Biographical Sketch 
1973 PhD in Chemistry, California Institute of Technology (Caltech), Norman Davidson, advisor. She investigated genome organization of bacterial phages and bacterium using the heteroduplex-electron microscopy method. 1973-74, post doctoral training, UC San Francisco and Caltech. 1975, Fellow, Cold Spring Harbor Laboratory; 1976 Staff investigator; 1977 senior staff investigator; 1979, senior scientist with tenure. At CSHL, she continued to use heteroduplex-electron microscopy to study phage and viral genome organization and regulation as well as cellular gene structure. Her work led to the first discovery that DNA inversion regulates gene expression in the phage Mu system (Kamp et al., 1978). She was the lead author for the work reporting the discovery of mRNA splicing in adenovirus (Chow et al., 1977). This work was awarded the Nobel Prize in Physiology or Medicine in 1993 to her collaborator R.J. Roberts and P.A. Sharp of MIT. 1984-93, associate professor and professor of Biochemistry at University of Rochester. 1993-current, UAB.

Research/Clinical Interest
Title
Human papillomavirus DNA replication and pathogenesis
Description
My lab has been working on human papillomaviruses (HPV) for almost 2 decades. HPVs are prevalent and medically important human pathogens. The genome consists of a circular double-stranded DNA of 8 kbp. Infections by the mucosotropic HPV types cause anogenital condylomata and laryngeal papillomas. Infections by the high-risk HPVs can progress to dysplasia and cancinoma, notably, cervical, penile and anal cancers. Research in the lab spans the basic biology and pathobiology of these viruses. By examining patient specimens with in situ methods, we discovered that the productive phase of the virus infection takes place only in differentiated cells of a squamous epithelium. Thus, we develop organotypic cultures of primary human keratinocytes (PHKs) in which the cells stratify and differentiate into skin in vitro. Using this system, our lab produced HPV in vitro for the first time. By combining this culture system and retrovirus-mediated gene transfer, we have been investigating the functions of individual viral genes and the regulation of the viral promoters. We recently developed an efficient method to produce high titers of infectious HPV virus and recapitulated for the first time productive infections in PHK raft cultures. Using this new system, we are conducting genetic analysis of oncogeneic and non-oncogenic HPV typres. We also study the regulation of HPV DNA replication and the mechnaism of HPV DNA partitioning during cell division for persistent infection.
