Gabriel has seven years of industry experience in technology transfer and manufacturing of drug products. He started working with Bristol Myers Squibb (BMS) as a process engineering contractor and then as a Senior Process and Product Scientist. As the technical site leader for technology transfer and validation of tablets for HCV treatment, he developed expertise in scale-up, identifying critical process parameters, establishing process robustness monitoring plan, performing manufacturing risk assessment, performing statistical and capability analysis, design of experiments (DOE), experimental design work, validations reports, and quality investigations. As a product champion, he was the global technical leader for the manufacturing process of tablets for HCV treatment and oversaw the transfer internationally. He was also site technical lead for the transfer of validation of bilayer-coated tablets with two different release profiles for two different drugs. He performed and led successful scale-up, improvements, and validation, supporting manufacturing product filling and regulatory inspections.
