Jason R. Rohr
Dr. Rohr is an associate professor in USF’s Integrative Biology Department. He uses a transdisciplinary approach to evaluate how natural and anthropogenic stressors affect wildlife populations, species interactions, and the spread of disease. He is using genomic studies to assess how biodiversity, synthetic chemicals, and host immune responses mediate infectious disease risk. His lab has used 16S-sequencing to determine how exposure to pesticides and antibiotics disrupt the biodiversity of host microbiomes and is now focusing on transcriptomic approaches and functional immune assays to determine how the microbiome will affect pathogen defense.
