I am a clinician scientist. My undergraduate degree was from Trinity College Dublin and I then trained in Dublin before undertaking specialty training in Infectious Diseases at the Mayo Clinic, USA. During this period I developed my interests in macrophage immunology and in the regulation of apoptosis.
I joined the University of Sheffield in 1998 and developed my research with a particular focus on how macrophage apoptosis regulates innate immune responses with particular emphasis on pneumococcal infection. In 2005 I received a Wellcome Senior Clinical fellowship.
I am currently a Professor of Infectious Diseases and a consultant in the department of Communicable Diseases at the Royal Hallamshire Hospital with an interest in HIV medicine and infections in immunocompromised hosts.
My research interests stem from understanding how macrophages contribute to the innate immune response against bacteria and viruses. We have developed a variety of tissue culture models as well as several in vivo models using the pneumococcus as a probe. We have applied these to a variety of other infections including Staphylococcus aureus, Neisseria meningitidis and Pseudomonas aeruginosa as well as HIV-1 and Influenza A virus infection. In particular we are investigating how the host response can utilize induction of apoptosis to enhance microbial killing and regulation of the inflammatory response and how this can be manipulated by specific pathogens.
Our current work focuses on understanding how microbial killing in organelles such as the phagolysosome sensitizes the macrophage to initiate a programme of apoptosis which involves downregualtion of the anti-apoptotic Bcl-2 family member Mcl-1 and ultimately leads to a mitochondrial pathway of apoptosis. We investigate how macrophage phenotype or specific pathogens can alter this host response.
We are also interested in how clinical diseases may alter susceptibility by modulating macrophage host responses. As part of the MRC-ABPI COPD consortium we are investigating how COPD modifies macrophage responses to respiratory bacteria. Our group also are examining how HIV-1 modifies macrophage responses to pneumococci in the lung.
Our work interdigitates closely with that of colleagues in our department. Investigation of apoptosis link closely with Prof Moira Whyte, investigation of myeloid cell biology and the regulation of pulmonary inflammation and pulmonary disease with Prof Ian Sabroe and Prof Moira Whyte, and studies on in vivo models of inflammation with Dr Helen Marriott. Our proteomic studies are carried out in collaboration with Prof Phillip Wright (Chemical and Process Engineering).
I am also research lead for the South Yorkshire and North Trent HIV network and work closely with Dr Christine Bowman in co-ordinating local studies and our participation in national MRC sponsored clinical trials. These focus on the efficacy and complications associated with antiretroviral therapy.
My teaching focuses on the pathogenesis and clinical features of HIV and other infectious diseases.
