- Researching the molecular mechanisms underlying sleep and circadian rhythm regulation
- Group Leader
- BBSRC David Phillips Fellow
I am a BBSRC David Phillips Fellow at the Sleep and Circadian Neuroscience Institute within the Nuffield Department of Clinical Neuroscience. My group researches the molecular mechanisms that regulate circadian clock entrainment.
All organisms show 24h rhythms in their physiology and behaviour, orchestrated by a circadian clock that coordinates internal time with the external world. Our research aims to understand the molecular mechanisms by which the circadian clock picks up cues from the external environment and is set to the right time. Some of our ongoing projects are listed below.
1) The role of Salt Inducible Kinases in regulating sleep and circadian rhythms:
2) The interaction of sleep and circadian signalling pathways:
3) The effect of light and other environmental inputs on the molecular clockwork:
About me: I read for a DPhil on the mechanisms of RNA interference at Brasenose college, Oxford. I subsequently joined the Sleep and Circadian Neuroscience Institute as a Roche Post-Doctoral Fellow in to work on the circadian clock and have stayed in the unit to become a group leader. I was awarded the L’Oreal Women in Science Fellowship in 2015 and I am the founder of a spin-out company, Circadian Therapeutics, that translates some of our research into the clinical arena. I am also a mother of two and am a passionate advocate for women in STEM careers.
