We have done a number of studies of host-parasite interactions. This work started as a collaboration with McGill Professors Marilyn Scott and Gregor Fussmann and Dalhousie Professor Paul Bentzen. It has, of course, been carried forward by the various students we have taken together as can be seen in the papers listed below. Most of the work focuses on the guppy-Gyrodactylus system (see the cool video below); but, in collaboration with PhD student Victor Frankel and STRI scientist Mark Torchin, we also worked on invasive host-parasite communities in Panama.
