项目摘要
Project Summary
Candidate: Dr Sikhulile Moyo is unwaveringly committed to an overarching career focused on contributing to
ending the HIV epidemic and related public health emergencies. He committed to a career focused on finding
cost-effective tools for estimating the impact of interventions and towards HIV cure research. He envisions
himself as a leader globally, in research aimed towards tracking and eliminating new HIV infections & towards
developing an HIV cure, working with researchers, program implementers and policy makers for rapid and
cost-effective evaluation of interventions. Dr Moyo’s 5-year career development plan is focused on three key
areas: phylogenetics, epidemiology and biostatistics; cross-sectional Incidence and Implementation; and HIV
cure & characterization of early founder viruses, and SARS-COV-2 genomics. In order to achieve his short-
and medium-term career objectives he seeks to: a) develop advanced methodologic and analytic skills in
molecular epidemiology, phylogenetic analysis and bioinformatics; b) expand laboratory expertise in real-time
high-throughput next generation sequencing and accurate and reliable quantification of proviral reservoirs for
advancing HIV cure studies, and c) strengthen leadership abilities particularly in managing large scientific
projects, population-level surveys, and diverse research teams with expertise in different fields, organizational
leadership and student research supervision. Training activities will encompass formal training and
coursework, practical application through the proposed research project, and direct mentorship from my highly
experienced mentorship and advisory team. These activities will draw on the strengths of the mentorship team
and leading research institutions with strong collaborative ties and have a record of mentoring young
investigators to R01 and independence.
Research: The study aims to introduce an innovative approach to estimating HIV incidence, which is very
important for national HIV programs / public health, and also for HIV prevention research, but can be
expensive and challenging to do. The specific aims are: 1) To assess adjusted viral diversity as a potential
biomarker of HIV incidence. 2) To refine results of serological screening in subsets of true- and false-recent
cases, and patients with established infection (ART-naïve and on ART), by adjusted viral diversity. We will test
whether viral diversity within the most informative regions across the HIV-1C genome adjusted for multiplicity
of transmission, recombination, and level of viral replication could be used to refine the results of serological
screening and improve specificity and sensitivity. We expect that the adjusted viral diversity within the most
informative regions will increase specificity and sensitivity in estimation of HIV incidence within the 4 subsets of
individuals targeted in this Aim to ≥95%. Establishing a cost-effective algorithm to estimate incidence is of
critical public health importance in low resource settings.
项目摘要
候选人:Sikhulile Moyo博士坚定不移地致力于一个全面的职业生涯,专注于促进
结束艾滋病毒流行和相关的公共卫生紧急情况。他致力于寻找
评估干预措施影响和艾滋病毒治疗研究的成本效益工具。他设想
他本人作为全球领导者,致力于跟踪和消除新的艾滋病毒感染的研究,
开发艾滋病毒治疗方法,与研究人员、项目实施者和政策制定者合作,
干预措施的成本效益评价。Moyo博士的5年职业发展计划侧重于三个关键方面,
领域:遗传学、流行病学和生物统计学;跨部门发病率和实施;以及艾滋病毒
早期创始者病毒的治愈和表征,以及SARS-COV-2基因组学。为了实现他的短暂-
和中期职业目标,他寻求:a)发展先进的方法和分析技能,
分子流行病学、系统发育分析和生物信息学; B)实时扩展实验室专业知识
高通量下一代测序以及前病毒库的准确可靠定量,
推进艾滋病毒治疗研究,以及c)加强领导能力,特别是在管理大型科学研究方面
项目,人口水平的调查,以及在不同领域,组织
领导和学生研究监督。培训活动将包括正式培训,
课程,通过拟议的研究项目的实际应用,并从我的高度直接指导
经验丰富的指导和咨询团队。这些活动将利用导师团队的优势
和领先的研究机构有着强大的合作关系,并有指导年轻人的记录。
R 01和独立性。
研究:该研究旨在引入一种创新的方法来估计艾滋病毒的发病率,
这对国家艾滋病规划/公共卫生以及艾滋病预防研究都很重要,但也可以
昂贵且具有挑战性的工作。具体目标是:1)评估调整后的病毒多样性作为一种潜在的
HIV发病率的生物标志物。2)完善真和假近期感染者子集的血清学筛查结果
病例和确诊感染的患者(ART初治和ART治疗),通过调整病毒多样性。我们将测试
HIV-1C基因组中信息量最大区域内的病毒多样性是否调整了多重性
传播、重组和病毒复制水平的变化可用于完善血清学检测结果。
筛选,提高特异性和灵敏度。我们预计,调整后的病毒多样性在最
信息区域将增加4个子集内估计HIV发病率的特异性和敏感性,
本目标中针对的个体达到≥ 95%。建立一个成本有效的算法来估计发病率是
在低资源环境中至关重要的公共卫生重要性。
