Sonya Dyhrman’s LAb at Lamont Doherty Earth Observatory of Columbia University

Microbial Oceanography Group

Members of the Dyhrman group are broadly interested in how phytoplankton interact with their geochemical environment, looking at
the interface of microbial physiology and the biogeochemical cycles of nitrogen and phosphorus. 

Group members are using a suite of approaches  to examine nutrient assimilation in model cultures and field populations.  This research emphasis provides advanced training for graduate students and is also used as a framework for the development and implementation of inquiry-based educational activities for children.
