Felix Hofmann

Associate Professor of Engineering Science

TEL: 01865 283446


Felix completed both his M.Eng. and D.Phil. in the Department of Engineering Science, University of Oxford. He was a student at Trinity College.

On completing his D.Phil. under the supervision of Professor Alexander Korsunsky, he spent six months as a PhD+ scholar. In January 2012 he moved to MIT to work under the direction of Prof. Keith Nelson. He returned to Oxford as a senior research fellow in January 2013. He is also a college lecturer in Trinity College.


His tutorial teaching at Trinity covers engineering mathematics, providing essential tools that underpin the more applied aspects of the Engineering Science course. Tutorial teaching happens in groups of 2 or 3 students and is an excellent opportunity to discuss the material in detail and address challenging questions as they arise.

In the Department of Engineering Science, Felix gives lecture courses on solid mechanics and materials, and organises laboratory sessions.

Research Interests

Atomic scale defects are central to the mechanical, physical and failure properties of almost all structural alloys. These defects may, for example, be introduced by mechanical deformation, chemical changes or irradiation.

Felix is interested in characterising these defects and understanding the dramatic changes to material behaviour they may cause. To probe their structure and properties he uses a wide range of experimental techniques, concentrating in particular on X-ray diffraction. The short wavelength of X-rays, similar to the distance between atoms in many metals, makes them ideal for probing crystal lattice defects.

These experiments are combined with models that cover a wide range of length scales, from considering single atoms to macroscopic components. Two main topics he is currently working on are armour materials for future fusion reactors, and focussed ion beam machining for the manufacture of micro-mechanical systems.
