Thesis Title: "Understanding the role of Chlorophyll Fluorescence in Nutrient Stress"
My PhD project focuses upon nutrient stress in phytoplankton, particularly iron limitation. My research interests in this area are:
Impact of iron in HNLC areas upon phytoplankton photosynthesis and growth.
Molecular identification of phytoplankton acclimation responses.
Understanding the photosynthetic adaptation of phytoplankton groups to nutrient limitation.
The use of chlorophyll fluorescence and other biophysical techniques to diagnose nutrient limitation.
