Studies microbial ecosystems to improve water supply safety and public health


Fangqiong Ling leads a computational and experimental lab to study bacterial colonization and transmission at the boundary of built and natural environments. She explores microbiomes as environmental sensors and public health sentinels.


Her research employs genomics, machine learning and theory. The lab’s ultimate goal is to discover the principles underlying the diversity, functioning and resilience of microbial ecosystems and develop tools to enable ecologically aware designs. Current research topics and interests include:

  • Assembly, structure and dynamics of bacterial communities in tap water and water supply networks
  • Biodiversity and ecosystem functioning in biofuel production processes
  • Development of population matrices based on personal microbiome data
  • Development of tools to tackle hospital-acquired infections


Fangqiong Ling joined the WashU faculty in August 2018. Prior to joining WashU, Ling was a postdoctoral fellow at MIT supported by the Alfred P. Sloan Foundation Microbiology of the Built Environment Postdoctoral Fellowship. She received the Powe Award for Junior Faculty Enhancement by the Oak Ridge Associated Universities (2019), the ISME/IWA Biocluster Rising Star Award (2020), and the National Science Foundation CAREER award (2021). She serves as an Associate Editor of Water Research and an editorial board member of ISME Communications.
