NIAMRRE Scientists are faculty, staff, and educators at NIAMRRE member institutions actively working in AMR. Being designated as a NIAMRRE Scientist aids us in connecting people to organizations and projects that will advance our understanding of AMR. NIAMRRE Scientists are integral to building the NIAMRRE community. As we add new members, our community will expand.
