Regulatory Compliance Expert Quality and Compliance

Dr. Steiner has over 35 years working in the pharmaceutical and medical device industry. He entered industry as a Ph.D. chemist working in Research & Development and then Process Development and Process Engineering. With this diverse technical background Dr. Steiner transitioned in Quality Management (Quality Assurance/Quality Control) in roles with increasing responsibility. During this time, he also earned a certification in Regulatory Affairs from San Diego State University and became an ASQ Certified Quality Auditor (CQA). The last 12+ years working full time at pharmaceutical/bio-pharmaceutical and medical device companies Dr. Steiner was department head for Quality Assurance and in some positions also for Quality Control.

Warning Letters

Now Dr. Steiner uses his extensive technical background (including materials science: adhesives & composites) and knowledge in building Quality Management Systems (QMS), maintaining regulatory compliance, process validation, regulatory compliance audits (primarily FDA & EU). He is able to lead diverse groups through Root Cause Analysis, Failure Modes and Effects Analysis (FMEA), Quality by Design (QbD), the FDA (or ICH) QSRs (Quality System Regulations) and responding to FDA Warning Letters.


American Society for Quality Certified Quality Auditor (ASQ CQA)
Dr. Steiner has been a certified quality auditor for over 17 years performing hundreds of quality (regulatory compliance & ISO) audits over four (4) continents in a variety of industries (pharmaceuticals, medical devices, chemicals, aerospace, miscellaneous commercial manufacturing and software.

Expert Witness
Dr. Steiner’s technical expertise (process development/engineering, adhesives, composites) and knowledge of regulatory compliance (FDA) has enabled him to be recognized by the US Federal Courts as an Expert. He is also recognized by many state courts as an Expert in these same areas.

Quality and Compliance Presentations and Recent Publications
Dr. Steiner has advised numerous companies about building compliant systems and performing and addressing GAP Analysis for existing quality quality systems. Most of these companies were involved in medical devices, pharmaceuticals/bio-pharmaceuticals or combination devices all of which require compliance to FDA and/or EU Regulations. Some of these companies were seeking compliance and or testing to ISO standards such as ISO 9001, an international standard that specifies requirements for a Quality Management System (QMS).
The two attached presentations provide an example of Dr. Steiner’s passion in these areas.

Adhesive Failure & Epoxy Failure

Many of Dr. Steiner’s expert consulting or expert witness engagements concern actual or suspected failure in adhesive and epoxy bonds in aerospace, medical device, pharmaceuticals, packaging, industrial, and construction applications. In fiber composites, the issues typically revolve around suspected cracks/micro-cracks, which might result from improper fabrication/processing or stresses experienced during use and especially cyclic stresses.
