IAS - the International AIDS Society

IAS – the International AIDS Society – leads collective action on every front of the global HIV response through its membership base, scientific authority and convening power.

Founded in 1988, the IAS is the world’s largest association of HIV professionals, with members in more than 170 countries. Working with its members, the IAS advocates and drives urgent action to reduce the impact of HIV. The IAS is also the steward of the world’s most prestigious HIV conferences: the International AIDS Conference, the IAS Conference on HIV Science, and the HIV Research for Prevention Conference. In light of the SARS-CoV-2 pandemic, IAS also convened two abstract driven COVID-19 conferences, in July 2020 and February 2021.

Chancellor Angela Merkel, Germany

Angela Merkel was born in Hamburg on 17 July 1954, but spent most of her childhood in Templin, in Brandenburg, East Germany. After reading physics at Leipzig University (1973 1978), she conducted research into quantum chemistry at the Central Institute of Physical Chemistry at the Academy of Sciences in Berlin. She obtained her doctorate in 1986 with a thesis on calculating the velocity constants for simple hydrocarbon reactions.

In late 1989, Angela Merkel joined “Demokratischer Aufbruch” (Democratic New Beginning). She soon became their Press Spokeswoman and then, following the first free elections to the People’s Chamber of the then GDR on 18 March 1990, she was appointed Deputy Government Spokeswoman for Lothar de Maizière’s Government. She has been a member of the CDU (Christian Democratic Union of Germany) since August 1990, and a member of the German Bundestag, for the constituency of Stralsund, North Western Pomerania and Rügen, since December 1990. From 1991 to 1994 she served as Federal Minister for Women and Youth, subsequently becoming Federal Minister for the Environment, Nature Conservation and Nuclear Safety, a position she held until 1998.

From December 1991 until her election as General Secretary of the CDU on 7 November 1998, she held the post of Deputy Chairwoman of the CDU in Germany. She was simultaneously Chairwoman of the Mecklenburg-Western Pomerania CDU from May 1993 to May 2000. She has been Chairwoman of the CDU in Germany from April 2000 to December 2018. She also served as Chairwoman of the CDU/CSU Parliamentary Group in the German Bundestag from September 2002 until she was first elected as Chancellor in November 2005.

Hendrik Streeck, Germany

Professor Hendrik Streeck is the Director of the Institute of Virology and Professor of HIV Research at the University of Bonn, Germany. He completed his medical training in Berlin in 2006 and received his PhD from Friedrich-Wilhelm University in Bonn in 2007. After completing his postdoctoral fellowship at the Partners AIDS Research Center, he was Assistant Professor at the Ragon Institute of MGH, MIT and Harvard and assistant immunologist at the Massachusetts General Hospital. In 2012, he was recruited as the Chief of the Cellular Immunology Section of the U.S. Military HIV Research Program and adjunct Assistant Professor of Emerging Infectious Diseases at the Uniformed Services University of the Health Sciences. In March 2015, he took the chair of the Institute for HIV Research, but remains visiting scientist at the Military HIV Research Program on HIV vaccine and cure research. Currently, he leads the largest systematic study to understand the feasibility of conducting a Phase 3 HIV vaccine trial in Europe and to understand the epidemic of sexually transmitted infections. As a result of the study, the European HIV & STI prevention network was established in January 2019.

Anthony S. Fauci, United States

Anthony S. Fauci, M.D., is director of the National Institute of Allergy and Infectious Diseases (NIAID) at the U.S. National Institutes of Health, where he oversees an extensive research portfolio devoted to preventing, diagnosing, and treating infectious and immune-mediated diseases. Dr. Fauci has been a key advisor to six Presidents and their administrations on global AIDS issues, and on initiatives to bolster medical and public health preparedness against emerging infectious disease threats such as pandemic influenza. As an HIV/AIDS researcher he has been involved in the scientific effort since AIDS was recognized in 1981, conducting pivotal studies that underpin the current understanding of the disease and efforts to develop therapies and tools of prevention. Dr. Fauci was one of the principal architects of the President’s Emergency Plan for AIDS Relief (PEPFAR), which has helped save millions of lives throughout the developing world.

Dr. Fauci is the long-time chief of the NIAID Laboratory of Immunoregulation. He has made many contributions to basic and clinical research on the pathogenesis and treatment of immune-mediated and infectious diseases. He helped pioneer the field of human immunoregulation by making important basic scientific observations that underpin the current understanding of the regulation of the human immune response. In addition, Dr. Fauci is widely recognized for delineating the precise mechanisms whereby immunosuppressive agents modulate the human immune response. He developed effective therapies for formerly fatal inflammatory and immune-mediated diseases such as polyarteritis nodosa, granulomatosis with polyangiitis (formerly Wegener’s granulomatosis), and lymphomatoid granulomatosis.

Dr. Fauci has made seminal contributions to the understanding of how HIV destroys the body’s defenses leading to its susceptibility to deadly infections. Further, he has been instrumental in developing highly effective strategies for the therapy of patients living with HIV/AIDS, as well as for a vaccine to prevent HIV infection. He continues to devote much of his research time to identifying the nature of the immunopathogenic mechanisms of HIV infection and the scope of the body’s immune responses to HIV.

Dr. Fauci is a member of the US National Academy of Sciences and the US National Academy of Medicine, and is the recipient of numerous prestigious awards for his scientific and global health accomplishments, including the National Medal of Science, the Robert Koch Medal, the Mary Woodard Lasker Award for Public Service, the Prince Mahidol Prize, The Gairdner Canada Award for Global Health, and the Presidential Medal of Freedom. He has been awarded 45 honorary doctoral degrees and is the author, coauthor, or editor of more than 1,300 scientific publications, including several major textbooks

Danny Douek, United States

He was appointed to the NIH Vaccine Research Center in November 2000.

His laboratory, the Human Immunology Section, studies the processes that determine the course of human diseases in which the immune system, particularly its T-cell arm, plays a central role in their pathogenesis and outcome. He aims to use the knowledge gained to initiate clinical studies of new therapeutic and vaccine approaches.

Dr Douek is widely published in the field of human immunology, having made significant discoveries in thymic function, immune repertoire diversity, T-cell mediated immunity, mucosal immunology, innate immunity and hematopoietic progenitor cell transplantation. He has published more than 300 papers, has an h-index of 100 and is among the 1% most cited scientists in their field. Currently, the main focus of his lab is the pathogenesis of HIV infection, the role of the microbiome in modulating systemic inflammation, and host genetic factors that predispose to or protect from infectious disease.

He sits on numerous scientific advisory boards and journal editorial boards. Dr Douek received the World AIDS Day Award in 2007 and the NIH Director’s Award in 2008. Scientific American recognized him as one of the world’s top 50 scientists in 2005 and he was placed among the 2012 POZ 100 for his significant contributions to accelerating the end of AIDS.
