Research Focus: Mathematical Immunology

I mathematically model immune memory regulation and memory repertoire shifts resulting from memory T-cell attrition.  More specifically, I mathematically examine how the memory CD8+ T-cell repertoire changes due to infections.  Following normal infections, the creation of new memory T-cells results in increased competition for survival signals, which in turn may lead to passive attrition of existing memory.  Furthermore, some viral infections cause massive bystander attrition of memory CD8+ T-cells early in infection; this attrition is then followed by homeostatic proliferation of surviving memory cells, along with some naive cells, to refill the memory compartment.  My work looks at how these attrition and proliferation events alter the composition of lineages within the memory CD8+ T-cell repertoire and hence affect the ability of the memory compartment to respond to particular infections should they reoccur.  I utilize a variety of applied mathematical techniques, ranging from deterministic methods to probabilistic and stochastic approaches, as required by the particular biological problems.
