**Olga Lavrik**

Prof. Olga Lavrik received her PhD in 1972 from M.M. Shemyakin and Y.A. Ovchinnikov Institute of Bioorganic Chemistry, Moscow, Russia. She is the head of the Laboratory of Bioorganic Chemistry of Enzymes of the Institute of Chemical Biology and Fundamental Medicine (Novosibirsk), Professor in the Department of Molecular Biology of Novosibirsk State University, and the head of the Department of Physical–Chemical Biology and Biotechnology, Altai State University, Barnaul, Russia. The current research interest of Dr. O. Lavrik and her laboratory includes the investigation of supramolecular machines of base excision repair (BER) and nucleotide excision repair (NER) and their contributions to human health and longevity. The mechanism of poly(ADP-ribosyl)ation catalyzed with PARP1, PARP2, and PARP3 and an understanding of the role of poly(ADP-ribose) in the regulation of DNA protein and protein–protein interactions in DNA repair is the main research field of interest of Dr. Olga Lavrik. The effective inhibitors of PARP1/PARP2 and tyrosyl-DNA phosphodiesterase 1 were identified with a high potential as anticancer drugs. She is the author or co-author of more than 400 scientific papers and reviews. She is a full member of the Russian Academy of Science.
