Research Interests

My research is focused on signalling in lymphocytes and more specifically the role of the PI3K pathway in T-B cell interactions during an immune response. Since PI3K is known to be involved in many cellular process, we are using conditional deletion of the P110d catalytic subunit as an approach to study how PI3K activity regulates lymphocyte differentiation and functions.
