Emily Leproust, PhD

Chief Executive Officer

As an early pioneer in long DNA synthesis, Emily is poised to accelerate the biofactory market. She and co-founder Bill Peck share the world record for synthesizing the longest, highest quality oligo library. Emily architected the successful SureSelect product line which lowered the cost of sequencing and elucidated dozens of mendelian diseases, and she developed Agilent’s Oligo Library Synthesis technology. Emily has co-authored over 34 peer-reviewed papers—many on synthetic DNA—and has extensive marketing, management, and business development experience. Prior to Twist Bioscience, Emily was Director of Applications and Chemistry R&D—Genomics at Agilent Technologies.
