My main statistical methods research interests are concentrated on developing methods for analysis of infectious disease data and methods for analysis of data with missing values. Recently I worked on developing methodology to estimate breastmilk infectivity among HIV-1 infected mothers, and continue to collaborate on the development of survival analysis methods when the outcome variable is measured with uncertainty.
The majority of my collaborative work has been in HIV-1 prevention studies. I have been involved in studies investigating transmission of HIV-1 through breastfeeding, including serving as lead statistician of a randomized clinical trial to determine the frequency and timing of breastmilk transmission. Additional collaboration on this study has led to analyses determining correlates of genital and breastmilk shedding of HIV-1 DNA, and investigating the effects of breastfeeding on disease progression of HIV-1 infected mothers. I was also involved in a large cohort study with the primary aim of determining whether cytotoxic T lymphocytes in HIV-uninfected exposed infants have a role in protecting against breastmilk transmission of HIV-1. I also was a member of an international working group researching epidemiological, biostatistical, and clinical issues in mother-to-child transmission of HIV-1 (The Ghent Group)
As an investigator at the Statistical Center for HIV/AIDS Research and Prevention (SCHARP) at The Fred Hutchinson Cancer Research Center, I am involved as lead statistician on a variety of studies of microbicides as preventive agents for sexual transmission of HIV-1 - including HPTN 035. In this role I collaborate on protocol teams and provide expertise in study design and other aspects of study development, conduct, and analysis.
I served as the principal investigator (PI) for the statistical coordinating center for the NICHD sponsored HC-HIV study (based at SCHARP). This was a prospective cohort study of over 6,000 women in Thailand, Uganda, and Zimbabwe family planning clinics. The primary aim of the study was to determine if the use of hormonal contraception by HIV-1 uninfected women increases their risk of acquiring HIV-1. I currently serve as the co-PI for the statistical coordinating center for the NIH funded Microbicides Trials Network (MTN).
