Chief, ImmunoTechnology Section

Major Areas of Research

  • Characterization of antigen-specific lymphocyte function and differentiation in vivo, following vaccination or infection
  • Identification of protective SIV and HIV envelope antibody responses
  • Development of new single-cell measurement technologies

Program Description

The ImmunoTechnology Section (ITS) is dedicated to understanding the roles and interactions of the individual components of the mature central immune system, with a particular eye toward the changes occurring during acute or chronic antigenic challenge. In general, we are looking for immunological correlates of protection (for vaccines) and correlates of pathogenesis (in disease).

Using high-content, high-throughput single-cell technologies (flow cytometric and transcriptomic), we are defining the functional repertoire of antigen-specific T and B cells and how these differ across vaccine regimens and infections. Using the nonhuman primate model, we can interrogate these cells from different tissues throughout the body, studying homeostasis, differentiation, and homing in vivo. We promote selected assays for use in clinical studies, in search of new assays to define protective immune responses.

We are also actively involved in the development and advancement of single-cell technology: instrumentation, reagents, analysis, and assays. We carry out a wide range of collaborations to bring our unique and advanced technology (18-color flow cytometry) to other laboratories at the Vaccine Research Center (VRC), NIH, and around the world. More recently, we have begun to integrate this technology with single-cell transcriptomics to provide an unprecedented view of transcriptional, post-transcriptional, and post-translational regulation at the single-cell level. We are working on new flow cytometric technologies to extend beyond 25 parameters.

We are actively working on new bioinformatic approaches to analyze the complex datasets arising from these studies. We developed a widely-used analysis and graphing program, SPICE, for summarizing large flow cytometry data outputs; we are working on a similar project, SPONGE, for single-cell transcriptomics data.


Dr. Roederer received his B.S. in chemistry in 1983 from Harvey Mudd College, Claremont, California, followed by his Ph.D. in biological sciences in 1988 from Carnegie Mellon, Pittsburgh, in the laboratory of Dr. Robert Murphy. He trained as a postdoctoral fellow and then as a research fellow at Stanford University from 1988 to 1999 in the laboratory of Dr. Leonard Herzenberg. Following this, he was adjunct associate professor, department of stomatology, University of California, San Francisco, until 2000, when he came to the VRC. He is a senior investigator and is chief of ITS, director of the Flow Cytometry Core, and director of the Nonhuman Primate Immunogenicity Core within the Laboratory of Immunology.
