Research Interests

His research focuses on the physiological ecology of corals with an emphasis on how corals respond to environmental stress, in particular, the stress of globally rising temperature and CO2.  Over fishing, sedimentation and eutrophication are thought to have been responsible for most the declines in coral abundance and phase shift to macroalgal dominance that have been observed in the last 100-200 years.  However, it is increasingly becoming evident that in the next 50-100 years the greatest threat to the survival of coral reefs is global change, i.e. greenhouse warming and acidification of the ocean.

He takes an experimental approach to gaining an understanding how coral reefs will function in a high CO2 world.  The scale of his experiments have ranged from single coral colonies in respirometry chambers to 100-200 colonies in a flume to a complete community of coral reef organisms in a very large mesocosm. At UM he hopes to build an environmentally controlled coral culturing facility for studying the effects of the temperature and CO2, alone and in combination, on coral photosynthesis, calcification, fecundity, and settlement.  He also plans to get out onto the reefs in the Florida Keys to make observations where natural experiments may be occurring due to variations in residence time.
