Sylvie Roke

from Wikipedia, the free encyclopedia

Sylvie Roke (* 1977 ) is a Dutch physicist and chemist specializing in biophotonics . Since 2007 she has been director of the Max Planck Institute for Metals Research. Roke is particularly interested in the surface of water and what happens on the surface. Her main research interests relate to the structure of water and the water molecules present.

Career

Roke graduated from Utrecht in 2000 with a degree in chemistry and experimental physics. She continued her studies at the Faculty of Chemistry at the University of Leiden and received her PhD in nonlinear interface optics in 2004. She then worked as a postdoctoral fellow at the FOM Institute for Plasma Physics in Nieuwegein , Rijnhuizen, and then won the Humboldt Research Fellowship at the University of Heidelberg . Since 2007 she has been leading the metal research team at the Max Planck Institute for Metals Research .

research

  • Roke studies the surface structure of water. In doing so, she developed a measuring method to understand processes such as the transport of oxygen in the blood.
  • The scientist analyzes how electrolytes react with water. She observes how the dipole orientation, the charge transfer and the distortions of the hydrogen bonds change.
  • Roke improved the non-linear microscope and was able to record living mammalian cells. With the help of these images, she was able to assign these cells to specific organelles and processes. This method also enables the scientist to analyze how special drugs work.
  • Researcher Roke deals with hydrophobicity , which is understood as a rejection process, and discusses this on a molecular level. She found that zero charged droplets are created by a cleaning process that has no effect on the movement of the oil droplets.

Publications (selection)

Scopus has 115 publications in which Roke is involved. These were cited in 1563 publications. Since the beginning of her publication activity (2000) her Hirsch Index 2020 was 32. In 2019 she published 20 publications, which were cited 503 times.
