I am interested in how biotic and abiotic stressors affect animal behaviour
and performance. Biophysical interactions (effect of temperature, water flow,
etc. on species) and biotic interactions (competition, predation, parasitism)
have broad implications for understanding how species persist in their
natural habitat, particularly in the face of environmental change.

My PhD research focused on fish locomotion and the morphological and
physiological adaptations that allow species to respond and adjust to
environmental stressors. I try to understand how the individual performance
of temperate and tropical fishes affects broad-scale ecological patterns
such as population structure and species’ distributions.

My research interests are broad, and include studies on energetics
(metabolism) and performance (kinematics), ecomorphology, behavioural
and physiological ecology, and invasive species in fishes, crabs, and other
aquatic organisms. I like to combine laboratory experiments with field
observations to relate quantitative experimental data with ecological outcomes.
I am also interested in science policy and the open science movement.

In July 2014, I joined the Eco-Ethology lab as a postdoc and I am now
working with Redouan Bshary on the application of biological market theory
to coral reef fishes.

Project outline: Advances in our understanding of ultimate explanations for
the evolution of cooperation have not been matched by similar progress in
understanding proximate mechanisms that underlie cooperative behaviour.
For example, stylised game theoretic models can help us identify which
conditions are necessary for cooperation to evolve but they fail to explain
frequent variation in levels of cooperation seen in nature. We plan to examine
proximate causes of variation in cooperation levels using the client-cleaner
wrasse mutualism, where “client” fishes visit cleaners to have their ecto-
parasites removed. Conflicts of interest arise because cleaners prefer to
eat the protective client mucus rather than the harmful ectoparasites.
The objectives are to (1) identify the relative importance of mechanisms
underlying variation in cooperation, and (2) examine how these
mechanisms interact with changes in service supply to test biological
market theory.
