Professor Joseph Keddie
Joseph (Joe) Keddie is Professor of Soft Matter Physics within the Soft Matter Physics Group at the University of Surrey.
After graduating with a PhD from Cornell University (USA) in 1993, Joe spent two years as a post-doctoral researcher in the Polymer & Colloids Group at the Cavendish Laboratory, University of Cambridge followed by one year as an Oppenheimer Fellow there . At Cambridge, he used spectroscopic ellipsometry and environmental-SEM to study polymer thin films and colloids. In 1995 Joe moved to the University of Surrey as a Foundation Fund lecturer. Throughout his time at Surrey, he has carried out research on soft matter, with special interest in polymer colloids. In recognition of his contributions to the understanding of polymer dynamics of polymers in thin films and colloidal dispersions, he was awarded the 2001 Paterson Medal and Prize by the Institute of Physics and named a Fellow. His research group has won two Roon Awards from the Federation of Societies for Coatings Technology for papers presented at their Annual Meeting. In 2006 he was inducted into the Phi Beta Kappa honour society by his alma mater, Alfred University. He was selected to deliver the 2017 Thomas Graham Lecture by the RSC/SCI Joint Colloids Group.
A co-author of >150 journal articles and book chapters, he also holds two US patents and has recently submitted two international patent applications. He has written - along with his co-author, Alex Routh, at the University of Cambridge - a book entitled Fundamentals of Latex Film Formation: Processes and Properties, which was published in 2010 by Springer. His current h-index is 41 (according to Google Scholar).

My research team explores relationships between the structure and properties of soft matter systems. We also investigate fundamental processes in polymer colloids, including drying, ordering, coalescence, and water transport.
We make use of a numerous non-invasive techniques to characterise soft matter. We frequently employ NMR profiling, atomic force microscopy, UV-Vis-NIR ellipsometry (with a brand-new instrument), and thermomechanical analysis. We have recently used national facilities for small-angle neutron scattering and ion beam analysis (Rutherford backscattering and elastic recoil detection). Recently, we have been investigating the suitability of super-resolution optical microscopy to soft matter systems.
We study a variety of variety of soft matter systems. Recent examples are:
- Polymorphs of amino acid crystals
- Physically and chemically crosslinked gelatin
- 2-D materials (MoS2) in polymers
- Carbon nanotubes and graphene oxide in polymers
- Surfactant-free polymer colloids
We develop soft matter for applications. Recent examples are:
- Switchable pressure-sensitive adhesives
- Self-stratifying coatings
- Plasmonic and photonic materials made using Au nanoparticles
- Fibronectin-nanopatterned substrates for cell growth
- Radiation detectors from semiconducting polymers and small organic molecules
Our research is inter-disciplinary, and so we collaborate regularly with chemists, who synthesise molecules and particles, and with engineers with expertise in applications. Our work is appreciated and supported by industry.

I developed and co-ordinate a module on Properties of Matter (PHY1039), which introduces first-year students to classical thermodynamics and solid state physics.
I am the Co-ordinator of the Year One practical laboratory on "Properties of Matter" and "Atoms and Quanta."
I developed and co-ordinate a module on Soft Matter and Biological Physics (PHY3040). I deliver lectures to final-year undergraduates on molecular interactions, phase equilibria, dynamics of liquid, colloids, and polymer physics.
I am the Senior Tutor for the Professional Training work placement programme for the Department of Physics. Typically, about 40 students spend a year working in industry each year. I manage their assessment, and I support students preparing for a placement year.
- Our paper in Physical Review Letters on "Dynamic Stratification in Drying Films of Colloidal Mixtures," has an Altmetric score of 689 (in the 99th percentile for publications of a similar age). We report our discovery a mechanism for stratification in which small colloidal particles accumulate on a layer of larger particles.
- Our experimental and computational work to test a model of stratification in colloidal films, entitled "Stratification in binary colloidal polymer films: experiment and simulations", is freely available to read in the RSC journal, Soft Matter. We gain a deeper understanding of the parameters that result in stratification.
- We have reported a method to assembly plasmonic nanoparticles in a periodic structure templated by colloids in a publication in ACS Nano entitled "Fast Assembly of Gold Nanoparticles in Large-Area 2D Nanogrids Using a One-Step, Near-Infrared Radiation-Assisted Evaporation Process." It is freely available to read.
- I have co-authored a book entitled Fundamentals of Latex Film Formation: Processes and Properties, published by Springer in 2010.
