SUMMARIES OF CANDIDATES’ EXPERTISE
ACKERMAN, LUKE – FDA
I have developed and validated BPA methods for foods and beverages. I have used BPA methods to generate
measurements of exposure and product specific data to support regulatory decision making and risk assessments
for the US Food & Drug Administration. I have conducted reviews and commentary of the food‐BPA literature. I
have reviewed and selected methods for validation work, participated in method validation standard setting, and
participated in, and developed reference materials for inter‐laboratory proficiency testing. I have participated in
multiple aspects of collaborative methods and standards setting.
CAO, XU LIANG – HEALTH CANADA
I have been working on method development for determination of BPA and other bisphenol analogues in foods
since 2007, and applied the methods to investigate occurrence of the bisphenols in various foods and exposure
assessment, which have been summarized in numerous publications. I am also one of the experts at the 2010
WHO/FAO meeting on BPA.
GUMUSTAS, MEHMET ‐ ANKARA UNIVERSITY FACULTY OF PHARMACY
HPLC, Capillary electrophoresis, validation, chiral, electroanalytical.
LI, SIHENG – COVANCE
I’m the BPA analysis method developer in Covance Laboratories Inc. I have been working on this topic since
January 2017. I developed a LC‐MS/MS based method to determine BPA concentration in various food matrices. I
have validated the method in commercially packaged non‐alcoholic beverages, infant formula products and food
simulating solvents with satisfactory accuracy and precision.
MASTOVSKA, KATERINA ‐ COVANCE
Advance knowledge and experience in the analysis of chemical residues and contaminants and various
chromatographic and mass spectrometric techniques.
PHILLIPS, MELISSA – NIST
While not an expert in these particular areas (cannabis, BPA), I have extensive experience with method
development and also with evaluation of analytical methods with respect to SMPRs for infant formula, foods, and
dietary supplements.
SEIPELT, TOM – ABBOTT NUTRITION
Lab manager responsible for method development and routine testing of infant formula and adult nutritionals in
support of BPA packaging mitigation. Managed packaging projects to eliminate the use of BPA in infant formula
packaging. Participated in FAO/WHO stakeholder panel on BPA in 2010.
SOMAYAJULA, KASI – THE COCA‐COLA CO.
I have been working in the area of trace level quantification in various matrices using LC/MS/MS and GC/MS/MS
methods during my career.
