Haig Alexander Eskandarian is a microbiologist and infectious disease expert working as a researcher at the University of California, San Francisco, in the United States. Haig holds a bachelor’s degree in biochemistry and molecular biology from the University of Richmond, a master’s degree in developmental biology from New York University, and a PhD in microbiology and cell biology from the Université Paris Descartes, while working at Institut Pasteur. He was an EMBO advanced long-term fellow at the École Polytechnique Fédérale de Lausanne, in Switzerland, where he developed Long-Term Time-Lapse Atomic Force Microscopy as a novel imaging modality to study bacterial individuality. Haig is keenly interested to understand why individual bacteria tolerate antibiotic treatments despite harboring genetic susceptibilities resulting in prolonged infection. Haig has equally been active, since 2011, in organizing and teaching advanced lecture and practical courses in biology (host-pathogen interactions), in Yerevan. He is dedicated to developing science education and fundamental research in Armenia
