Project Summary The purpose of the present K02 Independent Scientist Award is threefold: first, to provide structured career development activities in psychiatric, statistical, and molecular genetics, second, to deepen my knowledge of alcohol-related phenotypes, and third, to apply these skills to the analysis of the rich genomic data yielded from my current R01, my other funded projects, as well as other data available at my institute. These goals stem directly from my funded projects and represent expansions in my current areas of expertise. Specifically, although I have the skill set needed to meet the genetic Aim of my current NIAAA R01 (AA020179 "Stress- induced Drinking in OEF/OIF Veterans: the Role of Combat History and PTSD" which is ongoing) I need increased training to fully utilize the data to ask new and deeper questions that are on the cutting edge of alcohol genetics research. Since my original training (in candidate gene designs) the field of genetics has changed significantly and increased in sophistication (e.g., genome wide association [GWAS] platforms, exom arrays, methylation arrays). These new platforms have introduced a number of analytic complexities, with multiple decision points in every stage of the process, from data cleaning to analysis to the interpretation of results. Thus, this K02 will give me the skills in the integration and harmonization of genomic data on multiple platforms (e.g., sequence, methylation, expression) to better utilize (beyond the original, now outdated aim) my NIAAA R01 data on the genomic influences on stress reactivity and subsequent alcohol use in soldiers. This aim will be achieved by hands-on training in molecular and epigenetics (including wetlab immersions), supervised statistical genetic analyses done in collaboration with leaders in the field, formal coursework and workshops, and individual tutoring by K02 consultants. Additionally, the K02 will deepen my expertise in the area of alcohol-related phenotypes, beyond stress-induced drinking, which has been the focus of my work to date. This aim will be achieved through directed readings, formal coursework, practical experience analyzing relevant datasets (e.g., NIAAA R37011408 "A Longitudinal Study of Genes, Environment and Alcohol Misuse in College Students"), and mentorship from leaders in the field (Dr. Kenneth Kendler). In summary, the overarching goal of the proposed K02 is to further my multidisciplinary independent program of research which aimed at the identification of risk and resilience factors, both biologic and psychosocial in nature, for traumatic stress related conditions (alcohol use disorders [AUDs], posttraumatic stress disorder [PTSD]) and translation of these findings into prevention and intervention programming. The K02 will provide me with protected time to fully engage in the training activities I have outlined, enabling me to coalesce my diverse training background and move my research program forward in ways not previously possible.

项目摘要 K 02独立科学家奖的目的有三个：第一，提供结构化的职业生涯 在精神病学，统计学和分子遗传学方面的发展活动，第二，加深我对 酒精相关的表型，第三，应用这些技能来分析丰富的基因组数据， 我目前的R 01，我的其他资助项目，以及我的研究所提供的其他数据。这些目标源于 直接来自我资助的项目，并代表我目前专业领域的扩展。具体地说， 虽然我有满足我目前的NIAAA R 01（AA 020179“压力- OEF/OIF退伍军人中的诱导饮酒：战斗历史和创伤后应激障碍的作用“，正在进行中） 增加培训，充分利用数据提出新的和更深入的问题，这些问题是最前沿的 酒精遗传学研究自从我最初的训练（在候选基因设计），遗传学领域已经 显著地改变并增加了复杂性（例如，全基因组关联平台，外显子 阵列、甲基化阵列）。这些新平台引入了许多分析复杂性， 从数据清理到分析，再到解释， 结果因此，这K 02将给我的技能，在整合和协调基因组数据的多个 平台（例如，序列，甲基化，表达），以更好地利用（超越原来的，现在已经过时的目标）我的 NIAAA R 01关于基因组对士兵应激反应和随后饮酒影响的数据。这 目标将通过分子和表观遗传学方面的实践培训（包括湿实验室浸入）实现， 与该领域的领导者合作进行的监督统计遗传分析，正式的课程， 研讨会和K 02顾问的个人辅导。此外，K 02还将加深我在 酒精相关的表型领域，除了压力诱导的饮酒，这一直是我工作的重点， 约会这一目标将通过指导性阅读、正式课程、实践经验分析来实现 相关数据集（例如，NIAAA R37011408《基因、环境和酒精滥用的纵向研究》 在大学生”），并指导领导人在该领域（肯尼思肯德勒博士）。总而言之， 拟议的K 02的总体目标是进一步我的多学科独立研究计划， 旨在确定创伤性疾病的风险和复原力因素，包括生物和心理社会因素， 应激相关疾病（酒精使用障碍[AUD]，创伤后应激障碍[PTSD]）和翻译 将这些发现纳入预防和干预方案。K 02将为我提供受保护的时间 我充分参与我所概述的培训活动，使我能够结合我的各种培训背景 以前所未有的方式推进我的研究计划
