Matthew Rabinowitz, PhD
Chief Executive Officer
Dr. Matthew Rabinowitz has had dual careers in industry and academia. He completed his B.A., M.Sc. and Ph.D. degrees at Stanford University, receiving both the Levin and Terman Awards — the highest academic honors offered respectively in engineering and physics — and a graduate fellowship to the school of engineering. While completing his dissertation, Dr. Rabinowitz co-founded an intelligent online merchandizing company, Panop.com, which later sold for $100M. Shortly after, Dr. Rabinowitz started his second company, Rosum, which developed a location technology using TV signals to augment GPS. Rosum received the World Economic Forum “100 Technology Pioneers” award when he was CTO.
In 2003, Dr. Rabinowitz’s life took a turn. A family member had a child born with a genetic disease and the child died. Dr. Rabinowitz experienced firsthand the trauma, stress, and devastation that an unexpected diagnosis of genetic disease can bring to a family and he was moved to action.
Drawing on expertise from his seemingly unrelated background, Dr. Rabinowitz embarked on a journey with the goal of ensuring that other families need not experience similar pain wrought by the inability to have a healthy child. Bringing together a team of experts in medicine, engineering, statistics, and genetics, along with his own skills in optimization, signal processing, informatics, and entrepreneurship – Natera was born.
Dr. Rabinowitz is now an authority in the field of prenatal and preconception informatics-based genetic testing. He has served as the Principal Investigator on six research grants awarded by the National Institutes of Health from which multiple publications have emerged in the leading journals of the field such as Bioinformatics, Human Reproduction, and Molecular Human Reproduction. He actively presents at medical conferences around the world, including at the annual meeting of the American College of Medical Genetics, American Society of Reproductive Medicine, and Fetal Medicine Foundation World Congress.
Dr Rabinowitz is a board member, advisor, and angel investor for multiple technology companies in the fields of biotech, communications, cleantech and healthcare. He has received the Scott Helt Memorial Award from IEEE and was selected by MIT Technology Review Magazine as one of the top 35 technology innovators under 35 in the US.
Natera’s results have been no less than remarkable. Dr. Rabinowitz and the entire Natera team share a dedicated passion to bringing the breakthrough Parental Support technology to those who need it most in their pursuit of a healthy family.

Mr. Chapman joins Natera from Genzyme, where his team was responsible for over 70 million dollars of revenue in the Northeastern United States. Mr. Chapman established the largest network of physicians in the world routinely screening Fragile X and led Genzyme’s sales initiative into population screening for Fragile X. Mr. Chapman proved to be a visionary in 2005 when he brought carrier screening of Spinal Muscular Atrophy (SMA) to the forefront of efforts at Genzyme. He played a critical role in the groundbreaking launch of SMA carrier screening in 2008 and was responsible for over 35% of the initial uptake in the United States during the first 6 months of the launch. Steve has been the direct recipient of 27 sales awards, most notably a two-time winner of the prestigious Alpine Award, which was given to one person throughout Genzyme Corporation, which has over 8,000 employees world wide.
