Dr. Igor F. Perepichka is a senior research associate in the chemistry department of Durham University (UK), working with Professor Martin Bryce on self-organised nanostructures as part of the European Science Foundation programme. He was educated at Donetstsk Polytechnic and completed his PhD in organic chemistry in the Institute of Physical Organic and Coal Chemistry of the National Academy of Sciences of the Ukraine, where he started his career as an engineer and was later promoted to senior research scientist in 1989. Dr. Perepichka has been a Humboldt Fellow at Wuerzburg University, a visiting scientist at CNRS in Angers and an invited professor at Angers University.Professor Dmitrii F. Perepichkais an assistant professor in the department of chemistry at McGill University in Montreal (Canada). He was educated at Donetsk State University (Ukraine) and completed his PhD in organic chemistry at the Ukraine National Academy of Science in the Ukraine in 1999. He spent two years as a postdoctoral researcher with Professor Martin Bryce and then from 2001 to 2003 he worked in the lab of Professor Fred Wudl at UCLA, working on a number of projects including the synthesis of conjugated polymers and the functionalisation of carbon nanotubes. His main research interests are materials chemistry, organic synthesis, molecular electronics, surface and nanoscience.

"A well-referenced introduction to the broad field of thiophene-based materials and their applications. ... A worthy addition to the collection of both those looking to enter the field and the seasoned researcher of conjugated polymers." (Angewandte Chemie International Edition, 2010)
