Biography

Dr. Lehmann’s research tackles the global crisis of antibiotic resistance. Since the discovery of antibiotics in the early to mid-20th century, bacteria have rapidly evolved mechanisms to resist their effects. This loss of efficacy in once-groundbreaking antibiotics, coupled with the emergence of resistant strains, has led to a troubling increase in infections and deaths caused by drug-resistant pathogens. Dr. Lehmann's work focuses on alternative strategies informed by the growing understanding of the human microbiome. Long before antibiotics were used, beneficial bacteria in the microbiome played a critical role in maintaining health by competing with and suppressing harmful microbes. However, antibiotic use disrupts this balance, allowing drug-resistant pathogens to thrive. In response, Dr. Lehmann is developing approaches to restore and protect beneficial components of the microbiome. By promoting a healthy and resilient microbiome, his research aims to prevent infections, reduce reliance on traditional antibiotics, and provide powerful new avenues to combat antibiotic-resistant diseases.
