John M. Baldwin, Ph.D.

Dr. Baldwin's expertise includes polymer science and technology, specializing in the synthesis, compounding, degradation (chemical/physical), and testing of elastomer, plastic, adhesive, and foam based systems.

Prior to joining Exponent, Dr. Baldwin worked in the Research Laboratory of Ford Motor Company, where he became internationally recognized for his research on the topics of tire aging, tire test development, tire service life prediction, and the use of nitrogen as a tire inflation media. Before joining Ford Research, Dr. Baldwin worked in the Advanced Manufacturing Technology Department where he researched and implemented high volume, automated adhesive, sealer, and structural foam dispensing processes along with automated in-process quality tests. Based on his professional and academic background, Dr. Baldwin was placed on a major tire recall root cause analysis team, where he was responsible for developing, coordinating, and implementing the chemical and physical testing of thousands of new and recalled tires.

Dr. Baldwin worked for the 3M Company prior to joining Ford. While working in the 3M Automotive Division, he developed and serviced a line of 2-part structural epoxy adhesives that were sold to automotive manufacturers and the aftermarket. Dr. Baldwin, as a member of 3M Occupational Health and Environmental Specialties Division, was responsible for the material research and development, as well as the process engineering, of the blown microfiber non-woven filter media used in maintenance-free respirators.

Dr. Baldwin holds an appointment as an Adjunct Associate Professor of Chemistry at Oakland University in Rochester, Michigan, where he teaches classes in polymer synthesis and polymer characterization.
