Summary: This application is for an administrative supplement to enhance diversity in health-related research under the aims of the parent grant, “Physiology of bacterial metabolism in the human gut microbiome” (GM142873). The supplemental funds will provide support for Dr. Michelle Miranda-Velez, a post-doctoral scholar in the PI’s laboratory. Dr. Miranda-Velez has extensive expertise in chemistry, synthesizing polymers with biological activity against Mycobacteria. The current supplement will provide a rigorous research training experience for Dr. Miranda-Velez in the biochemistry and physiology of the human gut microbiota. In addition, it will provide an individualized mentorship and career development plan designed to support Dr. Miranda-Velez as she follows her chosen career path to start her own independent research group at a US academic institution. While advancing the NIH mission for enhancing diversity, the proposed supplement will also enhance the goals of the parent grant.
