The Pangea Team

COVID-19 PCR Testing at Pangea

Pangea Team​

At the core of Pangea Laboratory is not just innovative technology or state-of-the-art facilities; it is our group of passionate individuals who are deeply committed to redefining the future of healthcare diagnostics. Our team is a blend of visionary scientists, dedicated technicians, and compassionate healthcare advocates with a shared purpose: to ensure that every individual has uncompromised access to the best of non-invasive medical testing.

Our journey began with a simple but profound vision: to bridge the diagnostic chasm that exists across various communities. We realized that for healthcare to truly be inclusive, diagnostic solutions needed to be not just accurate but also accessible and convenient. That’s why our team has poured countless hours into developing groundbreaking remote sample collection methods and pairing them with innovative non-invasive testing solutions in the fields of oncology and infectious disease.

As we move forward, our goal remains unwavering: to democratize healthcare and make it more human-centered.

Larry (Xi-Yu) Jia
MD – Founder & Chief Executive Office

Dr. Jia received his medical degree from Suzhou Medical College, China in 1982 and his Masters in Microbiology from the Institute of Virology, Chinese Academy of Medical Science in 1986. He served as Deputy Chairman of the Institute of Virology before relocating to the USA.

After postdoctoral training in Virology at the University of Utah, he joined the University of California, Irvine faculty where he held numerous research and teaching positions as a virologist.

Among Dr. Jia’s notable contributions to the field of virology was his discovery of the West Nile virus in North America in 1999, highlighting the direct impact of his research on public health.

Dr. Jia founded Pangea Laboratory in 2014 and serves as CEO. He is also the founder and President of Zymo Research Corp, the leading research company in the fields of epigenetics and microbiomics. His companies made significant contributions during the COVID-19 pandemic, innovating next-generation patient sample collection and transportation devices, and supplying over 100 million COVID-19 tests globally.
