During the last decade he has studied the effect of toxic red tides on molluscs and in recent years he has focused his interest on climate change and its effect on marine organisms of ecological and economic importance, which inhabit the south-austral zone of Chile and Antarctica. The main stressors of climate change have included the effect of sea temperature rise (warming,) desalination (freshening) and acidification, and how these changes can affect the behavior, physiology and ecology of marine organisms.
