Microbial DNA in deep sediments and the Greatship Manisha's 'genome'

The promise of genomics Each and every living organism, from humans to trees to animals to microbes, has its structure and function described in its genome. This genome is a collection of molecules called chromosomes, with each chromosome comprising a single ... Read more

Man vs. Machine: Counting microbes at the bottom of the Baltic

The microbiology component of IODP expedition 347 to the Baltic Sea is well and truly underway, with drilling of our first hole dedicated to mi ... Read more

Sterile techniques on a dirty drillship

The deep subsurface is an energy-limited environment for microorganisms, which makes for a very low density of microbial cells. 100 m below the seafloor there are up to 100,000X fewer cells than in sediment on the seafloor. This low cell density means that microbes ... Read more

IODP Expedition 347 in the Baltic Sea: pre-cruise preparations in Copenhagen

This is the first post in my blog covering Expedition 347 of the Integrated Ocean Drilling Program (IODP): "Baltic Sea Paleoenvironment", an expedition that will carry out scientific drilling into the Baltic seafloor for the first time ever. For my co-blogger ... Read more

About me

Microbiologist, postdoc at the Center for Geomicrobiology, Aarhus University

I was born in Perth, Western Australia. I have a bachelor's degree in Biochemical Engineering from Jacobs University Bremen in Germany, and a master's and PhD in Environmental Engineering and Science from Stanford University in the United States.

I have been working as a postdoc in the Center for Geomicrobiology in Aarhus since October 2012. My research focuses on adaptations that allow microbes to be active under conditions of extreme energy limitation in the deep subsurface.
