Alexander received a degree in Electronics Engineering from the Department of Crystal Physics, Faculty of Electronic Materials and Devices, Moscow Institute of Steel and Alloys, and a PhD in Physics and Mathematics from the A V Shubnikov Institute of Crystallography, Russian Academy of Sciences.

Alexander has over 30 years' experience in solid-state physics, nanotechnology and quantum metrology. In his early days in Moscow, he studied charge transport in semiconducting and fast-ion conducting bicrystals. Later, he spent over 10 years at Chalmers University of Technology in Gothenburg, Sweden, investigating Josephson devices in high-T_c superconductors (HTS). In particular, he worked on the development of submicron technology for the HTS materials and studied a range of mesoscopic effects in ultrasmall HTS Josephson junctions before joining NPL in February 2002.

Since joining NPL, Alexander has led a number of projects concerning quantum metrology; magnetic and superconducting macroscopic quantum systems; single particle detection; terahertz photon counting; scanning probe microscopy; and graphene.

In 2007, he was appointed Visiting Professor and in 2013 Professor of Physics at Royal Holloway, University of London. He teaches a course 'Frontiers of Metrology' to third year undergraduates and supervises a number of PhD students.

Alexander was made an NPL Fellow in Solid State Quantum Technologies in March 2016
