The U.S. National Committee (USNC) to the IEC is pleased to announce the three individuals selected to attend the 2025 IEC Young Professionals (YP) Workshop in New Delhi, India: Cassie Williams of Ohmium International, Inc., Aaron Petronico of HP Inc., and Mark Ruedinger of Rockwell Automation.
The three recipients, chosen by the USNC YP selection panel, will be sponsored to participate in the September 15-19, 2025, workshop held in conjunction with the 89th IEC General Meeting. They will represent the U.S. at a dedicated workshop alongside recipients from other nations, where they will learn more about the IEC, standardization strategies, and conformity assessment. They will also have the opportunity to attend technical meetings where standards are developed; observe a meeting of the IEC Standardization Management Board and the Conformity Assessment Board; benefit from the guidance of a mentor; visit a local industry; and more. The recipients will receive financial support for their travel and up to six nights of accommodation.
Cassie Williams is a seasoned compliance professional and engineering manager with over 12 years of experience in engineering, project management, and conformity assessment, including a background in military service. Currently serving as a fellow in product compliance at Ohmium International, she has successfully led the certification of hydrogen generator systems across multiple regulatory frameworks, including ISO 22734, Hydrogen generators using water electrolysis — Industrial, commercial, and residential applications, UL 2264A, Outline of Investigation for Water Electrolysis Type Hydrogen Generators, and CE Mark requirements. Acting as both lead compliance engineer and project manager, she has worked closely with international agencies including UL, Electrical Testing Laboratories, TUV, and Bureau Veritas to ensure product safety, quality, and regulatory alignment. Her expertise covers product compliance, agency communication, risk mitigation, root cause analysis, and process development. Williams actively contributes to the development and refinement of technical standards through participation in industry standards committees, further advancing best practices in emerging technologies. She has developed test plans, managed vendor specifications, and overseen inspections to meet the highest standards of engineering excellence.
Dr. Aaron Petronico is a leader in battery safety, regulatory compliance, and design. He has seven years of industry experience focused on lithium-ion batteries and emerging energy storage technologies, and his Ph.D. research was focused on battery technologies. During his tenure at HP Inc., Petronico has been responsible for understanding industry standards including IEC 62133, Safety Testing for Lithium-Ion Batteries, and IEC 62619, Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for secondary lithium cells and batteries, for use in industrial applications and emerging regulations, including EU Lot 3 and EU End User Replaceable Battery. He advises management and technical leaders on how best to deliver high quality products and experiences for customers while meeting or exceeding regulations and applying relevant standards. When new regulations and voluntary requirements are in the comment period, Petronico champions leveraging existing standards verses non-peer reviewed methodologies.
Mark Ruedinger has served for the past 11 years as a full-time hardware engineer, demonstrating growing leadership in the area of standards conformity. His work encompasses working with IEC standards and country-specific standards, and harmonization between the two. As a qualification engineer, he has created and overseen test systems to prove electromagnetic (e.g., IEC 61000, Electromagnetic Compatibility), climatic, and related immunity/withstand for PLC products. As a compliance engineer, he coordinated the technical and documentation strategy for adhering to IEC standards related to functional safety (IEC 61508, Electronic Functional Safety), explosive atmospheres (IECEx 60079-7, Explosive atmospheres), and cybersecurity (IEC 62443, Security for industrial automation and control systems). He also serves as a compliance researcher, analyzing the potential future impact of new technologies and potential upcoming updates to standards, particularly related to functional safety developments.
