The Howard group combines simple, predictive mathematical modelling with long-lasting experimental collaborations, to dissect biological mechanisms too complex to unravel by experiments alone.
The group is currently focusing on three main areas;
- How cells remember past events, through epigenetic memory systems
- How cells control their size, through sizer mechanisms
- Spatiotemporal protein dynamics
Previous high-profile work in the group has revealed a reaction-diffusion mechanism for mid-cell division in E. coli, surface area-based dynamics of a cell sizer molecule in fission yeast, an arithmetic division mechanism for metabolic timing and an all-or-nothing epigenetic switching mechanism, with epigenetic gene silencing directly antagonised by transcription.

Two postdoctoral positions are available in Martin’s group to work on theoretical approaches to epigenetics, transcriptional control and liquid-liquid phase separation. The deadline for applications is 14 October 2019
Enquiries to join the group from interested postgraduate and postdoctoral scientists are always welcomed.
