Research Description

Microbes carry out much of the chemistry that sustains life. They shape ecosystems, influence human health, and enable modern biotechnology. Advances in DNA sequencing now allow microbial genomes to be read at massive scale. Yet for most microbes, we still cannot reliably predict their functions, explain their behavior in communities, or engineer them. The central challenge is no longer data collection, but converting genomic information into mechanistic and predictive understanding.

Our research program addresses this challenge by building systematic experimental platforms to measure microbial behavior and applying quantitative modeling to extract general biological rules from these data. Because the space of genetic variation and environmental conditions is far too large to explore exhaustively, models guide experiment selection and hypothesis generation. The lab operates in an iterative cycle of experimentation, modeling, and validation, with the biological goal of understanding how microbial genetic variation shapes colonization, metabolism, and host interaction.

My past work established the key tools for this approach, including mapping microbial evolution within hosts, developing single-kdpay钱包(中国) and spatial genomics to resolve strain organization in complex communities, and constructing large living strain collections for controlled perturbation. Together, these foundations support a research program that moves microbiome science from descriptive surveys toward causal and predictive biology. We pursue three integrated research directions:

1. Predictive maps of microbial behaviors

We will quantify how tens of thousands of microbial strains grow, interact, and adapt across diverse environmental and host-relevant conditions. These experiments will generate quantitative maps linking genetic variation to regulatory control, metabolic state, and ecological fitness. The outcome will be predictive frameworks for how strains and communities respond to perturbations such as dietary change, drug exposure, or host physiological shifts.

2. Discovery of molecular functions from nature’s dark matter

Microbial genomes contain vast numbers of genes whose functions cannot be reliably inferred from sequence alone, leaving much of microbial biochemistry unexplored. Testing this space with synthetic DNA libraries remains costly and limited in scale. We exploit natural strain diversity and large living strain collections as a cost-effective and information-rich alternative. By pairing these resources with functional screening, we aim to uncover new molecular activities in small-molecule biosynthesis, plasmid maintenance, phage resistance, and host-associated functions. These discoveries will define sequence–function relationships and provide mechanistic entry points for biochemical and genetic investigation.

3. Engineering previously intractable microbes

Many microbes that dominate human-associated ecosystems remain inaccessible to genetic manipulation. Progress requires not only developing new tools, but first uncovering the biological principles that govern how these organisms interact with foreign genetic material and regulate genome stability. We will therefore combine investigation of genetic elements, plasmid compatibility, and host restriction systems with systematic development of DNA delivery and editing strategies. The outcome will be broadly applicable genetic platforms that enable direct testing of gene function and controlled perturbation of microbial pathways within complex communities.
