Venture Café – Lan Yang, PhD and Chao Zhou, PhD ~ The Light Fantastic: Moving innovative optical medical diagnostic technologies from concept to marketplace

January 21, 2021
4:00 pm - 4:45 pm

Precision Medicine Thursdays at Venture Café
Attendance is FREE and open to all.


Lan Yang, PhD
Edwin H. & Florence G. Skinner Professor of Electrical & Systems Engineering

The magic of light in medical diagnosis: from ideas to technology development

I will talk about a chip-scale sensor that could achieve not only detection of single nanoparticles but also size analysis, which will provide additional exclusion criteria based on virus size for pathogen/antigen and infection detection. With the combined features of single-virus particle resolution, high sensitivity, small size, low cost and easy integration with existing electronics for point-of-care applications, the novel sensors have a great potential as a valuable tool for early disease diagnosis, pharmaceutical testing, and medical research. Our efforts in lightwave technologies have led to a startup aiming to develop advanced diagnostic tools.

Associate Professor of Biomedical Engineering

Ultrahigh-speed Optical Coherence Tomography (OCT) 

Optical Coherence Tomography (OCT) is a widely used diagnostic imaging tool for eye diseases. We developed a parallel imaging OCT technology, which achieves over 10-fold speed improvement compared to the state-of-the-art commercial devices, enabling high-definition 3D imaging of the human retina in 1s.


On the third Thursday of every month, ICTS Precision Medicine hosts a session featuring WashU faculty working in translational genomics/precision medicine areas. Talks are typically oriented toward biotechnology, diagnostics, informatics, start-ups and precision interventions based on medical genomics innovations.
