John Thompson

Principal Application Scientist

John Thompson rejoined Nabsys in June 2023 as a principal applications scientist after having helped progress the technology while working there from 2011-2014 in a variety of R&D roles. In the intervening years, he developed a greater appreciation of the critical need for understanding structural variations while in senior research positions at other biotechs. He developed assays for diagnosing rare Mendelian diseases (Claritas), somatic variation in cancer (PGDx, now LabCorp), and AAV-based gene therapy for rare diseases (Homology Medicines).

Prior to these positions, he led molecular biology and pharmacogenomic teams at Pfizer and developed novel applications for single-molecule sequencing at Helicos, including directly sequencing a 700,000-year-old DNA from what passed as horses at the time. That work was recounted in *Nature* and is one of his >100 peer-reviewed publications. Prior to joining industry, he was a Research Assistant Professor of Molecular Biology at Brown University, researching lambda site-specific DNA recombination. This work followed his PhD from the University of California, Berkeley and BS from Yale University, both in chemistry.
