David Stephens   ORCID iD iconorcid.org/0000-0001-5297-3240

David studied Biochemistry at Royal Holloway College, University of London and did his PhD at St. George’s Hospital Medical School (also University of London). This was followed by postdoctoral research first with Prof. George Banting in Bristol and then with Dr Rainer Pepperkok at the European Molecular Biology Laboratory in Heidelberg, Germany. David’s time there as an EMBO Long term fellow learning advanced light microscopy while working on COPII-dependent secretion. Following award of a Medical Research Council Non-Clinical Career Development Fellowship in 2001, David started the lab in Bristol. In 2005, David secured a Medical Research Council Non-Clinical Senior Fellowship He takes up his academic post in Bristol in October 2010.

David is a recognized expert in cell imaging, including publishing high-profile reviews and editing a book on cell imaging and another more recently on methods for the analysis Golgi function. Our work has led to many internationally recognized research publications, invitations to speak at prestigious meetings (e.g. Japanese Biochemical Society, Gordon conferences and EMBO workshops), and to contribute high-profile review articles (e.g. in Science and Nature). David has also served on committees of the Royal Microscopical Society and British Society for Cell Biology and was until recently a member of editorial boards for Traffic and Biology Open. He is now an Editor for Journal of Cell Science. David is also an affiliate of the BioRxiv preprint server.

David has a number of other roles to keep him busy: he is a member of BBSRC Council, Faculty Research Director for the Faculty of Life Sciences at the University of Bristol. He tweets (mostly) about Science @David_S_Bristol. David is also unit lead for the Year 4 MSci Biochemistry Programme.

Laura Vuolo (2016- ) orcid.org/0000-0002-9801-9206

Laura joined the lab following her PhD with Sebastian Pons at the  Institut de Biologia Molecular de Barcelona. Her previous work showed how ciliary adenyl cyclases are involved in Sonic Hedgehog signalling.  Her project investigates the role of the cytoplasmic dynein-2 microtubule motor in the formation and function of primary cilia.

Nikki Stevenson (2013- ) orcid.org/0000-0001-8967-7277

Nikki joined the lab in November 2013 as a postdoc following completion of her PhD studying the ability of GRK2 to modulate initiation of inflammatory responses in endothelial cells in Dan Cutler’s lab at LMCB, UCL. Nikki works on the mechanistic basis of procollagen processing and secretion as well as contributing to our projects on ciliogenesis. Nikki is also a contributor to the preLights community that highlights new preprints in biology.

Janine McCaughey (2016- ) orcid.org/0000-0001-7709-2597

Janine completed her Masters thesis in 2016 at the Leibniz University Hannover. While in our lab for one of her research projects, Janine worked on the organization of ER exit sites in relation to collagen secretion and taking advantage of our recently installed STED microscope for some super-resolution imaging. This resulted in our paper in Cell Reports. Janine is also an accomplished artist and you can see more about hat side of her life here: mccaugheyarts.jimdo.com

 

Former lab members

Juma Ward (2018) worked in the lab on rotation as part of our Wellcome Trust Programme in Dynamic Cell Biology. Juma is now working towards his PhD in Paul Martin’s lab.

Dylan Bergen (2012- 2017) was part of our Wellcome Trust 4 Year PhD Programme in Dynamic Cell biology. Dylan worked jointly between the Stephens, Hammond, and Verkade labs  on the mechanisms of extracellular matrix secretion and ciliogenesis, particularly in terms of the function of giantin in these processes. His work integrated our cell-based approaches with further zebrafish work to define the links between secretory pathway function and these critical developmental processes. He has moved on to work on genome wide association studies of osteoarthritis through a Discipline Hopping Fellowship funded by the Elizabeth Blackwell Institute for Health Research (via our Wellcome Trust Institutional Strategic Support funding).

Beth Moyse (2017) worked in the lab on rotation as part of our Wellcome Trust Programme in Dynamic Cell Biology. Rachel is now working towards her PhD in Chrissy Hammond’s lab.

Chris Johnson (2017) worked in the lab towards his MSc in Biomedical Sciences.

Ash Evans (2014- 2017) worked towards his PhD on a collaborative basis between the Stephens and Henley labs. Based almost entirely in the Henley lab, his work dissected mechanisms of membrane trafficking in neuronal cells, applying the experience of the Stephens lab in membrane and cytoskeletal dynamics to the trafficking of neuronal receptors.

Vicky Miller (2012-2015) joined the lab from Dani Ungar’s lab in York. There she worked on COG complex function at the Golgi and worked in the lab on the organization of ER export in mammalian cells using the knock sideways system and RNAi of COPII components, notably TFG.

Anna Townley (2004-2014) worked in the lab for a total of 10 years including career break to have her first child. Anna contributed to almost all projects in the lab as can be seen by her contribution to our published work.

Sylvie Hunt (2009-2014) completed her PhD using advanced imaging techniques to study the role of microtubule-based motors in membrane trafficking. Sylvie completed the last segment of her PhD working part time after the birth of her daughter.

Rachel Ambler (2014) worked in the lab on rotation as part of our Wellcome Trust Programme in Dynamic Cell Biology. Rachel is now working towards her PhD in Christoph Wuelfing’s lab in Cellular and Molecular Medicine.

David Asante (2010-2014) was a PhD student in the lab working on ciliogenesis in mammalian cells. David previously did a Masters at Oxford Brookes. He will defend his thesis this summer and has moved on to the MRC Mammalian Genetics Unit (Harwell) to work with Dominic Norris on the role of polycystin proteins in cilia.

Dawid Walas (2011) joined the lab in October for his first rotation as a PhD student on our Wellcome Trust Programme in Dynamic Cell Biology.
