Diana is passionate about microbiology research and states that a better understanding of bacterial interactions can lead to better interventions and an improvement of food safety and public health.

Diana joined Purina Animal Nutrition in 2019 as a microbiologist senior scientist for research and development, where her main focuses are the development of interventions that could replace the subtherapeutic use of antibiotics and the use of next-generation sequencing technologies to study the effect of feed additives on gut’s microbiome, their influence on immune response, and efficacy at reducing bacterial pathogens’ intestinal colonization.

Diana holds a master’s in food science and Ph.D. in animal science, with a focus on molecular microbiology, from Texas Tech University. Prior to joining Purina, she worked as a post-doctoral research associate developing strain-specific direct fed microbial (DFM) detection and quantification assays and the study of microbiome of animals fed a DFM-supplemented diet.
