My research integrates neuroscience, endocrinology, physiology, development, general biology of fish and environment. The aim of this research is to evaluate environmental impacts on the fish brain and endocrine systems with emphasis on important aquaculture, restoration and wild fish populations (e.g. salmon and cod). This knowledge will be use to develop molecular tools to monitor and evaluate brain structure and function in a wide range of situations in fish.

 

The purpose is to identify environmental factors that regulate or disrupt brain development and/or function in order to improve rearing strategies designed specifically for aquaculture or enhancement and restoration of wild populations. Why? Disruption of proper brain development can lead to altered endocrine and physiological development that will have consequences on growth, survival and life history trajectory.
