    Dr Maria Nowicka (Department of Pathology and Cell Biology, Columbia University, US) Differential impact of self and environmental antigens on the ontogeny and maintenance of CD4+ T cell memory
    Laboratory mice not exposed to overt infections nevertheless develop populations of circulating memory phenotype (MP) CD4+ T cells, presumably in response to environmental, commensal or self-antigens. The relative importance and timing of the forces that generate these populations remain unclear. We combine mathematical models with data from studies tracking the generation of CD4+ MP T cell subsets in mice of different ages, housed in facilities that differ in their `dirtiness'. We infer that both central and effector CD4+ MP T cell populations derive directly from naive CD4 T cells, and are heterogeneous in their rates of turnover. We also infer that early exposure to self and environmental antigens establishes persistent memory populations at levels determined largely, but not exclusively, by the dirtiness of the environment. After the first few weeks of life, however, these populations are continuously supplemented by new memory cells at rates that appear to be independent of environment, likely in response to self or ubiquitous commensal antigens.

Current and recent visitors

  • Joe Gillard and Tom Laws
  • Mario Castro works on mathematical models of systems where fluctuations are relevant (cellular and receptor immunology) and on pattern formation in spatially extended systems (from tumor cell modeling to cauliflower morphogenesis or nano-structuring). The figure shows comparisons of different mathematical models with real experiments.

Applications for research leading to a PhD are welcome. Please apply here, naming a potential project and supervisor. Sample projects are as follows:
  • Analysis of high-throughput genomic data applied to diseases such as cancer
    Arief Gusnanto, Charles Taylor, Jeanine Houwing-Duistermaat
    Statistical modelling of copy number alteration in cancer: using statistical methodology to discover patterns within the genomic copy number alteration profiles in cancer patients and how the pattern can be utilised for improved prediction of cancer survival and patients' clinical characteristics.
    Genetic association in complex diseases and cancer: a collaboration with research groups in the School of Medicine to perform fine mapping around a previously identified location to identify genetic variants that are associated with cancer.
  • Mathematical immunology
    Grant Lythe and Carmen Molina-París
    Development of stochastic mathematical and computational models of the immune system in health and disease, of intra-cellular signalling to understand cell fate, and development of diffusive motion models of cell-cell interactions and receptor-ligand interactions.
  • Modelling biodiversity and ecosystems
    Sandro Azaele
    In this project you will be developing mathematical and computational tools for modeling spatial and temporal patterns in ecosystems, understanding their principal drivers across different scales, at population and community level. This will also help developing methodologies for upscaling biodiversity information from fine-scale sampling.
  • Modelling evolution on molecular and macroscopic scales
    Mauro Mobilia
    Inspired by recent results in biology, and also in behavioural sciences, we will combine notions of non-linear dynamics and evolutionary game together with the theory of stochastic processes and numerical simulations to investigate how noise and mobility influences the formation of coherent patterns.
  • Modelling of biomolecules
    Oliver Harlen and Daniel Read, in collaboration with the Astbury Centre
    Simulating the motions of large biomolecules such molecular motors and also soft colloidal particles, entities that are large enough to be beyond the scope of atomistic simulations (that model the motion of individual atoms), but small enough to be affected by thermal fluctuations (Brownian motion).
