About the job

Job Description

Postdoctoral Research Fellow, AI-Guided Functional Immunolog y
Our AI/ML team develops biologically grounded and interpretable machine learning methods to accelerate target discovery across immunology. We are seeking a highly motivated Postdoctoral Research Fellow to develop next-generation perturbation modeling approaches that integrate single-cell transcriptomics, functional genomics, and human organoid models to elucidate immunological disease mechanisms and generate experimentally validated biological insightsf.

• What You'll Do:
• Advance AI/ML methods that connect single-cell foundation models with functional perturbation data.
• Develop interpretable and reproducible computational approaches to predict how genetic and chemical perturbation of immune cells reshape cell states.
• Design and interpret perturbation designs together with experimental groups and feed the resulting data back into the models.
• Develop experiment-selection strategies (active learning, Bayesian optimization) that decide which knockouts the next round tests and characterize how a model-chosen training set biases its own evaluation.
• Design evaluations for out-of-distribution generalization held-out cell contexts, matched-decoy nulls, and the linear and mean baselines a foundation model must beat to earn trust.
• Collaborate with multidisciplinary teams across data science, immunology, functional genomics, and translational research.
• Communicate scientific findings through presentations, publications, and cross-functional discussions.

• You Should Have:
• Strong expertise in machine learning, deep learning, and data science.
• Demonstrated research productivity through publications, preprints, or conference presentations.
• Ability to communicate complex technical concepts to multidisciplinary scientific teams.

• Educational Requirement:
• Must currently hold a PhD OR
• Receive a Ph.D. no later than spring 2027
• Ph.D. in Computational Biology, Bioinformatics, AI/ML, Computer Science, Immunology, Bioengineering, Statistics, or a related quantitative discipline

• Required Experience Skills:
• Experience with single-cell omics analysis, representation learning, or biomedical data analysis.
• Strong expertise in machine learning, deep learning, and data science.
• Proficiency in Python and deep learning frameworks such as PyTorch.
• Experience applying and evaluating deep models on high-dimensional biological data (single-cell, imaging, or similar).
• Proficiency in Foundation Models, Perturbation Modeling, and/or Organoid Models.
• Experience with CRISPR and target discovery.

• Preferred Skills and Experience:
• Single-cell foundation models, transformers, and representation learning.
• Genetic perturbation modeling: CRISPR screens, Perturb-seq, or arrayed knockouts.
• Wet-lab experience, especially involving organoid, iPSC, or immune co-culture model systems.
• Background understanding of, or experience working in, immunology.
• Experimental design, active learning, or model benchmarking and evaluation.
• Publications in venues such as NeurIPS, ICML, ISMB/RECOMB, Cell Systems, Nature Methods, or related journals.
