Dr. Amy Maas


Amy is a comparative physiologist and biological oceanographer whose research addresses fundamental questions about how the environment influences the distribution and biology of marine invertebrates. Based on this understanding she works to identify how climate change will impact biogeochemical cycling. Using transcriptomics, microscopy and comparative physiology, one major focus of Amy's studies is understanding how thecosome pteropods respond to ocean acidification. Her current research projects also include studying pteropod distribution and seasonality at the BATS site, explorations of circadian rhythms and diel vertical migration in open water zooplankton to better understand how environmental changes impact carbon flux, and comparative transcriptomics of multiple plankton species.

Amy received her PhD from the University of Rhode Island in 2011, where she worked in Antarctica and at sea in the Eastern Pacific exploring the impacts of climate-related variables on pteropods living in extreme environments. As a Postdoctoral Scholar/Investigator at Woods Hole Oceanographic Institution she worked in the Biology Department studying regional and seasonal patterns of pteropod metabolic and transcriptomic sensitivity to ocean acidification (2011-2015). Prior to joining BIOS in 2015 Amy was also jointly appointed at the University of Connecticut Marine Science and Technology Center as an Assistant Research Scientist.
