Professor Chris Sammon

Professor of Polymer Science


Summary

I am a chemist with an interest in the design, characterisation and manufacture of polymer systems for a range of applications mainly at the interface with biology. I aspire to develop a good understanding of hydrophilic matrices in the presence of water; how their chemical nature, external stimuli and additives influence interactions and structures. 

I am also interested in the distribution and mobility of small molecules in polymeric systems and I have conducted studies on synthetic and natural biopolymers, hydrogels, pharmaceutical systems, cellular materials, saline separation systems, paints, plastisols and cellulose ethers. I am also interested in the development and synthesis of amphiphilic hydrogels for regenerative medical applications. I have a strong interest in the application of vibrational spectroscopy and imaging techniques to facilitate an understanding of structure property relationships in the systems outlined.

Other activities

I have been an elected member of the EPSRC College since 2007. I am a Fellow of the Royal Society of Chemistry and have Chartered Chemist (CChem) status. I am an elected member of the RSC Biomaterials Chemistry Special Interest Group (2011-present), the Infrared and Raman Discussion Group committee (2012-present) and the RSC Molecular Spectroscopy Group (2014-present). I was elected Chair of the Recent Appointees in Polymer Science (RAPS) network (2003-2008) and was an elected member of the RSC MagroGroup UK committee (2006-2014). I regularly perform as an external examiner in PhD vivas. Since 2005 I have performed this role on 16 occasions at institutions including University of Oxford, University of Durham, Warwick University, University of Nottingham and University of Manchester.
