Jonathan P. Mathews

Professor of Energy and Mineral Engineering

Research focuses on the structure and behavior of coal and other disordered carbonaceous materials, including coal-derived carbons, chars, biochar, kerogen, soot, and related carbon materials. The work combines molecular and atomistic modeling with HRTEM and image analysis, pore-structure characterization, and studies of CO2, CH4, pyrolysis, combustion, carbon-material formation, and alternative uses of coal.
