Prof. Steven Armes

Prof. Steve Armes obtained his BSc in Chemistry from the University of Bristol in 1983, which was followed by a PhD from the same institution in 1987. After a postdoctoral fellowship at Los Alamos National Laboratory in New Mexico (1987-89), he became a lecturer at Sussex University in 1989. After being promoted to Senior Lecturer, Reader and Professor in Polymer Chemistry, he moved to Sheffield in 2004 to become Professor in Polymer and Colloid Chemistry. He is currently Director of the Sheffield Polymer Centre and Farapack Polymers, a University spin-out company. He was elected to be a Fellow of the Royal Society in 2014.

Postdoctoral Research Associates

Dr. Matthew Derry

I obtained a Masters in chemistry (MChem) from the University of York in 2012, which included a 12 month industrial placement at Infineum. I then moved to the University of Sheffield, and after a brief summer research placement, started my PhD project under the supervision of Prof. Steve Armes FRS. This PhD project was fully-funded by Lubrizol and was focused on RAFT-mediated polymerisation-induced self-assembly (PISA) in industrially-relevant non-polar solvents. After receiving my PhD in 2016, I continued as a postdoctoral researcher in the Armes Group. In April 2017 I began a research project funded by the Leverhulme Trust, which is a joint venture between the Armes and Ryan-Mykhaylyk groups. I am investigating the initial micellisation behaviour of block copolymer assemblies under various conditions using sophisticated small-anglescattering techniques.

Dr. Fiona Hatton

I obtained a 1st class MChem degree in medicinal chemistry and pharmacology from the University of Liverpool in 2010. I stayed at the University of Liverpool for my PhD (2010-2014) which focused on the preparation of novel polymeric materials; hyperbranched polydendrons, with Prof. Steve Rannard. After my PhD I moved to Stockholm, Sweden to join the Division of Coating Technology, KTH Royal Institute of Technology as a postdoctoral researcher. During this time I worked primarily on cellulose modification with bio-and synthetic polymers with Assoc. Prof. Anna Carlmark and Prof. Eva Malmström. In April 2016, I returned to the UK to begin a postdoctoral research associate position with Prof. Steve Armes at the University of Sheffield, preparing functional polymer colloids. I am also currently a co-opt member of the Joint RSC/SCI Colloid Committee.


Dr. Yin Ning

I received my bachelor’s degree in polymer materials and engineering (2006-2010) and Master’s degree in materials science at South China University of Technology (2010-2013) and then achieved my PhD degree at the University of Sheffield (2013-2016) under the supervision of Prof. Steve Armes, FRS.

Now I am a research associate, working on rational synthesis of diblock copolymer nanoparticles via RAFT-mediated polymerization-induced self-assembly as well as polymer-modified inorganic nanoparticles. Then systematically investigating their incorporation into crystal hosts, aiming to unveil the mystery of biomineralization and ultimately achieve advanced hybrid materials with desired properties.
