Our lab is pioneering the development of advanced diagnostic devices capable of ultrasensitive, quantitative biomarker measurements. Such technologies are poised to revolutionize medicine—providing rapid point-of-care (POC) diagnoses under a variety of settings outside of clinical labs.

One area of active focus in our lab is developing tools capable of rapidly detecting antibiotic susceptibility. The liberal use and misuse of antibiotics has led to an impending global health crisis: the widespread development of antibiotic resistance. Prescribing correctly and achieving antibiotic stewardship both critically depend on health care providers learning the results of an antibiotic susceptibility test (AST) during a patient's visit. Such a test simply does not exist—even in hospital settings. Development of a rapid POC AST was selected for the Longitude Prize as the most urgent science/technology challenge facing humanity, ahead of all other challenges in energy, environment and health.

How do we make quantitative, ultrasensitive molecular measurements accessible to anyone, anywhere?

How do we genotype viruses, measure viral load, and detect antibiotic resistance under limited-resource settings?

How do we create devices/architectures that can be operated by untrained users, without a lab or equipment?

What are the mechanisms of single-molecule amplification reactions; how do we design robust amplification schemes?

How can we detect critical biomarkers at unknown (very high to very low) concentrations?
