Dr Holly Hedgeland

Professional biography

My background is in surface science with a particular interest in dynamical phenomena at surfaces. I have applied experimental techniques ranging from helium atom scattering and scanning tunnelling microscopy to synchrotron x-ray and neutron scattering to evaluate surface energy landscapes and friction. I am particularly interested in providing the novel data needed for benchmarking the latest developments in theoretical approaches such as density functional theory and molecular dynamics.

I also have an interest in Physics Education Research, stemming from MEd / MA (ODE) and practitioner studies while teaching in the secondary sector, and I am currently involved in several PER projects based at the OU.

Teaching interests

Currently on secondment, I was formerly Module Team Chair of SMT359 - Electromagnetism. I have contributed to the presentation of SS001, SXPA288, S217 and SMT359, as well as working on a wide variety of science modules as staff tutor and tutoring on SXP390.
