She is an elected member of the Royal Danish Academy of Sciences and Letters and has received the Order of the Dannebrog.
[12] Her research includes investigations bacterial attachment to surfaces,[13] and quantification of hydrogen sulfide production by bacteria associated with fish.
[14] From 2006 until 2007, Gram participated in the Galathea 3 expeditions,[1][15] and she is using the bacterial cultures initiated during the project to mine bacteria for chemical compounds that may be useful to people.
[16] Gram's research extends to investigations of the global distribution of bacterial species,[17] and an examination of how the presence of varying nutrients alters the chemical compounds produced by bacteria.
[18] In 2008, Gram received Tagea Brandt Rejselegat, an award given to Danish women to recognize significant contributions in science, literature, or art.
