Dr. Lewis' research involves characterizing the factors that control the growth and reproduction of marine brown algae. Specifically, growth and gametogenesis of microscopic gametophytes of the large and ecologically significant kelps are characterized in response to salinity, pheromones, pH, nutrients, and light.
