Edward 'Eddy' Rubin

Principal Scientist


Eddy joins GV after spending nearly 14 years as Director of the Joint Genome Insitute of the US Dept. of Energy in Walnut Creek. Eddy provides scientifc leadership and guidance to the many ongoing projects at Global Viral. In 2002 he assumed the directorship of the DOE Joint Genome Institute (JGI) to lead the JGI’s involvement in the Human Genome Project (HGP). Under his leadership, the JGI completed the sequencing and analysis of human chromosomes 5, 16 and 19 (~13% of the human genome). After completion of the HGP, Dr. Rubin has led the reorientation of the JGI as a next-generation genome science center, applying genomics to studies related to bioenergy and the environment, sequencing and analyzing the genetic code of thousands of plants, fungi and microbes. In March 2016, Dr. Rubin stepped down as JGI Director. Dr. Rubin’s research has involved the development and application of computational and biological approaches for studying genomes. His early work focused on decoding the human genome. He then championed its functional exploration, harnessing sequence comparisons between species for the discovery of genes and non-coding sequences of pivotal evolutionary and biomedical importance. Other related work included sequencing and analysis of regions of the genomes of extinct cave bears and Neanderthals. More recently, he has expanded the frontiers of the new science of metagenomics, deriving important insights from his investigations of microbial communities inhabiting environments ranging from gutless ocean-dwelling worms to cow rumen. Dr. Rubin has published over 250 peer-reviewed manuscripts with more than 35 of them appearing in the journals Science andNature.


Eddy has a BA in Physics from University of California, San Diego, a MD from University of Rochester Medical Center, Rochester, NY, and a PhD in Biophysics from the University of Rochester, Rochester, NY. He received an Honorary Doctorate of Science Degree from Middlebury College, University of Rochester Dean’s Award, Netherlands Heart Association Declaration of Esteem, American Heart Association Established Investigator Award and has been inducted into the American Society of Clinical Investigation. He is a member of the Jackson Laboratory Board of Trustees, Genome Canada Board of Directors, Chair of the Scientific Advisory Board for the Genome Institute of Singapore, and serves on the scientific advisory boards of several additional biotechnology and research institutions.

Sarah Schlesinger

Sr. Attending Physician & Assoc. Professor of Clinical Investigation,

The Rockefeller University.

Dr. Schlesinger leads the clinical development of vaccines that target HIV and immunotherapies to treat other conditions, including cancer. Formally a member of the Steinman laboratory and now working with Michel C. Nussenzweig and Jeffrey V. Ravetch, she is interested in the clinical manipulation of the immune system’s dendritic cells to elicit immunity to diseases ranging from HIV to cancer. Although much research has been conducted in mice, the causes of human disease can differ considerably. Dr. Schlesinger is directing phase I clinical studies that employ the methods of immunology and dendritic cell biology, in which patients set the standards needed to understand diseases and treatments.

Dr. Schlesinger has been involved in the clinical trials of eight HIV vaccines and vaccine adjuvants. She is now conducting the first HIV vaccine trial based on dendritic cells, which were discovered at Rockefeller in 1973 by Ralph Steinman and his mentor, Zanvil Cohn.

In the steady state, dendritic cells capture antigens and travel to immune or lymphoid tissues, where they present to T cells, stimulating a robust immune response. But dendritic cells also play a seemingly opposite role, immune tolerance, which silences dangerous immune cells and prevents them from attacking the body’s own tissues. Working with Dr. Steinman, Dr. Schlesinger has used dendritic cells to study and design treatments that can harness the immune system, either to enhance or silence its functions, in an antigen- or disease-specific manner.

In addition to leading clinical trials, Dr. Schlesinger chairs the research education and training committee of the Center for Clinical and Translational Science at The Rockefeller University Hospital. She is also codirector of the Clinical Scholars program and the Certificate in Clinical and Translational Sciences program and is a member of The Rockefeller University Institutional Review Board.
