Message

At MilliporeSigma, I currently manage a team of validation project managers for sterile filtration validation services across the Americas. My work builds on earlier roles at MilliporeSigma as a VPM Manager, North America, and Validation Project Manager.

Earlier, at Toxikon Corporation, I managed and assisted a team responsible for routine and client-specific microbiological assays, handled client accounts, and created protocols, reports, and SOPs. I’m a Registered Microbiologist in pharmaceutical and medical device microbiology, with experience in validation, GMP, and microbiological testing.
