Beschreibung: We are seeking a highly motivated and talented master or PhD student to join our new group at the Department of Medical Biochemistry and Cell Biology at Sahlgrenska Academy, Gothenburg University, Sweden.

Mitochondria are key organelles that convert chemical energy into ATP by utilizing a system of molecular machines, the respiratory chain complexes. Cells can direct metabolism depending on the availability of certain energy sources. This then requires a reprogramming of metabolism, often accompanied by changes in gene expression and the repression of competing metabolic pathways. In the frame of a five-year project funded by the Knut and Alice Wallenberg Foundation, we aim to unravel the fundamental molecular mechanisms of mitochondrial protein synthesis, its regulation and connection to respiratory chain assembly. In this project, we will study the adjustment of mitochondrial functions in cells exposed to insulin and other stimuli that can inhibit mitochondrial functions including organellar protein synthesis. Our group employs a wide array of methodology including human cell culture, molecular biology, biochemistry, and structural biology.
Successful applicants would have a background in biochemistry, molecular biology or a related field. Previous experience with cell culture or microscopy would be desirable, but is not a strict requirement. Starting date is flexible. Please send a cover letter stating your research interests and a curriculum vitae with your research experience and courses taken, merged into a single pdf file to martin.ott@gu.se
