome. Understanding how host attracts and retains its microbiome, and how microbe-microbe interactions further shape associated microbial communities can contribute to our understanding of holobiont’s performance/resistance/defense, which can have implications for environment and human health.
