**About the Editor**

**Elena I. Ryabchikova** graduated from Novosibirsk State University where she learned different microscopic methods and their application in various studies. She obtained her PhD degree in Anatomy, Histology and Embryology from Moscow State University (1980), and in 1982, she joined the State Research Center of Virology and Biotechnology "Vector" in Koltsovo, Novosibirsk region. She successfully used electron microscopy in studies of natural nano-objects—viruses, their structure and interaction with host cells. Her studies of biological properties and pathogenesis of Ebola and Marburg filoviruses were published in leading virological journals and were highly valued by the scientific community. She obtained a Doctor of Biological Sciences degree in 1998 for studies of filoviral pathogenesis. In 2009, Elena Ryabchikova moved to the Institute of Chemical Biology and Fundamental Medicine of the Siberian Branch of the Russian Academy of Sciences in Novosibirsk and started to work with artificial nano-objects. She applied her experience in virus investigations to understanding nanoparticle–cell interactions. A group led by Elena Ryabchikova obtained and published new data on gold, silica and palladium nanoparticles' interaction with a cell, which showed new facets in nanoparticle biology. In her publications, Elena Ryabchikova shows the need for a deep understanding of the mechanisms of interaction of nanoparticles with cells for the successful and safe development of nanobiotechnologies.
