Research Overview

Dr. Brown’s Lab at Texas Tech University focuses on the evolution, ecology, and function of host-associated microbes  — especially those involved in beneficial interactions — using a range of “omics” approaches, including shotgun metagenomics, metatranscriptomics, proteomics, etc. Systems include symbiotic bacteria and fungi living on or in insects, nematodes, plants, and other hosts. In 2021, Dr. Brown received a joint National Science Foundation CAREER/ U.S. Department of Agriculture grant to study how bacteria affect nematodes.
