I am currently a Research Associate affiliated with the Alfred Wegener Institute (AWI) and the Berlin Center for Genomics in Biodiversity Research (BeGenDiv). I was awarded a Humboldt Research Fellowship for Postdoctoral Researchers to carry out an investigation of population structure and connectivity of the Antarctic toothfish (Dissostichus mawsoni) in the Weddell Sea sector of the Southern Ocean. In addition to being the largest fish in the Southern Ocean, the Antarctic toothfish, commonly known as Chilean Sea Bass, represents the most lucrative Antarctic fishery. I am using genetics and otolith chemistry to test population hypotheses rooted in our understanding of local and regional hydrography. On the genetics side, I am working with Camila Mazzoni at BeGenDiv to develop a RADseq technique optimized in Antarctic toothfish, which will provide a detailed picture of population structure based on relatedness. With respect to otolith chemistry, I am working with Thomas Brey at AWI to utilize trace elements and stable isotopes deposited in otoliths to elicit an understanding of population structure derived from provenance and ontogenic movements. This work will help inform fisheries management decisions by CCAMLR and will support the implementation of a Marine Protected Area in the Weddell Sea.
