Job Title

Biohub is the first large-scale initiative bringing frontier AI models, massive compute, and frontier experimental capabilities under one roof. We're building a general-purpose system to accelerate scientific discovery, integrating frontier AI models, biological foundation models, and lab capabilities, with the ultimate goal of curing disease. Our technology powers scientists around the world, translating AI capabilities into tools that accelerate research everywhere.The TeamOur immune cell reprogramming team integrates foundational research on immunology and disease biology with AI-modeling to develop engineered cells that harness our own immune system to detect and treat early signs of age-related diseases, like cancer, Alzheimer's, and Parkinson's. These technologies will enable precise, context-dependent therapeutic responses only when and where it is needed. You can learn more about our work here. Our work brings together three powerhouse universities - Columbia University, The Rockefeller University, and Yale University - into a single collaborative technology and discovery engine.Our VisionPursue large scientific challenges that cannot be pursued in conventional environmentsEnable individual investigators to pursue their riskiest and most innovative ideasFacilitate research by scientists and clinicians at our home institutions and beyondWe are a team of passionate individuals powered by technology, guided by scientific research, and driven by collaboration, working toward a mission to cure or prevent all disease.The Laboratory of Immunogenomics at Biohub in NY () studies the non-coding regulatory genome to understand and address immune dysfunction in diseases like cancer, autoimmune disorders, and aging. We focus on enhancers-non-coding, highly cell-type-specific transcriptional regulatory elements-and their role in shaping immune responses.We develop and utilize genomic technologies, including bulk and single-cell nascent RNA sequencing, genome editing, immune engineering, and CRISPR-based functional screens in patient biopsies, organoid systems, and mouse models. Through computational analysis integrating machine learning and AI, we map enhancer-gene networks and identify disease-driving elements. Our goal is to advance enhancer-guided precision genomic medicine for diseases involving immune dysfunction.The OpportunityWe are seeking a Postdoctoral Fellow to lead research on the immune and stromal components of the tumor microenvironment (TME) in gastrointestinal cancers. The goal is to identify and characterize the cancer-cell intrinsic and extrinsic regulatory mechanisms that influence pro-inflammatory and anti-inflammatory immune dynamics, with the aim of developing new therapeutic targets and improving existing treatments such as immune checkpoint inhibitors and combination therapies.This role will involve in vivo studies using genetically engineered mouse models (GEMMs), syngeneic and patient-derived xenograft (PDX) models, and human patient-derived organoids. The project integrates immunology, cancer biology, stromal biology, and translational research in close collaboration with multidisciplinary teams.What You'll DoImmune Dynamics in the TMEProfile immune cell populations in TME using flow cytometry, single-cell RNA-seq, and spatial transcriptomics.Assess immune cell function via cytokine/chemokine measurement, cytotoxicity assays, and antigen presentation studies.Characterize the balance between pro- and anti-inflammatory cell populations during tumor progression and treatment.Stromal and Fibrosis BiologyCharacterize cancer-associated fibroblast (CAF) subtypes and their impact on immune modulation and therapy resistance.Study extracellular matrix remodeling and fibrosis-associated immunosuppression in tumors.Identify stromal targets that could enhance immune infiltration or therapy delivery.In Vivo ModelsMaintain and use GEMMs, syngeneic, and PDX models of GI cancers.Conduct orthotopic and subcutaneous transplantation studies.Perform pre-clinical therapeutic studies with ICIs, stromal modulators, and other immunotherapies.Monitor tumor progression using in vivo imaging and histopathology.Human-Derived ModelsEstablish and genetically manipulate patient-derived organoids from primary and metastatic tumors.Co-culture organoids with immune cells to model tumor-immune interactions.Apply CRISPR editing to test candidate genes, regulatory elements, and pathways.Data Analysis and DisseminationCollaborate with computational teams to integrate multi-omics datasets and apply machine learning to identify biomarkers and predictive signatures of therapy response.Link experimental findings to patient datasets for translational prioritization.Present at scientific conferences, publish in peer-reviewed journals, and contribute to grant proposals.What You'll BringEssential PhD in Immunology, Cancer Biology, Molecular Biology, or a related field.Expertise in tumor immunology and/or stromal biology, ideally in GI cancers or other solid tumors.Experience with mouse cancer models (GEMMs, syngeneic, PDX).Proficiency in immune profiling and functional assays.Skills in primary immune cell and organoid culture.Strong publication record in relevant fields.Ability to lead projects independently and work in collaborative teams.PreferredExperience with CAF biology, fibrosis, and ECM biology.Familiarity with immune checkpoint blockade and combination therapy studies.Skills in spatial transcriptomics, multiplex IHC/IF, or advanced imaging.Experience analyzing single-cell sequencing data and integrating bulk omics datasets.Working knowledge of CRISPR editing in primary cells or organoids.Interest in translational research and collaboration with clinical partners.CompensationThe New York, NY base pay for a new hire in this role is Postdoctoral Fellow = $93,000.00. This position may be eligible to participate in Biohub's discretionary annual performance bonus program. Bonus eligibility and targets are determined in accordance with Biohub's total rewards philosophy and may vary by role.Benefits for the Whole YouWe're thankful to have an incredible team behind our work.
