Vice President & Program Chair
Walter Wilson
completed his PhD in chemistry in 2014 from the University of Central Florida under the mentorship of Prof. Andres Campiglia. During his time in Campiglia’s lab, his work focused on the development of new analytical extraction methods for PACs in conjunction with liquid chromatography, gas chromatography, and low temperature fluorescence spectroscopy techniques. Dr. Wilson was awarded a two-year appointment as a National Research Council post-doctoral research associate at the National Institute of Standards and Technology (NIST) under advisement of Dr. Stephen Wise and Dr. Lane Sander, where he specialized in the development of new liquid and gas chromatographic separation techniques for PACs in complex sample matrices. Currently Dr. Wilson is a research chemist at NIST, where he focuses on the development of new dietary supplements and environmental reference materials.

Carolyn Quarles Burdette
received her BS in Chemistry from Winthrop University (Rock Hill, SC) in 2007, while playing four years of D1 soccer on the Winthrop Women’s Soccer team. She then went on to earn her PhD in Analytical Chemistry from Clemson University in 2012 (Clemson, SC) under the advisement of Dr. Kenneth R. Marcus. Part of Carolyn’s work at Clemson looked at the determination of active compounds in dietary supplements by LC-glow discharge (GD)-MS techniques. This led to a relationship with NIST and help paved the way for accepting an NIH-ODS postdoc position at NIST in Feb 2013. Carolyn’s work at NIST has focused mainly on the development of methods (LC-MS/MS and LC-tandem UV-FLD-MS/MS) and materials (e.g SRMs) for the determination of fat soluble vitamins and metabolites in foods, dietary supplements, and clinical matrices. Carolyn is also involved in the administration of NIST’s HAMQAP (Health Assessment Measurements Quality Assurance Program) and is a member of JCTLM review teams. Carolyn also enjoys participating in STEM/STEAM outreach, playing soccer, hiking, cartooning, and spending time with her husband and 1yr old daughter.


Board Member (6/01/2018-5/31/2021)
Connie Africano Remoroza
is currently working at the National Institute of Standards and Technology. She has an extensive experience in the analysis and molecular characterization of carbohydrates particularly glycomics and glycoproteomics of biological fluids such as human milk and plasma as well as in the development of mass spectral libraries of these materials. She utilizes this expertise to design LC-MS methods for acquiring high quality spectra of complex mixtures of glycans and glycopeptides from the reference materials to assist the quality control and data measurement activities at NIST Standard Reference Data program, specifically the NIST Tandem Mass Library. She obtained her M.S. in Biotechnology and Ph.D. Food Biochemistry in Wageningen University, The Netherlands. Her thesis is about developing chromatograhic methods using HPSEC, HPAEC-PAD and HILIC coupled to mass spectrometry to elucidate the fine structure of pectin from sugar beet, which was funded by the European Commission 7th Framework program. She also worked as a junior scientist at Dupont, The Netherlands that involves the purification, determination of the mode of action of cellulases, xylanases and pectinases and their application to food stabilizers and bioethanol.

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.
