When a person is infected with influenza, the virus begins replicating in the lung. The immune system faces a serious challenge of getting antigen specific T-Cells from the lymph node to the site of infection. Because the initial infection is so small, the body must employ a number of chemical signals to properly direct the T-Cells through the huge branching network that is the lung. Drew and Soumya Banerjeer have created a spatial computer model to quantify the effect of the inflammatory signal in response to a viral infection. Their work was recently presented at the 2011 ICARIS conference in Cambridge, UK. Drew works in collaboration with Prof. Stephanie Forrest and Prof. Melanie Moses.
