Robert O’Toole

Rob is from Milnrow, Greater Manchester, and completed his MChem the University of York in 2021. In his third year he completed a summer internship with Dr Luke Wilkinson, focused on computational (DFT) modelling of molybdenum paddlewheel complexes. He later completed his fourth-year masters project with Dr Alyssa Avestro, investigating how through space conjugation of NDI triangle analogues affect their charge-storage properties. He then moved to the University of Reading, where he continued his studies under the supervision of Dr James Cooper, investigating how rotaxanes behave in the phospholipid bilayer, with a specific focus on the interplay between rotaxane dynamics and anion transport processes. He was awarded the Oxford University press poster prize at MASC 2025, just after completing his PhD studies. In early 2026 he joined the Williams group as an EPSRC funded postdoctoral research fellow, where he will be constructing hemi-indigo photoswitches for potential uses as anticancer therapeutics. Outside the lab, Rob enjoys hiking, video games and board gaming, and is an avid LEGO builder.
Zhihao Ling
Ling is from Shanghai, China. He completed his BSc Chemistry at the University of Liverpool in 2023. Their BSc dissertation was about the sustainability in organic synthesis in the teaching lab under the supervision of Dr Gina Washbourn and Dr Catherine Cropper. Then, he completed his MSc Chemistry by Research in 2024 under the supervision of Dr Matthias Baud, and the project was to synthesize and assess possible small molecule chaperones for multiple sulfatase deficiency. He then took a short placement under the supervision of Dr George Williams to research a functional organic material based on indigo-type photoswitches. His PhD is focusing on synthesis of Hemi-indigo and novel types of photoswitches under the supervision of Dr George Williams. Outside of the lab Ling likes photography and travel.

Alex Buchanan

Alex is from Thame, Oxfordshire and completed his integrated MChem at the University of Southampton in 2024. In his 4th year, he completed a research project in Professor Gill Reid’s group focusing on synthesising phosphinate ester functionalised macrocycles for group 13 metal fluoride chelation. Alex joined the Williams research group in September 2024, with his research focusing on photoswitches for incorporation into mechanically interlocked polymers. Outside of the lab, his hobbies include a love for (amateur) baking, climbing, football and reading.
Becky Kerridge
Becky is from Ledbury, Herefordshire, and completed her Integrated MSc in Chemistry at the University of Birmingham in 2024. In her third year, she undertook an industrial placement in the medicinal chemistry department at Sygnature Discovery, a Contract Research Organisation (CRO) based in Nottingham. During her fourth year at Birmingham, she completed a research project in Dr. Timothy Barendt’s group, focusing on synthesizing Perylene Diimide (PDI) based macrocycles. Becky started her PhD in the Williams group in September 2024, with her research focusing on photoswitchable antimicrobials for wound infections. Her hobbies outside of the lab include hockey, climbing and painting.

Anne Aarvik

Anne Aarvik completed her BSc in Biological Chemistry at the University of Stavanger (UiS) in 2022, working on pancreatic cancer metabolism for her final project. She went on to do a MSc in Molecular Medicine at the Norwegian University of Science and Technology (NTNU) finishing her degree in May 2024. She spent the last year of her MSc researching organoids as a potential model for studying pancreatic cancer under supervisors Professor Duan Chen and Chun-Mei Zhao, PhD. In September 2024 she moved from Norway to England to do an integrated PhD in biomedical science at the University of Southampton. She is currently working on a research project focusing on the development of hydrogel structures to improve pancreatic cancer chemotherapy under supervisors Dr George Williams, Dr Nicole Prior, and Dr Nick Evans.
Matthew Russell
Matt is from Purley, Croydon and completed his integrated master’s in chemistry at the University of Southampton in 2025. In his 3rd year, he completed a summer Internship in Dr Matthias Baud’s lab, where he investigated molecular chaperones that reinstated function to p53 with the mutated Y220C codon. He followed up on this research in the Baud group as part of his Master’s, synthesising indole derivatives. Matt then started his PhD in 2025 with the Williams group, currently focusing on the synthesis and integration of hexaarylbiimidazoles (HABIs) into functional materials. Outside of the lab, Matt is currently on Team GB for Roundnet and is an avid Arsenal fan.

Mariko Cook
Mariko Cook completed her MChem at the University of Southampton with her final project under the supervision of Prof. Eugen Stulz and Dr Chloe Howells. Her research explored the potential of ionic liquids as sustainable storage and reaction media for nucleoside phosphoramidites. Alongside her studies, Mariko joined the team at SouthWestSensor Ltd.. There she worked as a Research Assistant and later Graduate Chemist in the development of microfluidic sensor devices for the continuous monitoring of phosphate, nitrate, and ammonium levels in water. In 2025, she started in the Williams group for her PhD. Her research focuses on developing hydrogel-based chemosensors for the detection of metal ion contamination in seawater.
