My research focuses on microbial community ecology, with particular emphasis on the mechanisms governing community assembly and the maintenance of microbial diversity. By integrating large-scale database analyses with independently generated high-throughput sequencing data, I investigate community assembly patterns at macroscopic and cross-environmental scales. In parallel, I employ laboratory-based microcosm experiments, combining top-down community simplification and bottom-up synthetic community construction, to validate and mechanistically dissect the key ecological processes underlying community assembly and long-term stability within controlled systems.
