Dr. Anthony Bertagnolli is a Senior Research Scientist in Dr. Frank Stewart’s research group at Montana State University. He investigates the diversity, activity, and abundance of microorganisms involved in methane and ammonia oxidation, as well as nitrate and sulfate reduction, a in a variety of terrestrial and marine environments along gradients of oxygen availability. To understand these populations, Dr. Bertagnolli applies a combination of culture independent molecular approaches, culture dependent enrichment approaches, and process-based rate estimates to water-column, sediment and soil samples. His current projects include investigation of riparian, surface water, and aquifer environments where microbial activity interacts strongly with water quality, particularly the abundance and fate of nitrate and sulfate.
