Dr. Gravitt's research interests are primarily focused on the molecular epidemiology and detection/screening for human papillomaviruses and cervical cancer. She has developed and validated gold standard PCR-based methods for the detection and quantitation of human papillomaviruses. Recent work has been dedicated to understanding the role of HPV viral load in the progression of cervical neoplasia and understanding other biologic and environmental factors that influence detectable viral load in women without evidence of cervical disease.

Dr. Gravitt's current research agenda includes evaluation of cervical cancer screening strategies in rural India, evaluation of inflammatory biomarkers in STI clinic populations, and methodologic issues of misclassification of laboratory derived exposure measures.
