Professor of Physical Chemistry, Department of Chemical Engineering, Imperial College London

Professor Sergei Kazarian is Professor of Physical Chemistry in the Department of Chemical Engineering at Imperial College London, a post he has held since 2006. His principal research interests are molecular spectroscopy of polymeric materials and supercritical fluids processing. His overall strategy is to combine physical chemical studies with chemical engineering research and applications.

Professor Kazarian is interested in studying intermolecular interactions in polymers and supercritical fluids, using them to engineer new products and processes. He develops and applies in situ spectroscopic methods to study supercritical fluid-polymer interactions, plasticisation of polymeric materials, supercritical fluid dyeing, drying, extraction and impregnation. In recent years his research interests have broadened to include preparation of polymer/drug formulations, supercritical fluids enhanced processing, rheology, separations using supercritical fluids and ionic liquids.

In most recent years his research has focused on the development and applications of advanced spectroscopic imaging methods. These include FTIR spectroscopic imaging (specifically attenuated total reflection (ATR) imaging in both macro and micro modes), confocal Raman microscopy and tip-enhanced Raman scattering. FTIR spectroscopic imaging brings to light a whole new range of possibilities in complex materials, forensics, pharmaceutical and biomedical research.

Multidisciplinary collaborations with colleagues from universities, industry and government institutions play an important role in his research, focusing on solving problems with implications for health, the environment and security as well as those of significant industrial interest.
