德国癌症研究所2022年招聘博士后（空间基因组学方向）

Postdoc In Spatial Genomics

DeutschesKrebsforschungszentrum

Description

Position: Postdoc in Spatial Genomics

Department: Artificial Intelligence in Oncoclogy

Code number: 2022-0081

The German Cancer Research Center is the largest biomedical research institution in Germany. With more than 3,000 employees, we operate an extensive scientific program in the field of cancer research.

The laboratory of Dr. Moritz Gerstung (Division of Artificial Intelligence in Oncoclogy) at the German Cancer Research Center (DKFZ) is looking for a postdoctoral fellow in spatial genomics. The group studies cancer evolution using a combination of AI analysis and new experimental technologies 1,2. We have recently co-developed experimental protocols to detect mutations in tissue sections which map how cancers have grown in their tissue context 3. This method, termed base specific in situ sequencing (BaSISS) extends the Cartana/10x ISS protocol. The BaSISS protocol combines sequencing of a tumour to identify mutations and localises these variants in a tumour section with single molecule padlock probes, which are interrogated by cyclic fluorescence microscopy. Our newly developed spot detection algorithm 4 then extracts signals from 100,000s of cells in a tissue, which are assembled into maps of subclonal growth. The protocols also allow for measuring the histopathological and transcriptomic changes acquired during tumour progression.

Job description:

We are looking for an experimental postdoc to apply these spatial genomics technologies to study the evolution of sarcomas and other cancer types. You will work alongside other lab members and in collaboration with the Single- cell Open Lab 5 to pursue our efforts to use spatial genomics for studying cancer evolution in our new lab at DKFZ 6 which opened in September 2021. Being part of an international interdisciplinary team working both experimentally and computationally will offer you a comprehensive training and opportunities to broaden your horizon in many ways. Furthermore, you will have the opportunity to take full advantage of all the training and social activities the DKFZ International Postdoc Program has to offer 7. The starting date is flexible, depending on candidate preferences.

Your responsibilities:

Implement and run BaSISS and general ISS experiments

Run 10x visium spatial transcriptomics arrays on fresh and fixed tissues

Implement other standard in situ hybridisation assays (e.g. RNAscope, NanostringGeoMx) widely utilized in the field
