### Keywords

T cell receptor signalling

T cell receptor diversity

Thymic selection

## Research interests

My main current interest is modelling immune responses.

Three main themes are of special interest:

[1] T cell receptor-ligand binding and T cell receptor

signalling, What determines the ability of T cells

to discriminate different antigens.

[2] Size and receptor diversity of the different T cell populations.

[3] Interactions, in vivo and in real time, between dendritic cells (that display antigens on their membrane) and T cells (that display on their membrane T cell receptors).

As a theoretical physicist I am interested in understanding particle production in the Early Universe and the validity of the semi-classical approximation to Einstein's equation.
