Founder & Chief Executive Officer
Barrett is Founder and CEO of Nabsys. He is passionate about the impact that advanced technology can have on the understanding of disease as well as on its diagnosis and treatment. He has raised $150 million to realize a new way of analyzing DNA that uses proprietary solid-state electronic nanodetectors to analyze very long molecules, with an initial focus on genomic structural variation.
Barrett is an adjunct professor at Brown University where he lectures on the rapidly evolving business of life sciences. He serves as a commissioner of the I-195 Redevelopment District Commission, a major land redevelopment initiative in downtown Providence, RI with a focus on life sciences and other high-technology sectors. He has received numerous awards including, in 2011, Rhode Island Innovator of the Year, and in 2018, a career achievement award from the Warren Alpert Medical School of Brown University. Barrett graduated from the highly competitive Program in Liberal Medical Education (PLME) at Brown University where he received an M.D. and an Sc.B. in Physics and won the undergraduate physics award (the Lindsay Prize) and the Galletti Prize for physics in medicine.
When he is not working, teaching, or volunteering, Barrett enjoys spending time with his wife and two young children. He also enjoys architecture and collecting antique/ancient sculpture. He has visited 60 countries, including Spain, where he has run with the Bulls in Pamplona.
