(Boston: October 1, 2025) – Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) today announced that Erin Duffy, Ph.D., Chief of Research & Development (R&D), has decided to depart the organization effective October 17, 2025. Dr. Duffy has served as CARB-X’s R&D lead since 2019, playing a pivotal role in advancing the global fight against drug-resistant bacterial infections.
During Dr. Duffy’s tenure, CARB-X strengthened its scientific strategy, expanded its global portfolio of innovative antibacterial products, enhanced its non-financial support model, and guided many dozens of projects through key stages of development. The CARB-X R&D team, under her leadership, added leaders in therapeutics, preventatives, and diagnostics to support product developers. CARB-X has also achieved significant milestones during Dr. Duffy’s time with CARB-X. As of September 2025, 20 products have advanced into or completed the first stage of human clinical trials, including 16 during her tenure – 13 of which remain active in human clinical trials, a testament to the productivity of the CARB-X R&D Team. In addition, she was instrumental in starting Investor Days to help connect product developers with industry partners that can help in funding later stage programs.
“Erin’s deep scientific insight and extensive global network of scientific and industry partners have been instrumental to CARB-X’s growth and success,” said Kevin Outterson, Executive Director of CARB-X. “Her leadership has advanced our mission to accelerate life-saving antibiotics and other products to address the global antimicrobial resistance crisis. We are deeply grateful for her contributions and wish her every success in her next chapter.”
Daniel Burgess, Chair of the CARB-X Joint Oversight Board, added, “Erin’s scientific excellence has strengthened CARB-X and advanced the field of antimicrobial innovation. I am grateful for her service and confident in the team’s ability to carry this vital mission forward.”
When sharing her decision to depart, Dr. Duffy expressed gratitude for her time at CARB-X, noting, “It has been a privilege to work with such a talented and dedicated team, and with funders, product developers, subject-matter experts, and partners, tackling one of the most urgent health threats of our time. I’m proud of the progress we’ve made together in accelerating innovation against antimicrobial resistance, and I am confident that CARB-X is well positioned to continue delivering transformative impact.”
CARB-X has initiated a search to identify the next Chief of R&D. In the interim, CARB-X leadership and the R&D team will ensure continuity of scientific and portfolio oversight. CARB-X remains committed to accelerating antibacterial innovation worldwide.
