Contributions to Promoting Diversity: For 1997-2008, I was involved with the NOAA Antarctic Marine Living Resources program as the primary scientist aboard ship (Russian vessel) conducting phytoplankton ecology studies in the Drake Passage, Antarctica, for 2-3 months per year. Our collaboration with Chilean Professors involved their students participating in our expeditions, during which I taught and mentored various analytical and methodological techniques for phytoplankton (and microbial) ecology as performed at sea.

Other Activities
