Postdoctoral positions are available in the laboratory of Dr. Jian Xu at Children’s Research Institute (CRI), UT Southwestern Medical Center to study the gene regulatory processes that control stem cell development and cancers, particularly the mechanisms that control non-coding genomic elements, epigenetic gene regulation and cellular metabolism. We employ genomics, epigenetics, genome editing, metabolomics, and mouse genetics to define epigenetic and genetic programs that control normal stem cell development, and how these processes go awry in cancer progression.
Our laboratory is equipped with cutting-edge genomics, molecular biology and bioinformatics platforms, and has access to many shared facilities including an in-house illumina sequencer, 10xGenomics single-cell technologies, metabolomics, transgenic mouse core, imaging, and flow cytometry. Our team brings together enthusiastic scientists with diverse backgrounds, and provides a wide range of perspectives in a multi-disciplinary and collaborative team setting. Since we established the laboratory in 2014, our team has published a series of impactful papers, which include:
• Development of a dCas9-based affinity purification approach (‘CAPTURE’) for in situ analysis of chromatin interactions that regulate genomic enhancers (Cell 170:1028, 2017)
• Mitochondrial biogenesis and metabolism are regulated by post-transcriptional through mTOR-mediated effects on protein synthesis during erythropoiesis (Nature Cell Biology 19:626, 2017)
• Reported that loss of EZH2, the histone methyltransferase, reprograms branched-chain amino acid (BCAA) metabolism to drive leukemic transformation (Cancer Discovery 9:1228, 2019)
• Reported an integrative pipeline to identify pathogenic non-coding variants connecting enhancer dysregulation with nuclear receptor signaling in leukemia (Cancer Discovery 10:724, 2020)
• Discovered that the epigenetic silencing of LINE-1 retrotransposons is a selective dependency of myeloid leukemia (Nature Genetics 53:672, 2021)
Candidates must hold a Ph.D. and/or M.D. degree with a strong background in molecular biology, cancer biology, mouse genetics, bioinformatics and/or a related field. The ideal candidate will exhibit independence, flexibility and creativity with a record of scientific productivity. Previous experience in epigenetics, metabolism, single-cell genomics, computational biology, mouse genetics, and/or hematology-oncology is strongly preferred.
Interested individuals should send a CV, a short summary of research interest and experience, and a list of three references to:
