OverviewAI-generated summary

Dr. William W. Greenfield's research focuses on human papillomavirus (HPV) infections, particularly in relation to cervical intraepithelial neoplasia (CIN) and cervical cancer. His work has investigated the evaluation of DNA extraction protocols from cytology specimens for studying cervical microbiota and has explored therapeutic vaccine approaches, such as the peptide-based HPV therapeutic vaccine PepCan, in clinical trials for treating CIN2/3. He has also examined the immune responses generated by these therapeutic interventions. Dr. Greenfield's research interests extend to maternal health, including the assessment of public maternal health dashboards in the United States and personal birth experiences among labor and delivery staff. His background includes a pharmacy degree from Auburn University and extensive training in obstetrics and gynecology, including da Vinci Robotic Surgery.
