Overview


We have broad interests in using microbial genomics to understand how microbes interact with each other and their hosts. This interest includes the roles played by both beneficial and harmful bacteria, fungi, and viruses and how they interact with the immune system. We study single microbes and microbial communities, primarily using high-throughput sequencing methods. We have a particular interest in developing new experimental and analytical methods that leverage the power of high-throughput sequencing. We are also interested in using deep learning in microbiology research.

From external-input sensitivity to resident persistence: community assembly in a sink p-trap model.

Preprint · May 14, 2026 Microbial habitats that receive repeated external input may not remain shaped by that input forever if local retention allows resident communities to build up over time. Here, we used a controlled bench-scale sink p-trap system to examine how community ass ... Full text Link to item Cite
