Lois Ann Beaver. Upon graduation in 1963 with a BS in Chemistry and Mathematics, from Rosary Hill College, Lois Ann Healy (now Beaver) joined the U.S. Food and Drug Administration in Buffalo, NY as an analytical chemist where she developed a deep interest in separation science that continues to this day. At FDA headquarters she held several positions including overseeing the trace analytical work of FDA field labs, mass spectrometry projects and official method development. An idea conceived while working in the lab led to a dozen patents on a system and apparatus for real-time multi-dimensional chromatography, and the founding of an instrument company called Varex Corp. that functioned for 10 years in Rockville, MD. The last period of her multi-decade FDA career involved international activities in the Office of the Commissioner where she served as liaison with international organizations such as WHO (World Health Organization), OECD, (Office of Economic Cooperation and Development) and APEC, (Asia Pacific Economic Cooperation), served on numerous US delegations, and was a member of the FDA Pharmaceutical Quality Council that conceived and developed quality by design. Lois also led international projects on anti-counterfeiting of medical products and good manufacturing practices in emerging countries and established a pharmaceutical information center in Cairo. She is a member of the Washington Chromatography Discussion Group, the ACS Chemical Society of Washington, and the Chromatography Forum of the Delaware Valley and is on the organizing committees of HPLC 2018 and PREP 2017.
