Charlotte Williams Research

Department of Chemistry University of Oxford

Dr Gregory completed her PhD in 2017 as part of the Centre for Doctoral Training in Sustainable Chemical Technologies at the University of Bath, working under the supervision of Dr Antoine Buchard. Her thesis focused on the synthesis and ring-opening polymerisation of cyclic carbonates from sugars and CO2 to form biocompatible polycarbonates for tissue-engineering scaffolds. Georgina has joined the Williams Group with research interests in the synthesis, properties and applications of bio-derived thermoplastic elastomers.

Ryan completed his PhD under the joint supervision of Prof. Andrew Smith and Prof. Polly Arnold at the Universities of St Andrews and Edinburgh. Funded by the Centre for Doctoral Training in Critical Resource Catalysis this collaborative project studied independent and combined Lewis acid-Lewis base catalysis with N-heterocyclic carbenes and rare-earth ions for enantioselective synthesis and small molecule activation. Ryan is currently researching the synthesis of polyethylene using early transition metal catalysts sponsored by SCG.

Dr. Fernando Vidal -- Fernando studied chemistry at the University of Almería (BSc. 2011) and University of Alcalá (MSc. 2012) in Spain. Having secured a Fulbright Scholarship, he pursued his PhD thesis at Colorado State University (USA) under the supervision of Prof. Eugene Y.-X. Chen working with chemo- and stereoselective metal catalysts in the polymerisation of various methacrylates. After graduating in 2017, he moved to Rutgers University-Newark where he joined the group of Prof. Frieder Jäkle as postdoctoral associate and laboratory coordinator of the PolyRUN facility. His research focused on main-group containing polymers as supramolecular materials and recyclable organocatalyst. He arrived at the University of Oxford in October 2020 as the Williams group's leading PDRA for the Oxford Martin School Future of Plastic Programme.

Dr Bradley Cowie obtained his Honours BSc degree in chemistry from McMaster University in Hamilton, Ontario, Canada. He then obtained his PhD in 2015 from McMaster University under the supervision of Prof. David J. H. Emslie, focussing on the use of late d-block complexes of Group 13 Lewis acid-containing ambiphilic ligands for small molecule activation. In November 2015, Bradley joined the research groups of Profs. Polly L. Arnold and Jason B. Love at The University of Edinburgh, UK, where he explored new avenues for the reductive functionalisation of the uranyl ion, [UVIO2]2+. In September 2020, Bradley joined the research group of Prof. Charlotte Williams at the University of Oxford, UK, and his current research focuses on the use of Cu2S nanoparticles for photoelectrochemical CO2 reduction.

Dr. Shannon Petersen began her studies at Allegheny College in Meadville, Pennsylvania, USA where she obtained a BSc in physics in 2015. She then completed a PhD in polymer science in 2020 at the University of Akron under the supervision of Prof. Matthew L. Becker. Her graduate work focused on the development of photoactive polymers that could be 3D printed into scaffolds for tissue engineering applications. Shannon joined the Williams group at the University of Oxford in February 2021, where she will be working on a collaborative project that will use machine learning to develop new, sustainable elastomers.

Thom graduated from the University of Edinburgh in 2016 (MChem). He then moved to the University of Bath for his PhD to work with Dr Antoine Buchard. At Bath, Thom investigated the synthesis of oxygenated polymers and the impact of stereochemistry on material properties. He also spent some time in Nagoya, Japan with Professor Masami Kamigaito as a JSPS summer programme fellow. Thom has joined the Williams group to develop novel methods for chemical recycling of polycarbonates and polyesters.
