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.

 

New Publication!

Postdoc Matt Harke authored a paper, Periodic and coordinated gene expression between a diazotroph and its diatom host” in The ISME Journal.  The work describes the relationship between a diatom and its friend, a nitrogen-fixing cyanobacteria.  Want to learn more about the importance of this work and how it was done?  Check out the LDEO press release here.
