Dr Tim Craggs
Group Leader

Tim obtained his MSci in Chemistry from the University of Cambridge in 2002, and completed his PhD there in 2007. He has been a lecturer in Chemical Biology at the University of Sheffield since 2016.

Ben Ambrose
PhD Student

Ben is a 3rd year PhD student working on developing single molecule techniques for measuring short-range interactions. He enjoys personifying inanimate objects by adding googly eyes to them, and completed his MChem degree at the University of Sheffield.

Dylan George
PhD Student

Dylan is a 2nd year PhD student co-supervised by Tim Craggs and Ashley Cadby in the Department of Physics. He is studying the development of a high throughput single-molecule FRET system. In his spare time he likes watching and playing rugby .

Alice Rhind-Tutt
PhD Student

Alice is a 1st year PhD student using SAXS and smFRET techniques to investigate the RnaseH2 enzyme and it’s role in mutations linked to Aicardi-Goutiere Syndrome. She graduated from the University of Liverpool with an MPhys degree in 2019.

Anna van den Boom
Visiting Student

Anna is working with Craggs Lab for 5 months as part of her undergraduate degree in engineering physics at Fontys University of Applied Sciences, The Netherlands. She is developing an eTCSPC set up for measuring lifetimes and anisotropy of fluorophores. In her spare time she enjoys archery.

Becky Coxon
MChem Student

Becky is in her final year of undergrad at the University of Sheffield. Her masters project is focused on protein purification and gold nanoparticle SAXS, and in her spare time she loves going for walks with her dog, Ollie.

Callum Johnston
MChem Student

Callum is a final year undergraduate studying chemistry at the University of  Sheffield. His project is based on smFRET of biomolecules and his pastimes include playing bass.
