My research focuses on developing new software and computational methods to advance agriculture by understanding and controlling microbial communities and applying artificial intelligence and machine learning to agricultural data.

Research areas

• Applying machine learning to agricultural data (sequence, image, and chemometric data)
• Engineering and optimizing microbial consortia
• Developing software (e.g. Itsxpress, Guidemaker) for bioinformatics
• Applying volatiles mass spectrometry and machine learning to agricultural challenges
• Viral metagenomics

Service areas

• Design and sequencing of amplicon, metagenome, and metatranscriptome experiments
• The development of training courses for ARS, like our 2019 UF/ARS Machine learning Workshop
• Guiding SCINet ARS’s scientific computing initiative as Chair of the SCINet Advisory Committee
• Establishing the ARS AI Center of Excellence in collaboration with our Associate Administrator and Chief Scientific information officer
• Editorial board for the journal ACS Agriculture Science and Technology
