Dr Thomas Ostler BSc Hons, PhD, MInstP
Lecturer in Physics and Admissions Tutor for Physics
Summary
Dr Thomas Ostler completed a PhD in computational magnetism at the University of York as part of an EU FP7 project working in the field of ultrafast spin dynamics and optical switching of magnetic materials using spin dynamics models. The research was aimed at developing theoretical models to understand the highly non-equilibriun dynamics of magnetic materials after the action of femtosecond laser pulses.
Tom joined Sheffield Hallam University as a Lecturer of Physics in March 2017 and is also the admissions tutor for the BSc Physics course.
Tom's research expertise includes the use of second principles modelling in the form of spin dynamics and micromagnetic models, as well as, using first principles electronic structure calculations to parameterise Hamiltonians in a so-called hierarchical multi-scale approach.

About
Tom began his postdoctoral positions at the University of York working jointly as a project manager for a collaborative EU FP7 project on ultrafast magnetism involving 9 universities from across Europe, and Seagate Technology. In 2015 he moved to the University of Exeter to work as a senior postdoctoral research fellow in the Group of Prof Gino Hrkac on functional materials on an EPSRC project with the University of Manchester.
In 2015 Tom was awarded a Marie Curie BeIPD COFUND project at the University of Liège hosted by the Nanomaterials group of Prof Matthieu Verstraete. The project involved using electronic structure calculations to fit second principles Hamiltonians to study the dynamics of magnetic and multiferroic materials.Tom is also a committee member for qan EU COST project (CA17123-MAGNETOFON - Ultrafast opto-magneto-electronics for non-dissipative information technology) and an elected member of the Institute of Physics Magnetism working group.
