Robert (Bob) Danczak studies the dynamics of natural organic matter across ecosystem types, integrates microbiological and natural organic matter data, and develops novel ecological tools for the Subsurface Research project. He has extensive research expertise in microbial ecology, metagenomics, bioinformatics, cheminformatics, and biogeochemistry. 

• Evaluating the ecological processes that impact microbial communities within and across scales.
• Combining various omics techniques to derive new understanding of biogeochemical processes.
• Applying ecological theory to better understand how assemblages of molecular formulas develop in natural environments.

• PhD in Microbiology, The Ohio State University, 2018
• BA in Biology and Biochemistry, Hiram College, 2013

• Outstanding Performance Award, Earth and Biological Sciences Directorate, PNNL (2020)
