DESCRIPTION:Much of the research in disease ecology and evolution has trad
 itionally focused on a one host–one parasite framework. And yet\, in nat
 ural systems\, hosts are usually co-infected by multiple parasites\, and m
 any parasites can infect several host species. My research aims to underst
 and how these real-world complexities drive the ecology and evolution of p
 arasites and their hosts. First I will address how interactions between co
 -infecting parasites can have implications for host health and disease tra
 nsmission. First by building a conceptual framework for understanding how 
 parasite communities might interact within a host\, and then by showing pr
 eliminary data from field experiments aimed at understanding stability and
  resilience in parasite communities.  The second part of my talk focuses o
 n understanding how parasites are able to persist on multiple hosts\, and 
 how these multi-host parasites may contribute to host shifts and disease e
 mergence. To address these issues I will discuss recent work on pathogen s
 haring in wild primates\; specifically addressing how phylogeny and geogra
 phy are likely to determine which parasites infect which hosts\, and how t
 hese patterns can be translated into risk maps\, which may help predict wh
 en and where diseases may emerge within wild primates and from primates to
  humans.
