I am an authority on the structure of glasses and other disordered materials, and an expert in the study of atomic structure by neutron diffraction.

I am employed at the ISIS Facility, which is a neutron source located in Oxfordshire in the UK.

I work as an instrument scientist on the GEM (GEneral Materials) diffractometer, and I am responsible for its scientific programme in disordered materials.

The following publication describes my main area of expertise...

Hannon, A. C., Neutron diffraction techniques for structural studies of glasses, Chapter 5 in: Modern glass characterization, Ed. M. Affatigato, Wiley, New York, 2015. See: Wiley or Amazon.
