Biography

Dr Daniel Eakins is an experimental scientist working at the interface of "extreme" materials science, shock physics and dynamic measurement science. He conducts research on the ultrafast behaviour of materials under extreme loading conditions, using a combination of gas-guns and high-power lasers to study key physical processes from their lattice-level origins to the bulk scale. 

Daniel's work encompasses the dynamic strength and failure of both metals and ceramics, with emphasis on heterogeneous systems. He is an expert in the shock response of porous/cellular materials, having focused on dynamic energy absorption in additive manufactured lattices, and tuning of shock-induced reactions in granular mixtures.

Since arriving in the UK, Daniel has helped pioneer the use of advanced X-ray imaging methods to provide new details on the behaviour of materials under shock compression. He received his PhD in Materials Science and Engineering from the Georgia Institute of Technology in 2007, after which he was awarded a Director’s Postdoctoral Fellowship at Los Alamos National Laboratory. In 2010 he joined Imperial College London as a lecturer to help establish the Institute of Shock Physics, serving as its Deputy Director.

Since 2017, he has held an Associate Professorship and Magnesium Fellowship within the Solid Mechanics and Materials Engineering Group at the University of Oxford.
