Short Professional Biography

Dr. Bilyeu earned both his B.S. in chemistry (1995) and Ph.D. in Materials Science & Engineering (2003) from the University of North Texas. His Ph.D. research involved thermal phase transitions and mechanical properties in polymers, which led to later work in materials and methods for water and wastewater treatment. He served as a Visiting Assistant Professor at Southeastern Louisiana University (2004-05) and Texas Woman's University (2005-06), before coming to Xavier as an Assistant Professor in the Fall of 2006. In addition to teaching and research, he serves as the Director of the Dual Degree Engineering Program and the Executive Director of the Louisiana Engineering Advancement Program for K-12 outreach. He has co-authored 8 book chapters, 28 peer-reviewed journal articles, 33 conference presentation preprints, and has 2 US patents.


Research Interest

Dr. Bilyeu's current work includes natural and synthetic material for adsorption of metals from water and wastewater and the optimization of engineered polymers and composites. The water/wastewater work involves evaluating the effectiveness, kinetics, and mechanism of metal ion adsorption onto biomass and synthetic polymers and electrochemical processes using a variety of analytical instruments (Inductively Coupled Plasma Atomic Emission Spectroscopy, Scanning Electron Microscopy with Energy Dispersive X-ray Analysis, Ion Selective Electrodes, and others). The engineering work involves thermal analysis and mechanical characterization of thermophysical properties and phase transitions to optimize the composition and processing of materials and composites to applications using Differential Scanning Calorimetry, Dynamic Mechanical Analysis, Thermogravimetric Analysis, and Scanning Electron Microscopy.
