Areas of clinical research interest

       Herpesviruses: My primary role is to provide statistical support to herpes research taking place at the Virology Research Clinic. We conduct observational studies examining the natural history of HSV in a wide variety of patient groups, e.g. men and women, HIV positive and negative, homosexual and heterosexual. We also evaluate transmission of HSV at birth from mother to infant, and participate in studies of candidate HSV vaccines and treatments.

        HIV: I have also contributed to clinical trials of HIV prevention as part of the Partners in Prevention study team, now known as the UW International Clinical Research Center.



Areas of statistical research interest

          Methods of assessing viral shedding: I have authored original work on

o   optimizing detection, (Magaret AS, Wald A, et al. 2007. Optimizing PCR positivity criterion for detection of HSV DNA on skin and mucosa. Journal of Clinical Microbiology;45(5): 1618-20.)

o   quantification, (Magaret AS, Johnston C, et al. 2009. Use of the designation "shedder" in mucosal detection of herpes simplex virus DNA involving repeated sampling. Sexually Transmitted Infections;85(4):270-5.)

o   optimal study design, (Magaret AS, Stanaway J. 2011. Sample size for a binomial proportion with autocorrelation. Stat Comm Infect Dis;3(1):Article 8. DOI: 10.2202/1948-4690.1036.)

o   optimal regression approach for crossover studies, (Magaret AS, Models for HSV shedding must account for two levels of overdispersion. University of Washington Biostatistics working paper series, #410.
