Dmitri Ossipov received his PhD in Bioorganic Chemistry from Uppsala University, Sweden. His doctoral and the following post-doctoral studies at Karolinska Institutet, Department of Molecular Biophysics and Biochemistry were devoted to the development of oligonucleotide-based therapeutics and artificial nucleases. From 2004 till 2017 he worked in the group of Polymer Chemistry (Department of Materials Chemistry, Uppsala University) where he was appointed to a position of Assistant Professor (2007) and from 2012 he is an Associated Professor in Polymer Chemistry. From spring 2018 he joined the Department of Bioscience and Nutrition at Karolinska Institutet. His research interests are in the development of biofunctional synthetic or semi-synthetic materials designed to interact with cells in vivo for chemotherapy and regenerative medicine. Current focus is on the development of single-component oligonucleotide nanomaterials that enable efficient delivery of nucleic acid therapeutics to their mRNA targets in specified tissues and cells.
