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.
