Post Doc Instructions: Please do not submit an application to this posting.? To apply for this postdoctoral research opportunity, follow the directions below in ?Applicant Special Instructions?. Department Name/Job Location: This position is in the Department of Internal Medicine, Division of Oncology - Bone Marrow Transplant. This position is for the Medical School Campus. Essential Functions: POSITION SUMMARY : Postdoctoral Research Associate Position Open in the Jaebok Choi Lab in Department of Internal Medicine, Division of Oncology. Area of expertise: Transplant Immunology focused on T cells The Choi Lab is seeking a postdoctoral researcher to work on 1) elucidating the mechanisms underlying the prevention and treatment of graft-versus-host-disease (GvHD) by small molecule inhibitors of Janus Kinases (JAKs), and/or 2) identifying/validating novel genes that differentially regulate GvHD and graft-versus-leukemia (GvL) effect through CRISPR/Cas9 guide RNA library screenings. The long-term goal of the lab is to separate the beneficial GvL effect from GvHD. Please see the departmental website for the detailed information at https://oncology.wustl.edu/people/faculty/Choi/Choi_Res.html . The postdoctoral researcher will have the opportunity to work with collaborators, such as Drs. John DiPersio, Matt Cooper, Kiran Vij, Samuel Achilefu, and Feng Gao, and to develop independent projects. For translational approaches, the postdoctoral researcher may occasionally analyze human patient samples. In addition to high-quality research facilities, career and professional development training for postdoctoral researchers is provided through the Career Center, Teaching Center, Office of Postdoctoral Affairs, and campus groups.
