Corals & Climate Change Laboratory People

Dr. Chris Langdon

Langdon is an associate professor in the department of Marine Biology and Fisheries at the Rosenstiel School of Marine and Atmospheric Science. With a deep knowledge of the chemistry and the biology of oceans, his research interests are linked to understand how coral reefs will be impacted by global warming and ocean acidification.

He is co-founder of the South Florida Coral Reef & Climate Change Lab. Langdon pioneered the use of moesocosms and an experimental approach to study the impact of ocean acidification on coral reefs at Columbia University’s Biosphere 2 Center in Tucson, AZ.

Langdon got his Ph.D. in Biological Oceanography from the University of Rhode Island in 1988

Nancy Muehllehner, Ph.D. student

Muehllehner is interested in physiological ecology and marine conservation. For her M.A., Nancy studied the biomineralization of two coral species to see whether morphological plasticity played a role in the response of these species to changing carbonate concentrations in seawater.

Muehllehner is currently researching selective pressure that the combined effects of increasing seawater temperature and changes in the carbon buffering system will have on marine ecosystems. Her particular interest is how this selective pressure will affect different biomineralizing species/genera and how this response could be altered by the history of abiotic conditions experienced by these organisms.
