Short biography

• Valentina KRACHMALNICOFF is a CNRS researcher scientist at Institut Langevin. She obtained a PhD degree from University Paris-Sud in 2009 with a thesis on quantum atom optics experiments (PhD thesis pdf) done under the supervision of A. Aspect and C. Westbrook. In 2010, she joined the Langevin Institute (group of Prof. R. Carminati) as a postdoctoral fellow to develop a novel nanophotonic experimental setup for studying the influence of a complex environment on spontaneous emission. In 2012, she joined the Langevin Institute as a CNRS research scientist. Her research work concerns the study of the near-field interaction between fluorescent nano-emitters with nanostructured plasmonic or dielectric samples and optical transport properties in nanostructured media. She has a strong experience in fluorescence intensity and decay rate measurements of nano-objects grafted on the tip of a scanning probe microscope, and in nano-manipulation.
  In 2007 she was laureate of the prize L’Oréal France – UNESCO “For Women in Science”.
  In 2017, she was awarded the CNRS Bronze Medal. The CNRS Bronze Medal recognizes a researcher’s first work, which makes that person a specialist with talent in a particular field.
