Prof. Arwen Pearson
arwen_cui_website_pic2Arwen is a biophysicist with a background in X-ray crystallography, single crystal spectroscopy and structural enzymology and a strong interest in the development of new methods to probe biological molecular mechanisms. She obtained a BSc(hons) in Biochemistry from the University of Bath (1997) and a PhD in structural biology from the University of St Andrews (2001), working with Garry Taylor. She then did postdoctoral work in structural enzymology in the lab of Carrie Wilmot at the University of Minnesota, working on the biogenesis of the protein derived cofactor tryptophan tryptophylquinone. In 2006 she moved back to the UK to the Astbury Centre for Structural Molecular Biology at the University of Leeds as an independent research fellow, taking up a lectureship in 2011. In 2014 she moved to the University of Hamburg to join the Hamburg Centre for Ultrafast imaging as Professor of Experimental Biophysics.

Dr Briony Yorke

Dr Michael Agthe

Michael is a hybrid engineer/materials scientist and joined the Pearson group in April 2017 and together with Sam Horrell, and in collaboration with EMBL, is designing the new P14-2 endstation at PETRA III for Hadamard time-resolved crystallography. He graduated with a BSc (2008) from the Hamburg University of Technology followed by a joint MSc (2011) in materials science and engineering from Luleå University of Technology and Saarland University. During his PhD at Stockholm University Michael combined SAXS, SEM, TEM, QCM-D and video microscopy to investigate and understand the formation mechanisms of highly-ordered superstructures formed by self-assembling iron oxide nanocubes. Outside of work, his two kids keep him busy.

Dr Sam Horrell

Sam is a biochemist and graduated from the University of Leicester (2011) in Medical Biochemistry (BSc) he then moved to the University of Liverpool for a joint project with Diamond Light Source; where he worked on method development for long wavelength phasing experiments, developed the multiple structures from one crystal (MSOX) crystallography technique and studied the reaction mechanisms of EAL domain proteins. After a postdoc position at the University of Essex Sam joined the Pearson lab in April 2017 and works with Michael to help construct the P14-2 endstation.

Chris Orr
