1. How do some fish maintain an internal ion homeostasis when the environmental salinity changes?
2. How are environmental contaminants of emerging concern impacting early developmental processes, such as retinal patterning, in local aquatic species?
We use biochemical, molecular and immunohistochemical techniques to address these questions using species of local interest, as well as laboratory fish colonies of species such as stickleback and zebrafish.
