Job Description:

We are seeking a highly motivated and creative PhD level post-doctoral candidate to explore early stage research on the mechanism of action of the integrated stress response in the regulation of fetal hemoglobin (HbF)  and erythropoiesis in sickle cell disease. Heme-regulated Inhibitor (HRI) kinase has recently been shown to play a role in the regulation of HbF in human erythroid cells but further questions on the  mechanism of action remain. The successful candidate will provide scientific leadership and play a pivotal role in advancing the understanding of HbF induction and erythroid differentiation through the stress response pathway in the pathology of sickle cell anemia. The candidate will be utilizing available novel transgenic mouse models, human donor samples and cell lines to further advance understanding of this pathway.  The candidate will benefit from collaboration with other scientists across Sanofi and will assume responsibility to complete leading edge research for presentation in major scientific meetings and publication in high impact journals. The ideal candidate possesses an understanding and research experience of the field of hematology.  Experience in sickle cell disease is highly desirable.


  • Lead research efforts in Sanofi Rare Blood Disorders to execute cutting edge research to understand the mechanism of action of the integrated stress response in the regulation of HbF induction and erythroid differentiation in sickle cell disease.
  • Characterize erythroid differentiation and the effect of the stress response using genetically engineered cell and mouse models to further understand the role of specific elements of the stress erythropoiesis response and its implication in sickle cell disease.
  • Maintain a working knowledge of current experimental techniques and literature in the field of stress erythropoiesis, sickle cell disease and hemoglobinopathies.
  • Share and present scientific results to multi-disciplinary research groups and at external meetings or conferences.
  • Complete leading edge research and author scientific manuscripts for publication in high impact journals.
  • Work well with colleagues in a matrixed, fast-paced pharmaceutical research environment.

Qualifications – “the ideal candidate”:

  • Has relevant expertise in in vivo models and ex vivo studies and is experienced in handling of small animals and animal models of disease
  • Must have experience in tissue culture, cell-based assays, flow cytometry and ex vivo assays. An understanding of molecular biology tools including but not limited to Crispr-based technology is desirable.
  • Possesses an understanding of research in red blood cell pathology, hemolytic anemias or hemoglobinopathies.
  • Is up-to-date on relevant literature and applies knowledge to current issues in hematology and sickle cell disease.
  • Effectively communicates and collaborates in a multi-disciplinary team environment.
  • Can work independently and proactively; is a self-starter and results-driven.
  • Has a track record of completing independent research and publishing and presenting results.
  • All candidates must have permanent US work authorization. No visa sponsorship will be provided.
