Jacqueline Mejia Awarded DOE SCGSR Fellowship

Doctoral candidate Jacqueline Mejia was awarded a fellowship from the DOE Office of Science Graduate Student Research to work with Professor Jack Gilbert at Argonne National Laboratory and the University of Chicago.


Jackie’s project will use model Fe oxide-SOM (denoted Fe-SOM) complexes to study how the chemical nature of SOM and its interaction with Fe oxides shapes SOM metabolism under environmentally relevant conditions. A comparative metagenomic analysis of the communities that arise in these experiments will provide insight into the microbial community structure and the metabolic pathways involved SOM mineralization. Moreover, the information obtained from this study has the potential to improve metabolic models utilized to predict the fate of C in soils and sediments.
