Biography

Olga Kazakova received her PhD degree in Physics in 1996 from Institute of Crystallography (Russian Academy of Sciences, Moscow).

She moved to Solid State Physics Department of Chalmers University of Technology (Gothenburg, Sweden) in 1999, where she worked first as a postdoc and later on as an assistant professor in the area of nanomagnetism and nanotechnology.

Olga joined the Quantum Detection group at the NPL as a Principle Research Scientist in 2002. She leads a number of national and international projects on:

• Development of single magnetic particle detectors (nano-SQUID and nano-Hall sensors) for biological and metrological applications
• Effects of dimensionality in diluted magnetic semiconductors and oxides
• Electric scanning microscopy in graphene

She is an author of more than 80 peer-refereed publications, including Nature Nanotechnology, Physical Review, NanoLett and others.

International committees

• IEEE Magnetics Technical Committee
• IEEE Conference Executive Committee, European Liaisons
• Publication Editor, 58th Conference on Magnetism and Magnetic Materials (MMM), 2013, Denver, Colorado
