I am interested in symbiotic interactions involving snails, particularly epibionts in the genus Crepidula that use snails or hermit crabs as hosts.  I have been looking at the extent to which these interspecific associations are obligate, the length of interactions between particular individuals, the various specific requirements of the interactions (including restrictions to particular species of hosts), and the costs and benefits incurred by each participant.  Most of my work has involved Crepidula adunca in Washington state, and I have recently started examining a parallel system in New Jersey involving Crepidula convexa.
