Personal profile
Biography
I did my degree and PhD in Biochemistry at King’s College London, where I first worked on Xenopus. I went on to post-doc fellowships working on gene regulation at CRUK and the Developmental Biology Research Centre, both in London. From there I moved to Portsmouth setting up an independent lab working on gene regulation in Xenopus and in 2006 led the inception of the European Xenopus Resource Centre funded by the Wellcome Trust. Having Portsmouth as a hub for the latest developmental biology research makes it a very exciting place for me to study and, after doing my five year turn as head of school, I am currently enjoying working hands on alongside my team in the lab.
Alongside my Xenopus work I enjoy collaborating with the Marine Biologists in Portsmouth to support their use of the latest molecular genetics technologies in fascinating applied research projects.

Research Interests
My team researches gene regulation in the early development of the Xenopus (clawed frog) embryo. This includes transcription factor regulation (Brzostowski et al, 2000, Cazanove et al 2008) and epigenetic mechanisms (Steer et al 2003, Abu-Daya et al, 2005). Currently we are performing a systematic analysis of the function and control of the variant histones in early development in collaboration with Dr Fiona Myers. Half of MJG’s time is dedicated to running the European Xenopus Resource Centre (EXRC), in this context developing improved techniques for working with Xenopus (Love et al 2012) and enhancing frog welfare (Abu-Daya et al 2012).
