Job positions

Open position

PhD Position in Super-resolution RNA Imaging

Topic
Genetically encodable fluorescence markers for imaging of specific RNA molecules in live cells are still very limited. Within the project ‘Super‐resolution RNA Imaging with Aptamer‐ PAINT’, funded by the Baden‐Württemberg Stiftung (collaboration with the Jäschke lab, IPMB, U Heidelberg), we develop advanced light‐up RNA aptamers for live‐cell superresolution localization microscopy applications.

Candidate
We are looking for an excellent, highly motivated person with a degree in (bio)physics, physical chemistry or related fields who is interested in working in an interdisciplinary team and who is strongly committed to careful biophysical experimentation (single molecule imaging) and computer‐based quantitative data acquisition and analysis.
