Dr Tomasz Puzyn is the Head of Laboratory of Environmental Chemometrics at the University of Gdansk (Poland). After obtaining his PhD in 2005 at the University of Gdansk (Poland), he spent almost two years working for the Interdisciplinary Centre for Nanotoxicity (Jackson State University, Jackson, MS, USA) and the National Laboratory for Environmental Studies in Tsukuba, Japan (post-doctoral fellowship by the Japan Society for the Promotion of Science). His main area of interest is developing computational methods for assessing the human and environmental risk of novel chemicals. His accomplishments have been widely recognized. Tomasz Puzyn is an author of many contributions devoted to POPs/POPs-like chemicals risk assessment as well as QSAR modeling. In collaboration with Prof. Jerzy Leszczynski from the Interdisciplinary Centre for Nanotoxicity, he has developed the first Nano-QSAR models. The results were recently published in Nature Nanotechnology and Small journals.
