 I've worked on East Coast fever for 14 years initially in in Illry. I then moved away from Africa back to an institution which dealt with a range of different infectious diseases of livestock. But over the last 10-12 years or so my activities have become refocused on Tile area again. It's a really real disease that causes major losses and affects people, which some of the diseases that we work on in Europe have relatively minor impacts on human population. The second reason I guess is that it's just biologically very interesting and challenging and actually can tell us a lot of information not only about specifically about the disease but it might be irrelevant to other diseases both in animals and humans. I think it gives a unique opportunity to really have an impact on this problem. The problem in the past is that a lot of the research has been funded by small projects it's been able it's been possible to make sort of progress in specific areas but it hasn't there hasn't always been the opportunity for people to come together from different disciplines and work collaboratively. More importantly it's kind of integrating work on basic mechanisms of immunity with vaccination which I think is the way forward.
