**About the Editors**

**Piotr Cysewski** was born in Poland in 1960. He received his MD and Ph.D. in Chemistry from Nicolaus Copernicus University, Torun, Poland in 1984 and 1988, respectively. In 2013, he was awarded the title of Professor of Chemistry. Currently, he is the General Chair of Physical Chemistry Department, Collegium Medicum, Nicolaus Copernicus University, ul. Kurpinskiego 5, 85-950 ´ Bydgoszcz, Poland. He has published more than 200 scientific papers in the field of computational chemistry applied to biochemically interesting systems. His current research covers such topics as cocrystallization of active pharmaceutical ingredients, structural and energetic diversities of modified double-stranded DNA, including epigenetic modifications and modelling of the structure and properties of deep eutectics.
