Research interests

The cycling of bio-essential trace metals in the marine environment 

Trace metal biogeochemistry: I am interested in the distribution of trace elements (particularly bio-essential elements such as iron and cobalt) in the ocean, both in the dissolved phase and from oceanic particulate material.  

Analytical chemistry: I am very interested in developing and using analytical techniques which allow for the determination of multiple elements from one sample. 

Research degrees awarded to supervised students

Antony Birchill (2013 – 2017, co-supervisor): Cycling of iron in the Celtic Sea.
