The Institute

The Centre for Genomic Regulation (CRG) is an international biomedical research institute of excellence, based in Barcelona, Spain, with more than 400 scientists from 44 countries. The CRG is composed by an interdisciplinary, motivated and creative scientific team which is supported both by a flexible and efficient administration and by high-end and innovative technologies.

In April 2021, the Centre for Genomic Regulation (CRG) received the renewal of the 'HR Excellence in Research' Award from the European Commission. This is a recognition of the Institute's commitment to developing an HR Strategy for Researchers, designed to bring the practices and procedures in line with the principles of the European Charter for Researchers and the Code of Conduct for the Recruitment of Researchers (Charter and Code).

The role

The Single Cell and Synthetic Genomics of Blood Formation lab (PI: Lars Velten) at CRG Barcelona is looking for a research technician with experience in genetic screens and primary cell work,  to cover a maternity leave.

Blood formation is an essential, biomedically highly relevant, and complex process of cellular differentiation. Our group works on basic science projects on gene regulation in blood stem cells (e.g. Frömel et al., Cell 2025), and more translational projects in the context of acute myeloid leukemia (AML) and pre-leukemia (e.g. Beneyto-Calabuig et al., Cell Stem Cell 2023). A specific focus is the use of genetic screens (E.g. CRISPR screens, Perturb-Seq, MPRA) in primary hematopoietic stem cell models.

The successful candidate will cover a maternity leave. Additionally, a period for training (overlap) will be covered.

About the lab

My interdisciplinary group investigates the biology of hematopoietic stem cells using a combination of single cell genomics, genetic screens, and computational biology. We strive to develop novel genomic and bioinformatic tools to answer longstanding questions in the field. We cover two main research lines, a) Gene regulation in healthy hematopoiesis) and b) Clonal function in ageing and disease. The lab has been established in January 2020 and currently consists of seven members: Three PhD students, two postdocs and two senior technicians. We have received funding from the European Commission, the Spanish and German government, the Spanish Association Against Cancer and the European Hematology Association.
