About Us

Dr. Prenni received her Ph.D. in Analytical Chemistry from the University of Colorado, Boulder followed by post-doctoral training at the Scripps Research Institute in La Jolla, California. She served for over ten years at the Director of the Proteomics and Metabolomics Core Facility, now the ARC-BIO, at Colorado State University. During this time, her group developed novel approaches in metabolomics for analytical methods and data analysis including the RAMClustR algorithm, developed by Dr. Corey Broeckling, for metabolite clustering and annotation. Presently, Dr. Prenni is an Associate Professor in the Department of Horticulture and Landscape Architecture in the College of Agricultural Sciences at CSU where the overall theme of her research is the application of mass spectrometry to address important issues in food/crop safety and quality.

The major research themes of the Prenni laboratory include:

(1)  Non-targeted and targeted metabolite profiling of plant tissue and exudates to dissect complex genotype by environment (G x E) interactions, including the microbiome.

(2) Development of novel approaches using ambient ionization for characterization of food quality and authenticity.

(3) Sensitive and rapid quantification of drug and chemical residues in food products.

(4) Novel method development for metabolomics sample preparation, data acquisition, and informatics.
