Claudia K. Gunsch

Theodore Kennedy Associate Professor

Dr. Gunsch’s research focuses characterizing and engineering environmental microbiomes.  Students and postdoctoral associates in her group apply fundamental concepts from the fields of microbiology, genomics and bioinformatics to environmental engineering applications. Current research projects focus on exploring ballast water microbiomes, exploring correlations between microbial adaptation and evolution stemming from their exposure to contaminants, characterizing the fate of genetically modified crop transgenes, developing genetic bioaugmentation technologies for improving the bioremediation efficacy of recalcitrant contaminants and developing innovative water treatment technologies for industrial and developing world applications.
