I am the lab head and Principal Investigator of the Davis lab. I am also a Wellcome Trust Senior Fellow, a Research Fellow of Jesus College and I hold the University of Oxford Chair of Cell Biology. I have been working in the Department of Biochemistry here in Oxford since 2007, where I am also the director of the Micron advanced imaging facility. To view my profile on ORCiD please click here
I have always held a keen interest in the influence of RNA localisation and how this influences development. In the past my lab has focussed on how mRNA transport and localised translation impacted on Drosophila embryonic axis specification. In recent years we have expanded our interest to include the same basic molecular processes to the Drosophila nervous system, in particular the brain and neuromuscular junction.
In order to achieve our scientific aims we use a wide range of scientific techniques, including advanced imaging techniques as well as an array of genetic and biochemistry-based methods.
Keywords: mRNA localization, Drosophila nervous system development, translational regulation, Drosophila oogenesis, pattern formation, embryonic development, neuromuscular junction, live cell imaging, super-resolution microscopy, electron microscopy, RNA biochemistry, RNA bioinformatics.

During my PhD, I was amongst the earliest pioneers of the study the mechanism of mRNA localisation  and during my postdoc, I was amongst the first to establish the use of GFP in living Drosophila tissue. My own lab developed new FISH methods to show that mRNA localisation was unrelated to the nuclear position of transcription . We also established an in vivo assay for mRNA localisation and used it to show directly for the first time that the molecular motor, Dynein transports mRNA in the embryo . During my first senior fellowship funding period (2002-2007), we applied such methods to elucidating the mechanism of grk (TGF-alpha) mRNA localisation in the oocyte  and mapped the signals responsible for grk mRNA localisation . We have also shown that mRNA anchoring in the blastoderm embryo occurs through Dynien acting as static anchor . During my second senior fellowship funding period (2007-2012), we showed that Dynein is also responsible for the movement of mRNAs from the nurse cells into the oocyte . We have demonstrated that our unconventional model of static anchoring by Dynein is operating in the case of gurken mRNA anchoring in the oocyte . We have also shown a new role for the Hippo-Wartz-Salvador pathway in somatic cells, influencing mRNA localisation in the germ line , a study that built on our earlier work showing a role for the ERM protein merlin in the same process . Most recently, we have pioneered new imaging approaches to test the association of trans-acting factors with motor proteins  and developed novel image analysis approaches with wide application to the study of mRNA and chromosome dynamics . In 2011 we published our work elucidating the polarity and dynamics of microtubules in the oocyte, a long standing contentious issue . We also applied super resolution imaging to imaging actin at the immunological synapse in collaboration with Dan Davis .
