DESCRIPTION (provided by applicant): Dr. Dongju Seo is an associate research scientist in the Department of Psychiatry at Yale University specializing in functional magnetic resonance imaging (fMRI). Dr. Seo received a Ph.D. in Clinical Psychology from the University of Minnesota, Twin Cities in 2008 and subsequently completed postdoctoral training at Yale University with a focus on stress and addiction. The long-term goal of the candidate is to develop an interdisciplinary program of research to competitively conduct and interpret translational neuroscience research on alcoholism using multimodal neuroimaging and connectivity mapping. Specifically, her research focuses on stress- and autonomic nervous system (ANS)- related neural dysregulation associated with heavy alcohol use, discovering vulnerability markers for alcoholism risk, and developing effective prevention and treatment strategies. Her short-term goal is to obtain the skills and resources required to achieve her long-term goals and to become an independent researcher through the training and support provided by this K08 Award. Her preliminary findings indicate that binge and heavy alcohol use is influenced by a functional disconnectivity between the VmPFC regulatory system and the ANS arousal regions, brain areas involved in the modulation of emotions and rewarding states. Based on this result, it is hypothesized that decreased functional connectivity in the VmPFC-ANS circuit contributes to emotional and ANS disruption and alcohol intake in heavy social drinkers. The candidate aims to test this hypothesis in a larger sample and seeks support to learn new skills for this study. Her research strategy will be to examine brain and ANS response in heavy and light social drinkers using simultaneous fMRI and ANS recording, functional connectivity mapping, and combined clinical design to identify neural measures associated with risk for alcohol abuse. Her training program will cover the following topics relating to the interdisciplinary neuroscience of alcoholism: 1) learning fMRI connectivity mapping and translational neuroscience of alcoholism 2) combining fMRI and ANS techniques and analysis, and 3) developing expertise in longitudinal study design and analysis for alcohol research. Her mentors include internationally prominent experts in translational research on alcoholism (Rajita Sinha, Ph.D.; John H. Krystal, M.D.), multimodal neuroimaging and connectivity mapping (Todd Constable, Ph.D.) and longitudinal research on alcoholism (Howard Tennen, Ph.D.; Ralitza Gueorguieva, Ph.D.). The K08 Award will allow the candidate to acquire new skills and resources to test the hypothesis and provide Dr. Seo with a valuable opportunity to grow into an independent clinical investigator, with expertise in the application of state-of-the art, multimoda neuroimaging techniques to conduct translational neuroscience research on alcoholism.

描述（由申请人提供）：Dongju Seo 博士是耶鲁大学精神病学系的副研究科学家，专门研究功能磁共振成像 (fMRI)。 Seo 博士获得博士学位。 2008 年在明尼苏达大学双城分校获得临床心理学博士学位，随后在耶鲁大学完成了博士后培训，重点研究压力和成瘾问题。候选人的长期目标是开发一个跨学科的研究计划，利用多模态神经影像和连接映射，有竞争力地进行和解释酗酒的转化神经科学研究。具体来说，她的研究重点是与大量饮酒相关的压力和自主神经系统（ANS）相关的神经失调，发现酗酒风险的脆弱性标记，并制定有效的预防和治疗策略。她的短期目标是通过本次 K08 奖提供的培训和支持，获得实现长期目标所需的技能和资源，并成为一名独立研究员。她的初步研究结果表明，暴饮暴食和大量饮酒受到 VmPFC 调节系统和 ANS 唤醒区域（涉及情绪调节和奖励状态的大脑区域）之间功能性脱节的影响。基于这一结果，我们假设 VmPFC-ANS 回路中功能连接的减少会导致社交饮酒者的情绪和 ANS 破坏以及酒精摄入。候选人的目标是在更大的样本中检验这一假设，并寻求支持以学习本研究的新技能。她的研究策略是使用同步功能磁共振成像和 ANS 记录、功能连接映射和组合临床设计来检查重度和轻度社交饮酒者的大脑和 ANS 反应，以确定与酒精滥用风险相关的神经测量。她的培训计划将涵盖以下与酒精中毒跨学科神经科学相关的主题：1）学习酒精中毒的功能磁共振成像连接图和转化神经科学2）结合功能磁共振成像和ANS技术与分析，3）发展酒精研究纵向研究设计和分析的专业知识。她的导师包括酗酒转化研究（Rajita Sinha，博士；John H. Krystal，医学博士）、多模式神经影像和连接图谱（Todd Constable，博士）和酗酒纵向研究（Howard Tennen，博士；Ralitza Gueorguieva，博士）方面的国际知名专家。 K08 奖将使候选人获得新的技能和资源来检验假设，并为 Seo 博士提供宝贵的机会，成长为一名独立的临床研究者，拥有应用最先进的多模式神经影像技术进行酒精中毒转化神经科学研究的专业知识。
