Interdisciplinary Research Methods Core

核心包括四个专业领域：定量方法和生物统计学;定性方法和人种学;运筹学和数学建模;生物测量和分析。核心主任Trace Kershaw博士是耶鲁大学公共卫生学院的行为科学家和副教授，在国内外开展艾滋病毒行为和干预研究方面拥有超过12年的经验。Kershaw博士在使用基于技术的评估（例如ACASI，基于网络的，手持设备，手机），复杂设计（例如纵向，集群，随机对照试验，混合方法）和高级分析技术（例如多层次建模，二元数据分析，结构方程建模，潜在增长曲线，潜在类别分析，递归分区）方面具有专业知识。Kershaw博士曾担任几项CIRA附属研究的首席方法学家，包括Ickovics博士在纽约社区诊所对孕妇进行艾滋病毒预防干预的实施研究。这种广泛的专业知识使Kershaw博士有资格领导核心对实施科学的不断扩大的关注。克肖博士将监督核心活动的各个方面，包括主持核心会议，与核心科学家密切协调，实施和监督核心政策和程序，以确保它们是适当和有效的。除克肖博士外，核心小组还将由两名共同主任领导，他们具有核心小组运作所必需的专门知识。Jean Schensul博士是社区研究所的创始人和高级科学家，也是一位国际知名的医学人类学家，在社区艾滋病毒干预方面拥有25年以上的经验。她在定性和混合方法研究方面拥有专业知识，是一个备受赞誉的民族志方法的七本书系列的作者，目前正在修订第二版。纽约大学内科副教授Scott Braithwaite博士是运筹学、决策科学、数学建模以及成本和质量效益分析方面的专家。他的HIV疾病进展数学模型被认为是探索HIV临床干预措施最全面和最复杂的模型之一。联合主任将帮助克肖博士规划核心方向和活动，领导培训活动的发展，并监督磋商。罗素·巴塞博士将担任副主任，负责核心的日常运作，组织核心活动，提供数据分析和咨询服务，并监督核心评估和监测。Barclay博士是一位受过生态学研究培训的统计学家，拥有多元和纵向统计学，空间统计学，神经网络和高级采样技术的专业知识。其他贡献的核心科学家（图BI）将参加核心活动，包括研讨会，咨询和会议。除了核心科学家的专业知识外，ESCore还与耶鲁中心保持着持续的关系。 分析科学（YCAS）YCAS生物统计学家拥有广泛的技能和专业知识，包括 掌握一系列统计程序（如SPSS、SAS、R、Stata、M-Plus、SUDAAN和WinBugs），以及 了解大量的分析技术，包括网络分析，评估研究，多层次 建模和生存分析。作为这项合作的一部分，YCAS的一名博士统计学家将直接提供 为核心提供服务，包括进行咨询、分析和研讨会。另外核心 领导层将与YCAS对接，并根据需要将其他YCAS成员整合到核心活动中。

The Core embodies four areas of expertise: Quantitative Methods and Biostatistics; Qualitative Methods and Ethnography; Operations Research and Mathematical Modeling; and Biological Measures and Analysis. Dr. Trace Kershaw, Core Director, is a behavioral scientist and Associate Professor at Yale School of Public Health with over 12 years of experience conducting HIV behavioral and intervention studies domestically and internationally. Dr. Kershaw has expertise in using technology-based assessments (e.g. ACASI, web-based, hand held devices, cell phones), complex designs (e.g. longitudinal, clustered, randomized controlled trials, mixed methods), and advanced analytic techniques (e.g. multilevel modeling, dyadic data analysis, structural equation modeling, latent growth curves, latent class analysis, recursive partitioning). Dr Kershaw has served as the lead methodologist on several CIRA-affiliated studies including Dr. Ickovics' implementation study of her HIV prevention intervention for pregnant women in community clinics in New York. This breadth of expertise makes Dr. Kershaw well qualified to lead the Core's expanding focus on implementation science. Dr Kershaw will oversee all aspects of the Core's activities including chairing Core meetings, working in close coordination with Core scientists, and implementing and overseeing Core policies and procedures to ensure they are appropriate and efficient. In addition to Dr. Kershaw, the Core will be led by two Co-Directors with expertise essential to the functioning of the Core. Dr. Jean Schensul is founder of and Senior Scientist at The Institute for Community Research and an internationally known medical anthropologist with over 25 years of experience in the conduct of community-based HIV interventions. She has expertise in qualitative and mixed methods research and is the author of an acclaimed seven book series on ethnographic methods that is currently being revised for a 2nd Edition. Dr. Scott Braithwaite, Associate Professor of Internal Medicine at New York University, is an expert in operations research, decision science, mathematical modeling, and cost and quality effectiveness analysis. His mathematical models of HIV disease progression are known to be among the most comprehensive and sophisticated available for exploring HIV clinical interventions. The Co- Directors will help Dr Kershaw plan the Core direction and activities, lead the development of training activities, and oversee consultations. Dr Russell Barbour will serve as the Associate Director and will be in charge of the day to day functioning of the Core, organize Core activities, provide data analysis and consultation services, and oversee Core evaluation and monitoring. Dr. Barbour is a statistician trained in ecological studies with expertise in multivariate and longitudinal statistics, spatial statistics, neural networks, and advanced sampling techniques. Other contributing Core scientists (Figure BI) will participate in Core activities including seminars, consultations, and meetings. In addition to the expertise of its Core Scientists, IRM Core has an ongoing relationship with The Yale Center for Analytical Sciences (YCAS). YCAS biostatisticians have a breadth of skills and expertise including knowledge of a range of statistical programs (e.g. SPSS, SAS, R, Stata, M-Plus, SUDAAN, and WinBugs), and knowledge of a large group of analytic techniques including network analysis, evaluation research, multilevel modeling, and survival analysis. As part of this collaboration, one PhD statistician for YCAS will provide direct services to the Core including conducting consultations, analyses, and seminars. In addition, the Core leadership will interface with YCAS and integrate other YCAS members in Core activities as needed.
