Jean Alexandre undertook his undergraduate studies and Masters at the Ecole Normale Superieure de Lyon, France, where he also obtained a teaching qualification (Agregation de Physique). He then went to the Louis Pasteur University of Strasbourg, France, where was awarded a PhD in 1998. His first postdoc was a Marie Curie position in the European network "Finite temperature phase transitions in Particle Physics", based at the National Technical University of Athens, until 2001. Jean then did a Leverhulme Trust postdoc in the Department of Physics of King's College London, after which he obtained a temporary lectureship, and then his current position.

PhD Projects

My research essentially focusses on Quantum Field Theory (QFT) as a tool for understanding different aspects of theoretical physics. I consider that QFT is beautiful, and I therefore aim for my PhD students to develop a proper understanding of its structure, and how to apply it to different areas in Particle Physics or Gravity. 

Topics I have worked on in the past few years include:

  • Quantisation of Lorentz-symmetry violating theories and Horava- Lifshitz gravity
  • Alternative mechanisms for neutrino oscillations (using non-perturbative techniques in QFT);
  • Non-Hermitian models; 

These topics are not straightforward, and so I would usually suggest a specific research project for a student to work on initially, which would enable them to develop their skills and understanding in this area. However, I expect you to build up your own intuitive understanding of Physics, and to gather research skills, so that you can become more independent and show initiative as the PhD progresses. King's has an active department and strong connections with the other London universities, and I would encourage you to get involved in the physics community that exists here.

I am currently looking for motivated students with a good mathematical background, and would encourage you to apply to King's, should you be interested.
