Peter Kelleher is a graduate of Trinity College Dublin. He trained in internal medicine in Dublin and clinical immunology in London and Oxford. His PhD thesis on dendritic cell function in retroviral infection was conducted under the supervision of Professor Stella Knight at the APRG Unit, Imperial College London. Dr Kelleher research interests are in the immunology of HIV-1 infection and primary antibody deficiency and the application of novel immunological technologies to the diagnosis of patients with infectious diseases and immune based disorders. Current research interests include studies evaluating the contribution of HIV-1 specific antibody responses in acquistion of HIV-1 and control of acute HIV infection  in high risk men who have sex with men. We also focus on defects in B cell memory may underlie the risks of invasive bacterial disease and impaired bacterial vaccine responses in HIV-1 infection.  The laboratory is the investigation of novel immune defect in patients with primary antibody deficiency. The immunology laboratory is also involved in multi-centre clincal and laboratory based studies European and UK in patient with HIV-1 infection, CVID,complement deficiencies and ventilator associated pneumonia.


Dr Kelleher holds honorary consultant positions with the HIV & Sexual Directorate at the Chelsea & Westminster NHS Foundation Trust, the Department of Respiratory Medicine, Royal Brompton & Harefield NHS Trust and the Department of Infection & Immunity at Imperial College Healthcare NHS Trust.  His NHS duties include provision of clinics for patients with primary immune deficiencies and HIV-1 infection and the direction of diagnostic Immunology Laboratories at Imperial College Healthcare NHS Trust.
