Dr Joseph Bell-Tyrer

PDRA (Sept 2023-, funded by EPSRC)

Joey graduated from the University of Auckland in 2018 with an BSc(Hons) in Chemistry. He then joined Professor Margaret Brimble's lab at Auckland to conduct a PhD on the cycloaddition of vinyl azides with enolates, and the rearrangement pathways of the resulting triazole intermediates. In Sep 2023, he moved to the UK to start a postdoctoral position in the Cresswell lab, working in the area of photoredox catalysis for primary amine C-H functionalisation. Joey enjoys fishing, cooking, playing guitar, music production, and chess. He is also a keen sportsman (rugby and cricket), and his latest ambition is to complete a triathlon.

Hannah Askey

4th Year Ph.D. (started Oct 2020, funded by University of Bath and AstraZeneca)

Hannah graduated from the University of Leeds in 2020 with an MChem degree in Medicinal Chemistry. She carried out her Master's project in the Nelson group, where she expanded the substrate scope of a photoredox Minisci-type reaction for use in the elaboration of drug fragments. In her third year, Hannah undertook an industrial placement at AstraZeneca in Macclesfield, during which she was responsible for the process development of a Suzuki reaction that was later run on the plant. Her PhD research currently centres on the photocatalytic C-H functionalisation of primary amines. When not in the lab, Hannah enjoys tending to her jungle of houseplants and trying out new vegan recipes.

Divyaakshar Parmar

3rd Year Ph.D. (started Oct 2021, funded by EPSRC/GSK iCASE)

Divyaakshar graduated with a Masters degree in Chemistry from KU Leuven, which included two synthetic organic research projects with Prof. Dr. Erik Van der Eycken. The first focused on ruthenium-catalysed C–H functionalisation for peptide modification, and the second on photoredox-catalysed alkylation of imines with nucleophilic radicals. His research in the Cresswell group is initially focused on visible light photoredox catalysis.

Darren Richards

2nd Year Ph.D. (started Oct 2022, funded by Centre for Sustainable and Circular Technologies and BASF)

Darren graduated from the University of Bath in 2022 with a 1st class MChem degree in Chemistry. During his undergraduate degree, he carried out a research project in the Hill group focusing on the synthesis and reactivity of +1 oxidation state aluminium compounds. In October 2022, he started his PhD in the Cresswell lab to work in the area of photoredox catalysis for primary amine C-H functionalisation. In his spare time, Darren likes to play the guitar to old-school rock and heavy metal alongside going to the gym.

Marcus Shanley

2nd Year Ph.D. (started Oct 2022, funded by University of Bath, Royal Society, and Janssen)

Marcus graduated from the University of Bath in 2022 with a first-class Master’s in Chemistry. During his third year, he completed a 12-month placement working in Early Chemical Development at AstraZeneca, Macclesfield, applying visual kinetic analyses to establish process understanding and improve the sustainability of precious metal-catalyzed transformations. During his final year project, Marcus studied in the Cresswell Group, investigating the photocatalytic hydroaminoalkylation of vinyl sulfones. Marcus’ PhD research is focused on applying photochemistry and flow chemistry as enabling techniques for modular azacycle construction. Outside of the lab, Marcus is extremely active in Scouting. He holds many roles, including a Queen’s scout, cub scout leader, scout leader, tomahawk throwing instructor, and air rifle instructor!

2nd Year Ph.D. (started Oct 2022, funded by University of Bath, Royal Society, and UCB)

Emma graduated from the University of Bath in 2022 with a MSci in Natural Sciences, including an industrial placement year in medicinal chemistry at Roche. Her masters project in the Bull group involved investigating a new methodology for the carboxylation of aromatic building blocks. Her PhD project focuses on the development of a new approach to azacycle synthesis using photoredox. When not in the lab, Emma can be found giving historical tours of Bath, hiking up a mountain, or getting lost in a new country.
