Prof. Ivan Vorobyev earned his Ph.D. in Dept. of Cell Biology and Histology, Moscow State University. Since that he held research positions at A.N. Belozersky Institute for Physico-Chemical Biology, Moscow State University and for many years continued research on the centrosome structure and dynamics of microtubules. He described in detail centriole fine structure (1980) and relationship between centriole cycle and cell cycle (1982). Together with D. Zorov he discovered in 1983 mitochondria fragmentation. He earned Doctorate of Sciences degree in Cytology in 1989. In 1997 described free microtubules as ubiquitous part of cytoskeleton in animal cells. He supervised more than 15 graduate students and was advisor for 10 Ph.D. thesis. In 1988-2015 he was PI on 14 grants from Russian Basic Science Foundation. In 1998-2012 he was Head of the Laboratory of Functional Morphology of Hemoblastoses, Hematology Research Center (Moscow). Since 1995 he was appointed as Professor at the Dept. of Cell Biology and Histology (Moscow State University) teaching courses on Cell Biology, Cytoskeleton, Digital and Confocal Microscopy, Flow Cytometry.
