Dr John O'Neill

Research

My main research interest is circadian rhythms: the innate biological 24-hour clock that sustains daily cycles in behaviour and physiology in organisms as diverse as humans, plants and bacteria.

Biography

As an undergraduate I studied Biochemistry at New College, University of Oxford, and was fortunate to work in Antony Galione’s lab during my final year. I then defected to Cambridge for my PhD, working with Mick Hastings at the MRC Laboratory of Molecular Biology. Following a brief stint of post-doctoral research with Andrew Millar at the University of Edinburgh, I returned to Cambridge to pursue the many interactions between circadian timekeeping and human health. My group is based in the Cell Biology division of the MRC Laboratory of Molecular Biology. The Medical Research Council and the Wellcome Trust fund our work.
