Justin Wark

Professor of Physics

Current Responsibilities:

I am a Professor of Physics in the sub-department of Atomic and Laser Physics, and a Tutorial Fellow in Physics at Trinity College.

I am Director of the Oxford Centre for High Energy Density Science (OxCHEDS), and hold a William Penney Fellowship awarded by AWE.

I represent the UK on the management board of the Helmholtz International Beamline for Extreme Fields (HiBEF), which is one of the end stations at the EuropeanXFEL (X-Ray Free Electron Laser) in Hamburg.

I sit on the Peer Review Panel that provides advice on the scheduling of experiments on the National Ignition Facility (NIF), which is situated in California, USA, and is the largest laser system in the world.

At the departmental level I teach the Plasma Physics course (S16) available as a short option to 3rd year students. This introductory course aims to provide a basic understanding of how we approach ways of modelling the vast majority of the visible universe using single particle, fluid, and kinetic theory treatments. A link to real-life situations, such as observable astrophysical phenomena and efforts to produce fusion energy on earth is provided.

Within Trinity College I have tutored all of the first three years including circuit theory, electromagnetism, relativity, optics, sonf electromagnetism, in the first year; thermal physics and quantum mechanics (second year), and solid state physics and atomic physics (third year).

My research interests lie in generating and understanding matter at extremes of temperatures and pressures, such as those found towards the centre of giant planets, and in the initial phases of inertial confinement fusion implosions. In our work we create matter subjected to pressures of many millions of atmospheres, and temperatures of up to many millions of degrees. The small amount of material we can make at these conditions sometimes only lasts a few trillionths of a second, during which time we must make our measurements. The experimental facilities used by members of my research group include the largest optical lasers in the world,such as the National Ignition Facility, as well as the world's first X-ray laser based at Stanford - the Linac Coherent Light Source. Our experimental efforts are backed up by sophisticated classical and quantum molecular dynamics simulations, as well as complex atomic-kinetics codes.

I currently undertake consultancy for national laboratories both in the UK and the USA, as well as UK industry. Details of my areas of expertise can be obtained from the Oxford Consultancy arm of Isis Innovation.
