A native of Jacksonville, Florida, Paul Eason completed his undergraduate and graduate studies in Materials Science and Engineering at the University of Florida. As an undergrad, Paul specialized in two fields of study; metallurgy, and ceramics engineering. Taking this hybridized knowledge base, Paul was able to apply traditional ceramic powder processing techniques to in-situ processing of intermetallic matrix composites for potential use as high-temperature structural aerospace materials. These complex alloy systems, both multiphase and reacting in nature, required establishment of new ternary and quaternary phase diagrams and employment of innovative materials characterization techniques, all of which provided the basis of Paul’s dissertation.

Following graduate school, Dr. Eason pursued a career in engineering consulting, while always remaining attached to the academic community. Providing services in materials characterization for industrial process optimization and failure analysis in both industrial and litigation based matters, Paul remained an active user of the electron microscopy facilities of the Major Analytical Instrumentation Center at the University of Florida. While maintaining his consulting practice, Paul began teaching materials engineering courses as an adjunct professor at the University of North Florida, and now serves as a tenure-track assistant professor in the Mechanical Engineering program. Concurrently, Paul was appointed to the Graduate Faculty of the Materials Science and Engineering Department at the University of Florida, where he also serves on the Distinguished Alumni Advisory Board.
