Characterizing T cells induced by candidate vaccines using flow cytometry. Developing new assays to evaluate vaccine efficacy with HIV Vaccine Trials Network. Studies include examining T cell function at the single-cell level using advanced flow cytometric techniques; examples include T cell responses to vaccination and to viral infections such as CMV, EBV, HIV, and hepatitis B.
Statistical and computational methods for bioinformatics applications, statistical modeling for genome sequence analysis and statistical modeling frameworks. The interface between computer science, statistics, and molecular biologyand such as development of new informatics methods in genomics and post-genomics

Determining how changes in microbial communities impact human health; identifying, characterizing, and culturing microbes found in the human genital tract; and associating the reproductive tract microbiome with human disease.
Developing molecular diagnostic tests to detect and identify pathogens in immunocompromised hosts such as cancer patients.
Research focus includes vaccine clinical trials, the design and analysis of Phase I/II trials, for evaluating vaccine effects on immune responses; the design and analysis of Phase 2b/III trials, for evaluating vaccine efficacy, immune correlates, sieve analysis, and post-infection vaccine effects; general biostatistical methods research, such as survival analysis, causal inference, and evaluation of surrogate endpoints

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
