Neal Armstrong is a Regents Professor of Chemistry/Biochemistry & Optical Sciences, and Associate Vice-President in Research, Discovery and Innovation at the University of Arizona.  

His research is focused on developing the new measurement science required to understand and control, at nanometer length scales, the chemical, physical and electrical properties of interfaces between electrical contacts and new active layer materials for solar cells, new photoactive nano crystalline materials for light-to-fuel formation, and new active layers for light emission.  While reasonably efficient energy conversion and light emission platforms are becoming available, they are expensive and not scalable.  The challenges in creating massively scalable energy conversion technologies often lies in understanding and controlling composition, structure and energetics of the interfaces between electrical contacts and active layers.
