Samuel K Campos, PhD
Asociate Professor, Immunobiology
Sam earned his Ph.D. 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. Sam 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. Sam was promoted to Associate Professor with tenure in Spring 2017.
Persistent infections by the high-risk human papillomaviruses (HPVs) cause 5% of total cancers worldwide, including essentially all of the cervical cancers in women. The overall goal of our research is to understand the molecular mechanisms through which HPVs infect and attain persistence in host epithelium. Knowledge of these mechanisms will broaden our understanding of viral-host interactions, may unveil new aspects of cell biology, and could identify potential targets for therapeutic or prophylactic intervention to prevent HPV infections and their associated cancers.
