Dr. Mathew’s research investigates the use of waste products in construction materials including reclaimed waste-to-energy aggregates, foamed glass aggregates, and flat panel display glass. His primary focus in on the use of these materials in cementitious products including cast in place concrete, masonry blocks, and precast applications. Dr. Mathews is a licensed professional engineer with a background in structural design and materials. He currently severs on the ASTM C09 committee for concrete and concrete aggregates (2017 – present) and the ASCE SEI Sustainability Disaster Resilience Committee (2021 – present).
Before joining Penn State Harrisburg in August 2015, Dr. Mathews was a research assistant at the University of South Carolina. Dr. Mathews also worked at Ferrell Engineering, Inc. (2008 – 2011) designing steel connections for high rise buildings.
- Reuse of waste products in construction materials
