Statistical support to clinical research on HSV1 and HSV2 and other herpesvirus infections; Clinical association between herpes and HIV; statistical methods work in areas such as misclassification in time-to-event outcomes, laboratory assay validation, and methods for quantifying and examining risk factors for viral shedding
Natural Killer Cell Receptor Diversity and CMV in Hematopoietic Cell Transplantation; Viral infections after Hematopoietic Stem Cell Transplantation; Epidemiology of invasive Fungal infections in Cord Blood Transplant Recipients and Clinical trials of the prevention of post-transplant infection
Interest in describing the quantitative and dynamical features of human pathogens and immune responses. Most of work to-date is on the pathogenesis of HSV-2 infection but also interested in applying models to optimize viral eradication startegies, and to use models to capture kinetic features of the human microbiome.
Research is focused on longitudinal data analysis, survival time models, cancer prevention and screening trials, HIV vaccine evaluation; design, coordination, and analysis of clinical trial programs to evaluate promising candidate vaccines for globally important infectious diseases; analyses of immune response and viral genomic data to improve partly-efficacious vaccines
Research is focused on the development of a safe and effective vaccine to combat the spread of HIV and to investigate how HIV infection leads to AIDS. Two major areas of research is to better understand how neutralizing antibodies against HIV are developed during natural HIV-infection,and engineer immunogens that will elicit broadly neutralizing antibody responses against HIV.
Research interests involve mechanisms driving the differentiation of B cells following vaccination and infection, understanding how differences in the pre-immune repertoire influences immunity and vaccine Development
