Jose Pablo Soto-Arias

Jose Pablo Soto-Arias is a PhD student working under the guidance of Dr. Jeri Barak and Dr. Russell Groves studying the role of phytophagous insects in the multiplication and persistence of Salmonella enterica on plants. The ultimate goal of my research is to reduce the incidence of food-borne illness and provide a safer food supply through a better understanding of the mechanisms that allow these bacteria to grow in the phyllosphere following phytophagous insect infestation. His main interests are vector-pathogen-host interactions, plant/human bacterial pathogens, food safety and global food security.

This project was recently highlighted in the Fall 2014 Issue of Grow.
