Dr. Stevenson was also awarded the position of Elected Fellow in 2003 and 2004 for the American Academy of Microbiology and the American Association for the Advancement of Science, respectively. Dr. Stevenson’s research focuses on mechanisms of viral persistence as well as host factors that shape the interplay between the virus and host.

Lieping Chen, MD, PhD

Lieping Chen, MD, PhD
Yale University School of Medicine

Dr. Chen studies membrane proteins that control lymphocyte function and translates his laboratory findings to treat human disease. Dr. Chen performed the first proof-of-concept study in 1992 showing the B7-CD28 family molecules serve as targets for cancer immunotherapy by introducing B7-1 into tumor cells to enhance therapeutic immunity. This study inspired subsequent studies targeting the B7-CD28/CTLA-4 family molecules to treat cancer. Dr. Chen discovered B7-H1 (PD-L1) in 1999 and demonstrated PD-L1's role in immune evasion in the tumor microenvironment. He singularly established the PD-1/PD-L1 pathway as a target for cancer immunotherapy in 1999-2002. He also initiated and organized the first-in-man anti-PD-1 clinical trial to treat human cancer in 2006 and developed PD-L1 staining as a biomarker to predict treatment outcomes. His discoveries directly led to the development of anti-PD-1/PD-L1 antibody therapy against a broad spectrum of human cancers (first approved 2014, with five anti-PD-1/PD-L1 antibodies being FDA-approved since). Dr. Chen’s discoveries have revolutionized current oncology practices, treatments, and outcomes.

Dr. Chen’s laboratory has discovered numerous molecular pathways with immune modulatory functions, including 4-1BB (CD137), ICOS/B7-H2, B7-H3, B7-H4, B7-H5/CD28H, PD-1H (VISTA), LIGHT/HVEM, TROY, B7-H2/CD28/CTLA-4 (human), SALM5/HVEM. These discoveries have led to the development of therapeutic agents in various stages of clinical trials, treating various types of human cancer and autoimmune disease.

He has published over 350 research articles, reviews, and book chapters. His discovery work on the PD-1/PD-L1 pathway was cited as the #1 breakthrough of the year by Science magazine in 2013. He has received several professional recognitions, including the William B. Coley Award (2014), AAI-Steinman Award (2016), Shizhang Bei International Award (2017), Warren Alpert Foundation Prize (2017), Luminary Award (2018) and Giants of Cancer Care (2018).

Erling C. J. Norrby, MD, PhD
Center for History of Science, The Royal Swedish Academy of Sciences

Dr. Norrby is from the Karolinska Institute in the School of Medicine, Stockholm. He is a world authority on viruses and was Professor and Chairman at the Institute for 25 years. During this time he was President of the Division of Virology representing all the virologists of the world for three years. He has also served as the Dean of the Medical Faculty for six years and has been heavily involved in various ways for more than 20 years in the selection of the recipients of Nobel Prizes in Physiology or Medicine. He then left to become the Permanent Secretary of the Royal Swedish Academy of Sciences for six years.

Peter Palese, PhD
Icahn School of Medicine at Mount Sinai

Dr. Palese is Professor and Chair of the Department of Microbiology at the Icahn School of Medicine in New York. His research includes work on the replication of RNA-containing viruses with a special emphasis on influenza viruses, which are negative-strand RNA viruses. Specifically, he established the first genetic maps for influenza A, B and C viruses, identified the function of several viral genes, and defined the mechanism of neuraminidase inhibitors (which are now FDA-approved antivirals).

Dr. Palese also pioneered the field of reverse genetics for negative strand RNA viruses, which allows the introduction of site-specific mutations into the genomes of these viruses. This technique is crucial for the study of the structure/function relationships of viral genes, for investigation of viral pathogenicity, and for development and manufacture of novel vaccines. In addition, an improvement of the technique has been effectively used by him and his colleagues to reconstruct and study the pathogenicity of the highly virulent but extinct 1918 pandemic influenza virus. His recent work in collaboration with Dr. Garcia-Sastre has revealed that most negative strand RNA viruses possess proteins with interferon antagonist activity, enabling them to counteract the antiviral response of the infected host. Dr. Palese and colleagues are now aiming at developing a Universal Influenza Virus Vaccine, which is long-lasting and effective against all strains of influenza.

Dr. Palese is a member of the National Academy of Sciences, the National Academy of Medicine, and the American Academy of Arts and Sciences.

Jeffrey Schlom

Jeffrey Schlom, PhD
National Cancer Institute, NIH

Dr. Schlom is Chief of the Laboratory of Tumor Immunology and Biology, Center for Cancer Research at the National Cancer Institute, National Institutes of Health. He directs a translational research program focusing on the design and development of new cancer immunotherapies and immunotherapeutic strategies. The program takes advantage of the latest advances in genomics and immunology through hypothesis-generating preclinical research and translates these findings into paradigm-shifting science-based clinical trials.

Novel immunotherapies designed or developed in this program include therapeutic cancer vaccines, checkpoint inhibitors, immune modulators, and agents to inhibit immunosuppressive entities. Emphasis is placed on the development of "off the shelf" therapeutics that can be widely distributed and evaluated at multiple cancer research centers.

Dr. Schlom’s program has also developed a spectrum of immune assays that interrogates numerous components of the immune system, to help identify which patients will most likely benefit from immunotherapy either before treatment is initiated or early in the therapeutic regimen. Dr. Schlom serves on the editorial boards of numerous scientific journals, and has received numerous awards. He holds a wide range of patents in the area of immunotherapy and has authored more than 700 scientific publications.
