Professional summary

I have been working in FDA regulated industry, including both medical devices and in vitro diagnostics (IVDs), for more than 25 years. The first 11 of years of my career were focused in research, product development, and chemistry manufacturing of IVDs. The subsequent 14+ years have been focused in regulatory affairs and quality compliance for both medical devices and IVDs, including consulting for private clients as well as in service to several global CRO's as an affiliate consultant specializing in IVDs. My experience includes Class II and Class III devices for cardiovascular, nuclear medicine, general surgery and orthopedic medical devices, and IVDs for clinical chemistry, microbiology, immunology and hematology devices in a variety of formats (IHC, ELISA, IFA, lateral flow, genotyping).

I have a record of successful domestic and international regulatory submissions for medical devices and IVDs and I have managed both FDA inspections and Notified Body audits. I have assisted device manufacturers in achieving certification to ISO 13485:2003, including the design and implementation of the QMS from the ground up. I hold certification (RAC) in both United States and European Union regulatory affairs from the Regulatory Affairs Professional Society (RAPS) and I am accredited by ANSI-RAB as a lead auditor for medical device quality systems. I enjoy the challenge of aligning the research, regulatory, quality, clinical and marketing plans with the shared goal of delivering to the marketplace validated products that benefit both the patient and the clinician.
