Guest intro
David Tsao is Co-Founder and CTO at BillionToOne, a biotech company valued at $4 billion that has developed a DNA molecular counting platform for prenatal and cancer detection. He holds a PhD in bioengineering from Rice University, where he was awarded a Nanobiology training fellowship, and earned his bachelor’s degree in Physics, cum laude, from Princeton University with minors in Biophysics and Engineering Management Systems. As the original inventor of BillionToOne’s core DNA molecular counting technology, Tsao has presented the company’s clinical trial results at national medical conferences and helped transform the company from a half lab bench into one of the most widely used prenatal testing platforms in the US.
