Professional Bio: 

Dr. Campos earned his PhD from Rice University in 2005, studying the biology of adenoviral gene therapy vectors and vector targeting in the laboratory of Michael Barry now at Mayo Clinic in Rochester, MN. He then trained as a postdoc from 2005-2008 with Michelle Ozbun at the University of New Mexico, focusing on human papillomavirus (HPV) infection. He came to The University of Arizona in 2008 as an assistant research professor in the BIO5 Institute and joined the Department of Immunobiology as an assistant professor in 2011. 

Clinical Information

Clinical Focus: 

The high risk human papillomaviruses (HPVs) are the most prevalent sexually transmitted infections and are responsible for 5% of cancers worldwide. These oncogenic viruses establish persistent infections in the mucosal epithelium. Dr. Campos' broad interests are towards HPV-cell interactions and the biology of capsid structure, viral entry, trafficking, uncoating, membrane penetration, and the innate cellular responses to viral infection. Ultimately his work will not only identify potential target molecules and processes for development of prophylactic antiviral drugs and compounds, but it will broaden our fundamental understanding of HPV biology and viral mechanisms of immune evasion and persistence.
