Nidal Abu-Zahra, Ph.D.

Associate Professor/Department Chair
Materials Science and Engineering

Dr. Nidal’s focus is on expanding our knowledge on contemporary issues such as cost effective harnessing of solar energy, sustainability of foam extrusion, and functionality of commodity plastics. His lab is capable of synthesizing an array of polymeric materials (thermoplastics, elastomers, and thermosets) with specific characteristics (physical, thermal, and mechanical) or functional properties. Currently, he is working on synthesizing new polymer and polymer-composite foams capable of removing heavy metal toxics from drinking water at low levels (ppb) and high cation exchange rates.
