    Collapse Overview 
    Collapse overview
    I'm interested in collaborating with other researchers.

    My research group specializes in microfluidics and other microfabricated devices. Our current technologies include:
    * Single-cell positioning and assembly
    * Single-cell transfection
    * Cell sensing and measurement
    We are also interested in developing new technologies to address specific biological questions.

    PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
