I grew up in London and got my PhD in Genetics and Microbiology from the University of Leicester in the UK. I had postdoctoral positions with Fred Sparling at the University of North Carolina Chapel Hill and with Rino Rappuoli at Sclavo Research Center (now Novartis Vaccines) in Siena, Italy. I started my faculty position here at the University of Maryland Medical School in 1991. In 2010 I chaired the organizing committee and hosted the 9th International Bordetella Symposium here in Baltimore. I am married to Tracy Irish and we have three children (Julia, Christopher and Michael).
The general interest in my laboratory includes (i) molecular and cellular mechanisms of bacterial pathogenicity, (ii) immune and inflammatory responses to bacterial infection, and (iii) cell biology of bacterial toxins. Specifically, we are studying the role of virulence factors in infection and disease caused by the bacterial pathogen Bordetella pertussis, the cause of the disease whooping cough or pertussis. We are using a mouse model of respiratory tract infection to study this host-pathogen interaction, and we are particularly interested in the role played by the secreted virulence factor pertussis toxin and its modulatory effects on the host immune response. We are also studying the retrograde transport in mammalian cells of pertussis toxin, and the intracellular trafficking pathway that this toxin utilizes to arrive at and modify its target G proteins, disrupting cell signaling events and causing toxicity. We are using various cell biology approaches to dissect this pathway and learn about the intracellular events that lead to pertussis toxin activity.
