Metabolomics/Lipidomics of bacteria:
This evolutionary biology project aims at elucidating why some bacteria make sterols
Research project funded by the National Science Foundation, NSF-IOS:
"Why do bacteria make sterols?", PI: N. Ward, co-PI: F. Basile
Our laboratory implements several MS techniques (GC-MS, GC-MS/MS, LC-ESI-MS/MS and LC offline MALDI-MS/MS) for the analysis of lipids, carbohydrates and metabolites in microorganisms. Recent work from our laboratory identified several hydroxy-fatty acids (some believed to be associated with lipid A) and polyunsaturated fatty acids in the microorganism Gemmata obscuriglobus. (Project in collaboration with Dr. Naomi Ward; Read the article in J. Bacteriology, 2016, 198, 221-236 journal link).

Microbial Proteomics:
A Study on Strategies for Forming Multicellular Organisms via Cell Aggregation
To form multicellular organisms via cell aggregation, cells must distinguish self from nonself to form a cooperative tissue. In this study, myxobacteria serve as model organisms for making these transitions. In this project we tested the role of the TraAB kin recognition system for a role in cell–cell cooperation because these cell surface receptors mediate the bidirectional exchange of proteins and lipids between cells. Strikingly, cells that adapted to environmental stresses shared their beneficial trait with naïve kin in a TraAB-dependent manner. Surprisingly, donor cells also benefited by apparently establishing harmony in the population when confronted with stress. We conclude that TraAB plays diverse roles in myxobacterial multicellular behaviors including their ability to cooperate.
