Sunny founded A2-Ai in January of 2023, a venture dedicated to technology-driven clinical pharmacology and pharmacometrics using modern efficiency tools and automation. Previously, she spent time at Sanofi-Aventis, Amgen, and Pfizer. She co-founded her previous business (Ann Arbor Pharmacometrics Group, “A2PG”) in 2007 after Pfizer's departure from its site in Ann Arbor, Michigan. With A2PG, she worked on hundreds of regulatory submissions for clients throughout its highly successful 15 years of PK/PD consulting, until her company was acquired. As a unique leader who is well-versed in both scientific and business aspects of the drug industry, she frequently helps clients proactively find alternative development pathways.
