Visiting Grad Student

Susoma Jannat

Legionella pneumophila is a Gram-negative bacteria that can infect and replicate in alveolar macrophages, causing Legionnaires’ disease, severe pneumonia. One of the primary targets of bacterial pathogens appears to be the host ubiquitin-proteasome system. The Post-translational modification of proteins with ubiquitin is a highly regulated process that either targets proteins for degradation or modify their activity. Susoma’s research is to aim for the identification of E3 ligase effectors from pathogenic Legionella pneumophila through the protein molecular structure visualization by X-ray crystallography and NMR spectrometry with biochemical and in vivo/infection studies.

Peter Stogios

Protein and enzyme production and characterization

In biochemistry, “form” = “function”. 3D structure determination of proteins and enzymes is a powerful method for identifying and querying function such as identifying enzyme activity and substrate specificity, facilitating structure-based drug and inhibitor design, and guiding mutational analysis and biochemical characterization. Peter determines and characterizes the 3D structures of proteins produced by the Savchenko lab through Biozone’s x-ray diffraction facility and synchrotron partners, providing valuable functional interpretation and guidance for experimental follow-up.


Postdoctoral Fellow

Courtney Toth

Field Pilot Demonstration of Anaerobic BTEX Bioremediation Using Bioaugmentation Cultures

Benzene, toluene, ethylbenzene, and xylenes (BTEX) are widespread groundwater contaminants owing to accidental spills and releases of petroleum products into the environment. Though these pollutants can be metabolized by indigenous microbial communities, it is challenging to predict the extent of their degradation under anaerobic and site-specific conditions. Using highly-enriched BTEX-degrading cultures and biomarker tools, Courtney’s research aims to test bioaugmentation as a prospective remediation biotechnology. The goal of this project is to significantly decrease time and costs associated with clean up of BTEX pollutants. She is also interested in the molecular characterization of anaerobic benzene biodegradation.
