Job description

Host team and institute: INSERM U944 - Institut de Recherche Saint-Louis – Genomes and Cell Biology of Diseases. - Website: - Address: Hôpital Saint-Louis - 16, rue de la grange aux belles, 75010, Paris.

Saint-Louis Research Institute was created in 1958 by Jean Bernard and Jean Dausset (Nobel Prize), aiming to achieve excellence in research and teaching, in the fields of hematology, oncology, cell biology, immunology, virology, genetics and therapeutic biotechnologies. Our research institute is located in the center of Paris within the Saint-Louis campus, and benefits from a close relationship and collaboration with Saint-Louis hospital. The institute is affiliated to the doctoral school of “Hematology, Oncology & Biotherapies” and hosts the “European School of Hematology”, thus participating to the training of over 2000 researchers and clinicians every year. Since 2020, Saint-Louis Research Institute is also the home of the ambitious “National Leukemia Institute THEMA”, which seeks to develop public-private partnerships to cure leukemia in 10 years.

Our research unit (UMR U944: genomes, cellular biology & therapeutics), has an internationally recognized research program with world-renowned leukemia researchers, such as Jean Soulier, Hugues de Thé and Alexandre Puissant. Consequently, intellectual interactions among our department members are fostered by a number of weekly research seminars. Our research unit is composed of 6 groups whose research encompasses a broad spectrum of fields, including basic virology, cell biology, cancer genomics, cancer biology and leukemia research, yeast biology, functional studies of post-translational modifications and chromosome biology. Most of the studies carried out by our team bridge several of those fields and have implications in translational research, together with the clinical groups of Saint-Louis hospital. The team works in close partnership with Saint-Louis Hospital Clinical Investigations Center (INSERM-CIC 1427) to accelerate the clinical translation of our lab discoveries. Our team also benefits from a privileged access to a large variety of institutional core facilities, including a fully equipped animal facility, a Fluorescence Activated Cell Sorting and flow cytometry facility, a sequencing facility, and an imaging facility.

Available position: An EHA funded two-years post-doctoral position (possible extension of three extra years) will be opened in March 2021 in a young dynamic team led by Dr Lina BENAJIBA, a physician-scientist focusing on target identification and drug discovery in Acute Myeloid Leukemia. 

Project description: Our team develops new translational research strategies focused on the identification of druggable oncogenic targets to pave the road for successful acute myeloid leukemia (AML) treatment. The post-doctoral fellow will seek to dissect the key role of the bone marrow (BM) niche in sustaining AML and regulating drug resistance, aiming ultimately to develop concomitant “seeds” and “soil” leukemia targeting strategies to improve patients’ prognosis. Novel niche-leukemic crosstalk-induced dependencies will be unraveled using high-throughput functional screening methods in an ectopic humanized BM-AML organoid specifically engineered for large scale target discovery. He/she will then shed light on the mechanistic underpinnings of the BM-leukemia crosstalk using transcriptomic-, epigenomic- and microscopy-based approaches.
