Scientific Focus
Current Research Interests
Clinical research focused on the diagnosis, prevention and treatment of anal cancer and its precursor lesions. Clinical trials of ablative therapy for High-grade Squamous Intraepithelial Lesions (HSIL) of the anus and perianal tissues as a means for preventing anal cancer.
Basic science work in collaboration with Ronald Davis and Hanlee Ji focused on the molecular genetic and pathologic studies of anal cancers using moecular inversion probe genomic technology
