Dr. Alexandra Rogacheva

Projects
High-Q metamaterials

Short CV
Dr. Alexandra Rogacheva received MSc (summa cum laude, 1998) and PhD (2004) from M.V. Lomonosov Moscow State University (Russia). In year 2005 she was visiting Metamaterials Group at the University of Southampton's School of Physics and Astronomy as a research assistant. Since 2006 she has been working for EXPRO Wireless Well Solutions (UK) providing analytical support for research and operational activities. In May 2010 Alexandra re-joined Metamaterials Group as a visiting researcher (now at the University of Southampton's Optoelectronics Research Centre). Her current research interests lie in the fields of metamaterials and toroidal electrodynamics.
