In 2015, he was selected to be on the list of the TIME 100 Most Influential People in the world, He served on the Advisory Council of the National Center for Complementary and Integrative Health (NCCIH) of the National Institutes of Health from 2015-2019. He was appointed by President Obama as the Chair of the President's Advisory Council on Combating Antibiotic-Resistant Bacteria (PACCARB) for a term from 2015–2022, serving in the Obama, Trump, and Biden administrations. In 2019, he founded the Rutgers University Microbiome Program (RUMP), which is a university-wide project to develop microbiome science, and examine its impact on health, agriculture, the environment, and human culture. He now co-leads RUMP with Rutgers professors Maria Gloria Dominguez Bello and Liping Zhao. Blaser sits on scientific advisory boards for Elysium Health, Procter & Gamble, Dupont, and several biotechnology start-up companies. In June 2018, Blaser joined the Scientific Advisory Board of the newly founded Seed. In December 2020, he became the chair of start-up Micronoma's scientific advisory board. He serves as Co-Chair of the Advisory Board of Humans and Microbiome program off the Canadian Institute for Advanced Research (CIFAR) a In 2019 he received the Robert-Koch-Medal in Gold, and the Karl August Mobius Fellowship from Kiel Life Sciences. In 2021, he received the Prize Medal from the Microbiology Society (UK), for his studies of the human microbiome including Helicobacter pylori as an agent of disease in humans.In 2022, he received an honorary doctoral degree from the University of Bordeaux (Docteur honoris causa) Research Blaser is best known for his studies of Helicobacter pylori and its relationship with human diseases. Initially dismissive and skeptical of Nobel laureate Barry Marshall's findings of H. Pylori's relationship to gastric and peptic ulcers, which Blaser described as "the most preposterous thing I’d ever heard; I thought, this guy is a madman,” Blaser's work nonetheless later helped establish the role of H. pylori in the causation of gastric cancer, the second leading cause of cancer death in the world. Studies of the diversity of H. pylori lead him to identify the CagA protein and its gene in 1989, which broadened understanding of H. pylori interactions with humans. His team found that cagA+ strains induced enhanced host responses, development of atrophic gastritis, gastric cancer, and peptic ulcer disease, compared to cagA− strains,
