Research Summary

Dr D'Souza's primary research interest is in infectious causes of cancer. Current research explores the association between Human Papillomavirus (HPV) and oral, cervical and anal cancers, the natural history and concordance of oral and anogenital HPV infection, and HPV tropism.

Dr. D'Souza also has active research programs evaluating cancer screening methods and potential biomarkers. Additional interests include the role of behavioral factors on viral acquisition and persistence, epidemiology of sexually transmitted infections, the effect of viral load and drug use on disease progression, the epidemiology of HIV/AIDS, and infectious causes of AIDS malignancy.
