Emily Leproust, PhD
Chief Executive Officer
As an early pioneer in the high-throughput synthesis and sequencing of DNA, Dr. Leproust is disrupting the process of gene synthesis to enable the exponential growth of synthetic biology applications in multiple fields including medicine, DNA data storage, agricultural biology, and industrial chemicals. In 2015, she was named one of Foreign Policy’s 100 Leading Global Thinkers for fast-tracking the building blocks of life, and Fast Company named her one of the most creative people in business for synthesizing DNA faster than ever. Prior to Twist Bioscience, she held escalating positions at Agilent Technologies where she architected the successful SureSelect product line that lowered the cost of sequencing and elucidated mechanisms responsible for dozens of Mendelian diseases. She also developed the Oligo Library Synthesis technology, where she initiated and led product and business development activities for the team. Dr. Leproust designed and developed multiple commercial synthesis platforms to streamline microarray manufacturing and fabrication. Prior to Agilent, she worked with Dr. X. Gao at the University of Houston developing DNA and RNA parallel synthesis processes on solid support, a project developed commercially by Xeotron Corporation. Dr. Leproust has published over 30 peer-reviewed papers—many on applications of synthetic DNA, and is the author of numerous patents. She earned her Ph.D. in organic chemistry from the University of Houston and her M.Sc. in industrial chemistry from the Lyon School of Industrial Chemistry in France.
