Research Interests

Our research spans a broad range of Microbiology, Microfluidics, and Bioengineering.  We are developing microfluidic tools to explore and understand the diversity and functions of microbial communities.  We use droplet microfluidics for high-throughput screening using single bacterial cells in nanoliter to picoliter volumes. Our goal is to realize single bacterial cell acquisition, cultivation, manipulation and identification in an integrated and automated workflow.  Using these platforms, we are interested in the isolation and detection of rare microbes and extremophiles from the environment, and we are also applying them on early diagnosis of rare pathogen infection.  We are also intested in further development of “Lab-on-a-Chip” systems for microbiological research, specifically in the integration of fluidic regulators, detectors, imaging systems, and interfacing microfluidic devices with instrumental analysis methods.

Our current ongoing projects include:

  1. Single cell isolation and cultivation in droplet array
  2. Bacterial chemotaxis in microfluidic devices
  3. isolation and multiplex PCR identification of bacterial cells from clinical samples
  4. Interface microfluidic macromolecules separation with MALDI-TOF MS
