How I am inventing the future of medicine

Our lab focuses on development of a new class of low cost point-of-care diagnostic technologies utilizing microfluidics, particularly paper-based systems imaged by cell phones, with a long range goal of increasing access to healthcare in the developed an developing worlds. We are hoping to help to commercialize these technologies in the near future with partners outside of UW.
Research Interests

Nucleic acid assays
Microfluidics 2.0
Point-of-care diagnostics
Global health
Translational medicine.
Research Description

The two major projects in the lab at this time focus on the use of what we call two-dimension paper networks (2DPNs):
1) Development of paper-based immunoassays for pathogens like the influenza virus that have enhanced sensitivity
2) Development of the first instrument-free point-of-care technology for sample-to-result detection of pathogens using isothermal nucleic acid amplification.
Both projects involve collaborations with multiple organizations, including industry. Work in the lab includes physical biochemistry, immunoassay development, materials science, development of optical methods for sensitive chemical detection, nucleic acid amplification, microfabrication, cell-phone imaging, and computational fluid dynamics.
