Impaired differentiation is a critical feature of colorectal cancer. By utilizing a multidisciplinary approach, we aim to design and develop the next generation of therapeutics that induce differentiation of colorectal cancer. The Sethi Laboratory is looking to recruit an exceptional postdoctoral fellow to join their dedicated, diverse, and collaborative team. We seek a highly motivated, creative, collegial, and diligent M.D., Ph.D., or M.D./Ph.D. postdoctoral research scholar with a strong background in molecular biology and experience in functional CRISPR screens, epigenomics, and perturbation single-cell transcriptomics.

The Sethi Laboratory is in the Medical Oncology Department at Dana-Farber Cancer Institute and Harvard Medical School and part of the Cancer Program at the Broad Institute, Harvard Digestive Disease Center, and Gastrointestinal Malignancies at Dana-Farber/Harvard Cancer Center. Our overall goal is to combine clinical observations and patient-derived data with rigorous basic science investigation to yield opportunities for impactful translational advances. Our passion for investigative research is fundamentally dependent upon its power to generate a deeper understanding of human disease and ultimately improve patient care. We are particularly committed to defining the fundamental mechanisms underlying gastrointestinal cancers with the hope that such insight will translate into new prevention and treatment methods (https://sethilab.danafarber. org/). Our work has been published in journals such as Cancer Cell, Nature Genetics, and Gastroenterology.

We utilize molecular biology, biochemistry, cell biology, and organism models to study stem cell biology, gene regulation, epigenetic regulation, genetic dependencies, and drug discovery. Genome-wide molecular analyses of human and murine models routinely executed in the lab include WES, WGS, RNA-seq, single-cell RNA-seq, ChIP-seq, ATAC-seq, CRISPR genetic screens, and drug compound screens. We utilize genetically engineered, carcinogen-induced, nude xenograft, human and murine neoplastic organoids, and PDX mouse models to investigate the molecular mechanisms underlying gastrointestinal cancer development.


  • Independently design, manage, and perform research.
  • Proficient in interpretation of data.
  • Directly supervise technical assistants.
  • Actively mentor junior team members with a desire to teach.
  • Actively participate in group meetings.
  • Prepare scientific presentations and publications.
  • Interact with collaborators.


  • Candidates who have demonstrated rigorous basic and translational research during their M.D. or Ph.D. training will be considered.
  • Experience, expertise, or particular interest in gastrointestinal precancer and cancer research is a plus.
  • Significant experience in standard laboratory techniques (including flow cytometry, tissue culture, PCR, western blots, etc.) is required.
  • The candidate should be highly motivated, dedicated, and a team player.
  • Research or work experience in functional CRISPR screens, epigenomics, and perturbation single-cell transcriptomics, molecular biology, and biochemistry highly preferred.
