Research interests include sexual risk taking, victimization and alcohol/drug abuse among African-American women, HIV prevention for African American and African-born populations and health disparities.
Mathematical modeling of virus and immune system dynamics. Population/within-host dynamics approach to quantify HIV-1 infection and treatment efficacy (ordinary differential equations, nonlinear mixed effects models).
Research interests include mathematical modeling of infectious diseases, evaluating impact of interventions for HIV prevention, mathematical biology (population dynamics, epidemic modeling) and dynamical systems (ODE, PDE, and impulsive systems)
Oversight for quality control of Good Clinical Lab Practice (GCLP)-compliant assays and is studying cellular immune responses to HIV vaccines for the Cape Town HVTN laboratory. Research involves interrogation of the phenotype and transcriptional profile of vaccine induced T cells in order to better understand these T cell responses.
Computational and statistical methods development for high-throughput, high-content biological data.
Modeling and integration of data from high throughput assays for biomarker discovery, clinical outcome prediction and disease classification.
Current studies include development of methods for T-cell based sieve analysis, quantification of vaccine induced T cell responses, systems biology of influenza and time-dependent correlates analysis of HIV efficacy trial.
Clinical and translational investigations relating to infections in immunocompromised hosts, with a focus on disease associations, risk stratification, and diagnostic strategies for viral infections in transplant recipients
Immunologic endpoint determination for experimental vaccines (HIV, pneumococcus, malaria, TB, flu) and
Logistics, operations, quality assurance, and assay validation for immunologic evaluation of vaccines in the clinical trial setting
Design and analysis of vaccine efficacy trials, genotype-specific vaccine efficacy-based sieve analysis,immune correlates of vaccine protection, analysis of vaccine-induced immune response durability and survival analysis
HIV vaccine development and trial design, combination HIV prevention, mucosal immunology and mucosal sampling design in HIV prevention trials, the intersection of oncology and infectious disease, comparative effectiveness, decision analysis and health-related quality of life
Research interests involved developing and implementing clinical trials for HIV vaccines, mucosal sampling in HIV Vaccine trials and cultural/community challenges in implementing Vaccine Trials in Africa
Research focus includes preclinical animal models for vaccines and adjuvants testing, vaccine product development and clinical trial design, vaccine adjuvants, formulations and innate immune responses, immunological evaluation of vaccines and project management for collaborative research projects
Epidemiologic studies of infectious disease transmission, vaccine studies and the development of novel statistical methods and designs for studies of infectious disease transmission. Efficacy and effectiveness assessments of control and prevention strategies for infectious diseases of import to global health, including influenza, cholera, dengue, and tuberculosis
