Computational biologist in single cell OMICS applied to immune-oncology
CDD · Postdoc · 24 mois (renouvelable) Bac+8 / Doctorat, Grandes Écoles Cancer Research Center of Lyon · Lyon (France)
Date de prise de poste : 15 juin 2022
Single cell OMICS, onco-immunology
We are seeking a highly motivated and scientifically driven computational biologist/bioinformatician who will bring his/her expertise to contribute to the efforts of the team in identifying key immune surveillance pathways and immune escape mechanisms operating in tumors. The successful candidate will take the lead of a project that aims to identify novel immunosurveillance pathways by performing a comprehensive comparison of tumors from patients with a paraneoplastic neurological syndrome (PNS) and conventional non-PNS tumors through computational analysis of single cell RNA-sequencing data of immune cells, tumor cells and stromal cells, antigen receptor sequencing data and of spatial data of the tumor immune contexture based on multispectral immunofluorescence tissue imaging. It follows our recent observations with the team of J. Honnorat (INMG Lyon) that ovarian and breast carcinomas from PNS patients differed from their non-PNS counterpart by a massive infiltration by CD8 T cells and antibody producing plasma cells, as well as signs of tumor immune attack, indicating efficient and concomitant in situ anti-tumor cellular and humoral immunity. This project is part of a large effort of the team to discover novel tumor immune surveillance pathways using single cell OMICS in early versus advanced tumors, for which the candidate is also expected to participate according to his/her skills.
Contract: 2 years with possible extension to 3 years.

The team “Cancer Immune Surveillance and Therapeutic Targeting” (CISTAR) is part of the Cancer Research Center of Lyon (CRCL, www.crcl.fr) and is composed of researchers, clinicians, technicians and PhD students all devoted to identify new tumor immune surveillance and escape networks to improve cancer treatments. It already hosts 2 bioinformaticians and collaborate with the CRCL Gilles Thomas bioinformatics platform since several years. The team benefits from long-standing interactions with clinicians of CLB and HCL and is part of various networks/consortiums, including the RHU-BETPSY, which fund the position. The CRCL is a renowned and dynamic research center which benefits from state-of-the-art technological facilities for flow cytometry, cell and molecular biology, bulk and single cell sequencing, spatial transcriptomics, spatial tissue imaging and in vivo/ex vivo models.
Interested candidates should submit a motivation letter, CV and contact details of 2 references to Bertrand Dubois (Bertrand.firstname.lastname@example.org). The position is to be filled as soon as possible. The closing date for applications is June 1st 2022.
