Dr. Gilliam founded Chemetry, originally as a research division within Calera Corporation, in 2008. Through Chemetry, Dr. Gilliam seeks to redefine how commodity chemicals are made through taking a new look at an old industry. Dr. Gilliam obtained his Ph.D. from the University of Toronto in Materials Science and Engineering. On his work in catalysis and electrochemistry, Dr. Gilliam has 10 peer-reviewed publications and has presented his work at multiple international conferences. He is an inventor on 26 U.S. Patents and an additional 60 foreign patents pertaining to Calera’s and Chemetry’s work.

Mr. Snyder is responsible for developing and executing corporate strategy to commercialize Chemetry technologies. He is a global chemicals and plastics industry executive with over 30 years experience capturing operational improvements and building cultural alignment across acquired and geographically diverse businesses. Most recently, Mr. Snyder served as Vice President of Strategy for Axiall Corporation, leading corporate planning, strategy, and M&A activity, implementing the divestiture of underperforming assets. Previously, he served as Vice President, Chlorovinyls and Aromatics. Prior to Axiall, Mr. Snyder led a range of businesses in the U.S. and Europe at Nova Chemicals. Mr. Snyder began his career at Dow Chemical before joining DuPont Dow Elastomers, leading the global business development organization for the joint venture. Mr. Snyder holds a Bachelor of Science degree in Chemical Engineering from the University of Virginia and a Master’s of Business Administration from the Wharton School of the University of Pennsylvania.

Mr. Garcia joined the team in 2010 and leads the company’s finance and administration organization.

Dr. McWaid has thirty years of experience in product design, systems development, and engineering management. He spent four years at the National Institute of Standard and Technology’s Precision Engineering Division, first as an NRC Post-doctoral fellowship recipient, and then as a staff research engineer. Dr. McWaid has developed automated reactors, advanced metrology instruments and analytical systems. He has 11 issued patents related to metrology, and materials development and characterization. Dr. McWaid obtained his Ph.D. from the University of California at Santa Barbara in Mechanical Engineering.

Dr. Weiss leads engineering and economic modeling activities. Before joining the team, Dr. Weiss was Vice President of Research for Gas Reaction Technologies. At GRT, he led research teams developing bromine-based processes for the conversion of natural gas to liquids, natural gas to olefins, and propylene to propylene oxide. Previously, Dr. Weiss was a consultant for the Boston Consulting Group, working in new product development and post-merger integration. He is an inventor on 19 U.S. Patents. Dr. Weiss earned a B.S.E. from Princeton University and a Ph.D. in Chemical Engineering from the University of California, Santa Barbara.

Dr. Bansal joined the team in 2010 and heads the Intellectual Property department where she manages all patent and trademark related activities for the company.
