Jukka was a post-doctoral associate at Indiana University between
1994 and 1996, funded by the Academy of Finland. He took the lab
in a new direction by emphatically pointing out the need for solid
life-history data, which could be used to compare sexual and asexual
morphs of the snail. He also brought key statistical skills, and
a knack for insightful testable questions. Jukka is also the driving
force behind our long-term study of snail-trematode interactions in New
Zealand. A recent paper from this work shows that parasites
evolve to infect common clones in a mixed (sexual and asexual)
population of the snails, which is directly consistent with the Red
Queen hypothesis (Jokela et al. 2009).
Jukka is presently Professor and Director of EAWAG in Dubendorf Switzerland (web page for Jukka).
