About

Martin Long is a Lecturer in the Theoretical Physics group at Birmingham University.

Martin has published over 50 research papers in scientific journals, including reviews on frustrated antiferromagnetism and the Hubbard model.  He is heavily involved in postgraduate education, having graduated about 15 PhD students at Birmingham and is currently jointly responsible for the Midland Physics Alliance Graduate School.

Qualifications

  • PhD in Physics, 1984
  • MA in Mathematics, 1981
  • BA in Mathematics, 1980

Biography

Martin Long qualified with a BA in Mathematics from the University of Cambridge in 1980.  He went on to study for a PhD in Theoretical Condensed Matter Physics at London in 1984.  After postdoctoral study at Harwell Laboratory, the Rutherford Appleton Laboratory and Oxford University, he took a Physics Lectureship at Bath University for four years before transferring to Birmingham University in 1993 where he has stayed ever since.  He researches into magnetism and superconductivity using a broad spectrum of analytical and numerical techniques, usually being closely involved with experiments.  One major theme of his postgraduate teaching has been trying to make experiments more accessible to young theorists, through both courses and PhD supervision.
