Meredith Sellers, Ph.D., P.E., CEng, is a principal in Exponent's Metallurgical & Corrosion Engineering practice with over 15 years of experience in materials performance, asset integrity, process reliability, and failure analysis. She specializes in damage mechanisms affecting process piping and vessels, integrity management, industrial process facility investigations, and expert witness litigation and arbitration support across oil and gas, chemical processing, and consumer products industries.

Dr. Sellers provides process-driven failure analysis and integrity management services, helping clients understand how system design, materials selection, and operating conditions interact to support reliability and safety across complex industrial operations. Her work often focuses on the interplay between operating conditions and the performance of systems, piping, equipment, and products. As a Licensed Professional Chemical Engineer, Chartered Chemical Engineer, and NACE Certified Corrosion Technician, she combines practical knowledge of real-world processes with a rigorous understanding of industry standards (API, NACE, ASME) to deliver actionable insights that help clients prevent failures and improve operations.

Dr. Sellers is a long-standing member of the Society of Women Engineers (SWE) and the Association for Women in Science (AWIS), and she is an active participant in community science, technology, engineering, and mathematics outreach activities. She currently serves as the Co-Chair of the Equal Representation for Expert Witnesses (ERE) initiative.

Oil & Gas Facility Failure Analysis and Integrity Management

Dr. Sellers has investigated failures and performance issues at refineries, offshore platforms, and liquefied natural gas (LNG) facilities. She focuses on damage mechanisms (e.g., corrosion, stress corrosion cracking, hydrogen embrittlement) affecting process piping and vessels from a chemical engineering perspective, including the evaluation of operating temperatures, pressures, and process fluids. She has led root-cause investigations of units and equipment such as reactors, heaters, heat exchangers, separators, pressure vessels, pumps, turbines, gaskets, valves, and analyzers/indicators/gauges.

She has also assisted operators and owners in assessing integrity management programs, including inspection practices, damage mechanism reviews, and fitness-for-service evaluations. Her work regularly requires analysis of process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), and inspection isometrics. She draws on her Certified Risk Based Inspection Professional (API 580) and NACE Certified Corrosion Technician credentials, as well as her extensive experience with federal and international code requirements and industry standards pertinent to process piping and natural gas utilities.

Industrial Process Facility Investigations

Dr. Sellers has extensive experience evaluating systems, piping, and equipment in industrial process facilities including those used for pharmaceuticals and polymers manufacturing, medical device sterilization, fertilizer and food production and storage, and biowaste processing, among others. She has investigated failures at large- and small-scale facilities, including those resulting in loss of containment events. She also assists clients who are designing and updating facilities with material selection questions and challenges.

Consumer Product and Medical Device Materials Issues

Using her familiarity with materials characterization techniques, Dr. Sellers assists consumer products and medical device clients in investigating potential issues identified during design, manufacturing, testing, and use. She routinely consults on materials selection and performance, contamination analyses, process development and validation, extractable and leachable assessments, and product reliability evaluations and recalls.

Semiconductor Manufacturing and Thin-Film Characterization

Dr. Sellers leverages her thin-film synthesis and characterization background to help troubleshoot issues with integrated circuit fabrication equipment and semiconductor manufacturing processes. She has investigated the impacts of process upsets on tool integrity as well as failures of furnaces, deposition chambers, implanters, vacuum pumps, and etching systems. She has experience reviewing process documentation for historical and modern semiconductor manufacturing operations to inform toxicological and environmental assessments.

Expert Witness Support and Testifying Experience

Dr. Sellers has served as an expert witness in U.S.-based litigation and international arbitration matters involving materials failures, oil and gas projects, infrastructure and equipment, and industrial process facilities. She has been designated as an expert in state and district court in the U.S., as well as arbitrations pursuant to International Chamber of Commerce (ICC), UNCITRAL, London Court of International Arbitration (LCIA), and AIDA Reinsurance and Insurance Arbitration Society (ARIAS) rules.

Professional Background

Before joining Exponent, Dr. Sellers was a postdoctoral researcher at the U.S. Army Engineer Research and Development Center — Construction Engineering Research Laboratory (ERDC-CERL), where she developed and evaluated carbon nanotube, graphene, and metal oxide-based supercapacitors. Her doctoral thesis research at the University of Illinois at Urbana — Champaign (UIUC) focused on the chemical vapor and atomic layer deposition (CVD/ALD) of titanium dioxide and the optimization of its electrical properties for photocatalysis and supported metal catalysis. This entailed the extensive use of materials characterization techniques such as X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS).

Before entering graduate school, Dr. Sellers held research appointments in the Micro-Total-Analytical Systems and Entry Control & Contraband Detection Technologies organizations at Sandia National Laboratories and in the Department of Chemistry at University College London.
