Dr. Roman-Reyna is an Assistant Professor in the Plant Pathology and Environmental Microbiology Department. She wants to integrate several -omics tools ("Veromics") in her research program to understand, at different scales, the pathogen changes associated with the host and environment adaptation.

Her research training is truly global. She worked in four countries in collaborative, culturally diverse research teams. She did her BSc and MSc in Colombia, her Ph.D. in Australia, and her post-docs in The Philippines and the United States. She has always focused her research on important crops such as cassava, potato, oil palm, rice, wheat, and barley.

Some of her current research projects are related to Potato soft rot and blackleg in Pennsylvania, Metagenomics for plant pathogen diagnostics, and Bacterial rice diseases.
