physical and chemical characterization and material/product quality and stability determination.
Reviewed, conducted, and evaluated equivalency & superiority studies of analytical methods,
preformed method transfer of analytical methods, Conducted atypical, troubleshooting and out of
specification investigations. Performed routine and non-routine physical and chemical tests on raw
materials, Performed statistical data analysis. Performed unknown compound identification.
Supported product registration, changes, regulatory filings, CAPA commitments and regulatory
questions. Ensured GMP/GLP compliance of data, notebooks, memos, and reports. Created &
revised test procedures, standard operating procedures (SOP) and final reports. Trained
departmental personnel on instrumentation, SOP’s and procedures. Supervised & trained personnel.
Served as department safety officer.
• Evaluated analytical laboratory quality of external manufactures to meet quality and
productions standards reducing the Sub-Saharan Africa Raltegravir’s price to $1.85 per day.
• Reduced lab expenditures by 60% by developing and implementing a lab inventory for 1,200
different HPLC and GC columns
• Evaluated European Medicines Agency (EMA) compliance guideline for Residues of Metal
Catalysts Specification Limits and the Unites Stated Pharmacopeia (USP) monographs
<232> and <233> for elemental impurities to ensure company compliance.
• Responsible for all aspect of laboratory: Inspections, training on safety procedures, and
ensuring adherence to corporate safety SOPs and policies for every departmental personnel
• Oversaw the analytical technology transfer to of over 100 methods to 20 manufacturing and
quality facilities, internal and external to the company.
• Examined more than 15 product lines and10 vendors for potential outsourcing of the
manufacture of Merck’s active pharmaceutical ingredients, Examined and compared their
product quality to Merck’s standards to ensure quality and cost.

investigations including processing problems. Assisted regulatory group with responses to worldwide
regulatory agency questions and requests.
• Eliminated redundant testing of approximately 50 laboratory tests by developing vendor
qualification methodologies to accept material based upon vendor Certificate of Analysis.
• Developed, validated an alternate method for the HPLC assay of parahydroxybenzoate
preservatives & their sodium salts, method is being reviewed for adoption by the EP.
• Reviewed, conducted, and evaluated over 200 equivalency and superiority studies of
analytical methods to determine compliance to published guidelines such as International
Conference on Harmonization (ICH) USP and FDA
• Oversaw the stability analytical method improvement project: evaluated analytical methods
for all company drug products, drug substances and registered intermediates, rectifying
deficiencies in method validation and generating data necessary to bring methods in
compliance.

support of product registrations. Performed cleaning method validations to support manufacturing
sites. Assisted manufacturing sites worldwide with Out of Specification and Atypical laboratory
investigations including processing problems. Assisted regulatory group with responses to worldwide
regulatory agency questions and requests. Developed and validated analytical methods and tests to
determine product quality.
• Reduced redundant laboratory testing of compendial methods by 1/3 by reviewing, and
evaluating equivalency and superiority studies of analytical methods while keeping
compliance to worldwide compendial guidelines
• Developed a photographic guide for TIMOPTIC XE ocumeter customer complaints, reducing
the time and effort necessary to examine customer returned products for defects or
tampering.
