I am currently interested in the physiological response of marine intertidal algae to environmental stressors. I use a combination of biophysical and physiological tools to describe the energy allocation of Fucus spp. in light of changes in environmental conditions. My field research explores the physiological responses of Fucus to environmental stressors (i.e., temperature and aerial exposure) through the use of temperature and humidity sensors, pulse amplitude modulation (PAM) fluorometry, and spectral radiometry.


Sessile intertidal organisms, particularly Fucus spp., are subjected to highly variable conditions, often experiencing temperature, humidity, and nutrient fluctuations that range several orders of magnitude during the course of a tidal or diel cycle. The question of how changes in environmental conditions will affect organisms already living at environmental extremes remains a vital consideration anent global climate change. By synthesizing empirical measurements and biophysiological modeling, we will be able to better understand how intertidal algae will respond to changes in their environment as the global climate changes. This will provide for a comprehensive understanding of energy allocation and development in ecologically important organisms in rocky intertidal systems.
