Dr. Lahmers aims to improve animal and human health by better controlling infectious diseases in food animals. He focuses on potential zoonotic diseases caused by Escherichia coli O157:H7, as well as Salmonella, and Mycobacterium avium subsp. paratuberculosis, which causes intractable gastrointestinal disease in cattle and has been associated with Crohn's disease in humans.
He focuses on the molecular and cellular mechanisms of immunity to infectious disease, with special emphasis on mucosal immune responses. His work strives to explore and expand new approaches to vaccine development. He also examines the nonclassical immune response and innate immunity in order to develop new strategies for combating disease.
Dr. Lahmers is a diplomate of the American College of Veterinary Pathologists and uses his pathology training in work in the Washington Animal Disease Diagnostic Laboratory as well in his research efforts. He is an assistant professor in the Department of Veterinary Microbiology and Pathology and the Paul G. Allen School for Global Animal Health.
