We are a computational immunology group with a combination of big data analysis and immunology domain expertise. Our interests include both developing new computational methods and applying these methods to study human immune responses. Specific areas of focus include:
We are always open to new collaboration opportunities with basic science and clinical research groups. Please send us an email if interested. For research updates, follow us on twitter (@skleinstein).
High-throughput B cell receptor (BCR) repertoire sequencing
Next-generation sequencing (NGS) technologies have revolutionized our ability to carry out large-scale adaptive immune receptor repertoire sequencing (AIRR-seq) experiments. AIRR-seq is increasingly being applied to gain insights into immune responses in healthy individuals and those with a range of diseases, including autoimmunity, infection, allergy, cancer and aging. As NGS technologies improve, these experiments are producing ever larger datasets, with tens- to hundreds-of-thousands of single cells (or tens- to hundreds-of-millions of BCR sequences when run in bulk), requiring the development of new computational methods to manage and analyze these “Big Data”. For an overview, please check out our review.
We have developed many widely used computational methods for bulk and single-cell AIRR-seq data processing and analysis. These methods are available to the wider scientific community through the Immcantation framework, which provides a start-to-finish analytical ecosystem for high-throughput AIRR-seq datasets, with a focus on B cell receptor (BCR) repertoire profiling. Working in close collaboration with basic experimental and clinical groups, we have been applying our methods to gain biological insights in several systems, including: infection (SARS-CoV-2, HIV, Salmonella, West Nile virus, Lyme), vaccination (influenza), allergy (allergic rhinitis, atopic asthma) and autoimmune disease (Multiple Sclerosis, Myasthenia Gravis). We are also active members of the AIRR Community.
Multi-omic immune signatures of human infection and vaccination responses
Individual variations in immune status and function produce significant heterogeneity in infection and vaccination responses. For example, West Nile virus infection is usually asymptomatic, but can cause severe neurological disease and death, particularly in older patients. Our research leverages recent advances in immune profiling methods to characterize diverse states of human immune system (in health and disease, and following infection and vaccination). We have developed several computational methods for large-scale genetic network modeling, including:

A major biological focus area for this research is the response to influenza infection and vaccination. As part of the multi-institutional Program for Research on Immune Modeling and Experimentation (PRIME), we developed data-driven models for the response of multiple human cell types to infection with different strains of influenza (including the infamous 1918 pandemic strain). We also study influenza vaccination responses as part of the NIH/NIAID Human Immunology Project Consortium (HIPC) and the SARS-CoV-2 infection response as part of IMPACC.
