Research Interests

I am interested in all aspects of marine ecology, but most of my work has focused on seaweeds. In particular, my research involves understanding the consequences of human-induced alterations in intertidal community structure. This work has two components: 

a) monitoring for changes in algal communities. This work is taking place in Barkley Sound & the Broughton Archipelago (British Columbia). As an continuation of my M.Sc work, I am also collaborating with Dr. Gary Saunders to maintain a long-term monitoring program in the Bay of Fundy (New Brunswick).

b) using manipulative experiments to determine the ramifications of change in seaweed communities, with specific reference to resultant change in invertebrate communities. This work takes place in Barkley Sound, and is based out of the Bamfield Marine Science Centre

Other research interests include:

1) Communication of science through video and multimedia. I teach science filmmaking workshops with Jeff Morales (National Geographic Film & Television, VONIGO Films). To learn more about this work, visit

2) Measurement of biodiversity. I am particularly interested in understanding the relationships between taxonomic and functional diversity. Major questions also surround a) the benefits and consequences of sampling and analysis at various data resolutions (e.g. coarse taxonomic levels, functional groups, diversity indices, etc.) ; and b) the incorporation of taxonomic information into diversity indices. 

3) Biostatistics, with a focus on nonparametric multivariate analysis of biological community structure 

4) Understanding the relative importance of positive interactions in structuring marine biological communities.

5) Marine conservation issues. To facilitate understanding about the effects of human influence on marine intertidal communities, I organized a marine biodiversity workshop in April 2004.
