Education and career
Ploug grew up in Denmark.[1] She has an M.Sc. (1992)[2] and a Ph.D. (1996) from Aarhus University. Following her Ph.D. she did postdoctoral work at the Max Planck Institute for Marine Microbiology and the University of Copenhagen. Starting in 2006 she was a scientist at the Alfred Wegener Institute for Polar and Marine Research,[3] and in 2008 she moved to Stockholm University where she had a Marie Curie fellowship.[1] In 2006 she became an associate professor at the University of Gothenburg where she was promoted to professor in 2013.[3]
Research
Ploug's early research used fiber optic sensors to measure light in marine sediments.[4][5] She went on to examine how particles assemble in marine systems.[6][7] Her work on particles includes developing methods to quantify bacterial use of particles,[8][9] and the implications for consumption of particles produced by copepods.[7][10] Ploug has developed methods to measure how fast particles sink through the ocean[11] and the rate sinking particles are converted into carbon dioxide.[12] Her recent research has focused on measurements of biogeochemical cycling at the single cell level using Nanoscale secondary ion mass spectrometry.[13][14]
