Title: Overcoming antibiotics of last resort: determining the role of compensatory mutations in promoting vancomycin resistance in Staphylococcus aureus
The rise of antimicrobial resistance has left clinicians with few options for the successful treatment of many microbial pathogens, which has resulted in an increasing reliance on antibiotics of last resort. In isolated cases, pathogens have acquired resistance to an antibiotic of last resort yet have not managed to spread among patients. This project investigates the genetic basis for why one such resistant pathogen, vancomycin resistant Staphylococcus aureus (VRSA), has never spread between patients, with the goal of developing a better understanding of the barriers that can prevent epidemics of antimicrobial resistance from emerging.

Title: Uncovering synergistic antibiotic cocktails with comparative genomics
The rapid evolution and spread of antimicrobial resistance among microbial pathogens has dire consequences for human health. To develop strategies for mitigating the rise of resistance, we will use comparative genomics to study the evolution of antibiotics in naturally antibiotic-producing microorganisms. Our work has many expected positive outcomes, including: 1) discovering new antibiotics for drug development, and 2) revealing strategies for combating the rise of resistance.

Title: Illuminating emergent properties underlying complex carbon degradation within communities of soil microorganisms
Soil microorganisms play a key role in the global carbon cycle by degrading the complex carbon molecules comprising plant litter and cell detritus. This provides a critical ecosystem service by returning carbon to the atmosphere in the form of CO2. Carbon degradation is a complex process believed to require the contributions of multiple different soil microorganisms. Despite their importance, we still know relatively little about how soil microbial communities assemble on complex carbon sources. Here, we seek to identify the set of small molecules that govern community assembly and the collective degradation of complex carbon molecules.

Title: Decrypting inter-cellular communication within the soil microbiome by eavesdropping on pairwise signaling between bacteria
The soil microbiome is composed of a dense network of interacting cells that play a pivotal role in nutrient cycling and plant growth. Decrypting how soil microorganisms communicate through a wide variety of small molecules is essential for understanding their functional roles and ecological dynamics. We have previously developed and characterized a 3D printed platform for eavesdropping on interactions between pairs of bacteria. Using advanced mass spectrometry resources at EMSL, we can apply this platform in high-throughput to infer the context-specific language of microbial communication for a large panel of soil bacteria. In particular, we seek to tease apart individual contributions to the immense signaling network within the soil microbiome. This will enable us to elucidate higher-order principles of inter-cellular communication, with the ultimate goals of manipulating the soil microbiome to improve nutrient management, identifying novel strategies in microbial competition, and controlling plant-microbe interactions in the rhizosphere.
