TROWBRIDGE GROUP
Meet The Team
Aaron Trowbridge



Group Leader
Aaron completed his PhD in chemistry from the University of Cambridge in 2019 under the supervision of Prof. Matthew Gaunt developing new strategies for the selective Pd-catalyzed β-C–H activation of aliphatic amines and methodology for the multicomponent synthesis of tertiary aliphatic amines via the photocatalytic reduction of alkyl iminium ions.
He then moved to Princeton University as a postdoctoral researcher working in the laboratory of Professor David MacMillan where he developed a platform for intracellular small-molecule target ID (μMap) based upon visible-light-mediated photocatalysis in collaboration with Merck (Cambridge, MA; Kenilworth, NJ).
In 2021, Aaron returned to Cambridge as a Marie-Curie Fellow investigating the multicomponent synthesis of chiral amines using photoredox catalysis.
Currently, Aaron is a Lecturer in Organic Chemistry at the University of Manchester.
Group Members

Thomas King
PDRA
Tom joined the lab in February 2026 as a PDRA and is developing novel biomolecule labelling strategies. He completed his undergraduate and PhD studies at the University of Cambridge, under the supervision of Prof. David Spring, working on diversity-oriented synthesis and developing novel linkers for antibody-drug conjugates. He has since held PDRA roles with Prof. Sabine Flitsch, University of Manchester, working on biocatalytic peptide and protein modification, and Dr. Louise Walport, Imperial College London, working to expand the chemical diversity of mRNA-displayed peptide libraries. Outside of the lab, Tom enjoys cycling, football and watersports.

Hikaru Ishikura
PDRA
Hikaru joined the lab in February 2026 as a PDRA investigating strategies for late-stage oxygen editing. Hikaru was born in Japan and grew up in Japan, USA, and South Korea. He completed his PhD at Imperial College London with Prof. James A. Bull working on the synthesis of four-membered rings through carbocation and radical intermediates. Previously, he obtained a BSc from the Maastricht Science programme in the Netherlands and an MRes from Imperial College London. Outside of the lab, Hikaru enjoys eating and spending time with his partner and dog.

Andre Bossonnet
PhD Student
Andre joined the lab in April 2023 as a PhD student investigating late-stage skeletal editing of complex molecules via methylene extrusion. Andre is Swiss, French, and Portuguese but was born and raised in Lausanne, Switzerland. He studied chemistry during his bachelor’s and master’s degree at EPFL, Switzerland. He completed his master's thesis and a graduate internship in the laboratory of Prof. Jerome Waser at EPFL, where he worked on photocatalyzed [3+2] cycloadditions of acceptor-only cyclopropanes. Outside of the lab, Andre enjoys cooking, football, or just discovering new bars and restaurants.

Ruth Garner
PhD Student
Ruth joined the lab in September 2023 as a PhD student and is investigating red-light photoredox reactions. Ruth was born and raised in Dewsbury, West Yorkshire. She completed her MChem degree at the University of Leeds, where she did an industrial placement in synthetic chemistry at GSK in her 3rd year. She completed her final year project under the supervision of Prof. Adam Nelson, where she worked on securing covalent probes using Rhodium-catalysed annulation. Outside of the lab, Ruth enjoys climbing, crocheting, and exploring new places.

Ben Hillman
PhD Student
Ben joined the lab in January 2023 as an iCAT rotation student and has stayed in the group to complete his PhD. He is investigating photocatalytic alcohol transpositions. Ben was born in Lancashire and proceeded to complete his MChem degree at the University of Manchester with an industrial placement at AstraZeneca. He completed his final year project under Prof. Michael Greaney developing metal free aryl amine synthesis. Outside of the lab Ben enjoys going to gigs, running, and hiking.

Anson Fong
PhD Student
Anson joined the lab in October 2026 as a PhD student investigating porphyrin complexes and their applications towards red light photocatalysis. Anson is from Leeds, UK, and completed their MChem degree at the University of Sheffield. There, they worked on projects involving the total synthesis of tropane alkaloids via cycloaddition strategies under the supervision of Prof. Iain Coldham, as well as the synthesis of energetic coordination complexes under the supervision of Dr. Peter Portius. Outside of the lab, Anson enjoys arts and crafts, music and travelling.

Molly Donald
PhD Student
Molly joined the lab in October 2025, as a joint PhD student with Dr Christine Schmidt and Prof. Richard Edmondson. Her project utilises photoproximity labeling to investigate protein interactions in pre-cancerous lesions, towards ovarian cancer early detection. Molly was raised in the south of Scotland, and gained her Bsc (Hons) in Immunology and Pharmacology from the University of Strathclyde. She undertook her final-year project under Dr Natividad Gomez-Roman, assessing the effects of cholesterol-depleting drugs on astrocytes towards glioblastoma treatment. Outside of the lab, Molly enjoys going to gigs, cooking, and running.

Lucy Cannavan
PhD Student
Lucy joined the lab in September 2025 as a PhD student investigating connective isomerism as a new tool for molecular editing. She was born in Manchester and completed her Master at the University of Birmingham, where her final year project focused on the synthesis of small molecule enantioselective catalysts. Outside of the lab, Lucy enjoys running, swimming and teaching swimming.

Thomas Gogerty
PhD Student
Tom joined the lab in October 2026 as a PhD student investigating novel molecular editing strategies and connective isomerism. He was born in Wirral, Merseyside and moved to Glasgow to complete his BSc in Chemistry with Medicinal Chemistry. His final year project looked at utilising a range of deep learning strategies to design de novo peptide binders based on the target protein sequence alone. In his free time, Tom likes to play golf, go to the gym and watch football.

Lily Taylor
PhD Student
Lily is a PhD student in the Rowbotham and Trowbridge groups researching phosphorus-centred photobiocatalysis. She completed her MSc project with the Trowbridge group in P-centred photocatalysts in summer 2026. Lily was born and raised in Cheshire, where she attended school. She obtained her BSc in Chemistry from Lancaster University, and her MSc from the University of Manchester. Outside the lab, Lily enjoys embroidery and spending time in the countryside with her dog, Mabel.
