Karolinska Institutet, The Department of Medicine, Huddinge

About the position
This is a new post funded through the Knut and Alice Wallenberg Stiftelsen, based within the Department of Medicine Huddinge. The project is focused on single cell analysis and modeling of normal and malignant hematopoiesis. The postholder will report directly to the Principal Investigator, Professor Sten Eirik Jacobsen (http://ki.se/en/medh/sten-eirik-w-jacobsen-group).  

This is an exciting position that allows the postholder to apply a variety of statistical and computational techniques to analyze and interpret a wide range of genomic data sets, from single-cell RNA-seq to the correlation of whole genome sequencing data with clinical outcome in patient cohorts. There is scope for developing novel analysis methods in collaboration with scientists at Karolinska Institutet, as well as together with external collaborators.

About The Jacobsen lab
The Jacobsen lab comprises an international collaborative team focused on understanding at the single cell level the cellular and molecular pathways governing the earliest fate decisions in normal hematopoiesis [1-4] and how these are dysregulated in hematologic malignancies [5-9]. This is studied in mouse models, as well as in relevant patients. Key technologies applied towards these research questions include high-throughput DNA and RNA sequencing including single cell analysis, genetic fate-mapping using next-generation-sequencing technology, flow cytometry, mouse genetics and various in vitro and in vivo stem cell assays. The postholder will have the opportunity to lead projects focused on the analysis of single-cell RNA-seq data to understand heterogeneity of normal and leukemic hematopoietic stem and progenitor cells (e.g. see our recent paper in Nature Medicine [10]), as well as generate testable models from single cell hematopoietic stem cell functional data (e.g. see our recent paper in Nature [2]).

Projects will be pursued in part at the Center for Hematology and Regenerative Medicine (HERM; http://ki.se/en/medh/herm), and in part at the Department of Cell and Molecular Biology (CMB; http://ki.se/en/cmb/startpage). The Jacobsen lab also has close interactions with world leading research groups, and the recruited bioinformatician will benefit from interactions in this collaborative network. Of particular relevance, the bioinformatician will interact closely with the Professor Seishi Ogawa, a world leader on next-generation sequencing of cancer [11, 12], and a guest professor at the Karolinska Institute, as well as Assistant Professor Petter Woll, a group leader at the Karolinska Institute focused on studies of normal and malignant hematopoiesis and a close collaborator of Professor Jacobsen [2, 8, 9]. A key focus will be to apply up-to-date statistical and computational methods to unravel important biological questions, specifically analysing and integrating large-scale single cell sequencing, cell biology and clinical data sets. The candidate will have access to state-of-the-art computational tools available through the Swedish National Infrastructure for Computing (SNIC) and Uppsala Multidisiplinary Center for Advanced Computational Science (UPPMAX) providing large scale high performance computing resources, storage capacity and advanced user support (https://www.uppmax.uu.se). The successful candidate must demonstrate excellent statistical and programming skills with the ability to manage simultaneous projects to meet deadlines.

  • Keep detailed, accurate and comprehensible records of work performed and communicate developments and results to colleagues on a regular basis, as required.
  • Communicate and meet with the group leaders on a regular basis and with external collaborators as the need arises.
  • Regularly present data at laboratory meetings
  • Clearly present at scientific meetings, and to undertake further training as appropriate.
  • Maintain confidentiality regarding research data when interacting with non-collaborating researchers.
  • Work as part of a team and independently as required, organizing work efficiently, prioritising workload and taking personal responsibility for assigned tasks.
