👥Biography 个人简介
Elana J. Fertig, PhD is Professor of Oncology and Director of the Convergence Institute at Johns Hopkins University School of Medicine, where she leads a research program integrating computational mathematics, machine learning, and multi-omics biology to understand cancer progression and treatment resistance. Dr. Fertig is best known for developing CoGAPS (Coordinated Gene Activity in Pattern Sets), a Bayesian non-negative matrix factorization algorithm that decomposes multi-omics datasets (bulk RNA-seq, scRNA-seq, ATAC-seq, spatial transcriptomics) into biologically interpretable transcriptional programs, widely used to identify cancer-associated gene activity patterns across patient cohorts and single cells. Her ProjectR framework enables transfer learning of NMF-derived patterns across datasets and modalities, allowing computational transfer of biological programs from training cohorts to new datasets, enabling cross-study generalization of cancer molecular signatures. Dr. Fertig's laboratory has made major contributions to understanding treatment resistance in head and neck, colorectal, and pancreatic cancers using multi-omics single-cell approaches, identifying transcriptional programs that emerge under therapeutic selection. She co-directs the JHU Convergence Institute for Cancer Informatics and leads multi-institutional computational oncology consortia integrating multi-omics data from clinical trials. Dr. Fertig is a computational biologist whose mathematical foundations and cross-disciplinary training make her work uniquely rigorous at the interface of AI, genomics, and cancer biology.

🎓Key Contributions 主要贡献
CoGAPS — Bayesian NMF for Multi-Omics Cancer Pattern Discovery
Developed and maintains CoGAPS (Coordinated Gene Activity in Pattern Sets), a widely-used Bayesian non-negative matrix factorization algorithm for decomposing multi-omics datasets into interpretable transcriptional activity patterns. CoGAPS identifies latent biological programs in bulk RNA-seq, scRNA-seq, and ATAC-seq data that correspond to cell state transitions, pathway activities, and microenvironmental interactions in cancer, and is distributed as an open-source R/Bioconductor package with tens of thousands of downloads. It has been applied across cancer types and therapeutic contexts to identify treatment-predictive transcriptional signatures and microenvironmental programs.
ProjectR — Transfer Learning for Cross-Omics and Cross-Cohort Pattern Generalization
Developed ProjectR, a transfer learning framework that projects NMF-learned biological patterns from reference datasets onto new omics data across different modalities (bulk to single-cell, RNA-seq to ATAC-seq, human to mouse), enabling computational knowledge transfer of cancer biology insights across studies. Published in Bioinformatics with widespread adoption, ProjectR enables cross-study generalization of tumor transcriptional programs learned from one clinical cohort to new patient datasets, and has been applied to transfer bulk RNA-seq resistance signatures to single-cell and spatial transcriptomics analyses.
Single-Cell Multi-Omics of Treatment Resistance in Head and Neck and GI Cancers
Applied CoGAPS, scRNA-seq, and integrated multi-omics to characterize transcriptional plasticity and resistance mechanisms in head and neck squamous cell carcinoma, colorectal cancer, and pancreatic cancer under immunotherapy, targeted therapy, and radiation treatment. Identified epithelial plasticity programs, EMT-like transcriptional states, and immunosuppressive microenvironmental programs that emerge under therapeutic selection pressure, providing molecular targets and biomarkers for overcoming treatment resistance in multi-institutional clinical datasets.
Spatial Transcriptomics AI — Tumor Microenvironment Spatial Organization
Extended NMF and transfer learning methods to spatial transcriptomics platforms (Visium, Slide-seq, MERFISH), developing computational frameworks for identifying spatially organized gene expression programs in tumor microenvironments. Demonstrated that spatial co-localization patterns of cancer cell states and immune infiltrates revealed by AI methods predict response to immunotherapy and targeted therapy, and published methodological advances in spatial omics integration that enable joint analysis of spatial gene expression and protein marker data.
