PROJECT SUMMARY/ABSTRACT Since becoming an Associate Professor two and a half years ago, I think back to my years as an Assistant Professor and realize that my greatest moments of joy came from my mentee’s successes. Moments where they were awarded their first grant, obtained their first faculty position and a high-impact first authored paper was accepted all shine brightly in my memories. Equally important were the moments where a trainee came to see me because they were feeling unsuccessful or unmotivated, and they felt they were not going to succeed in academics, and through our conversation they arose, reassured about their good ideas, skill set and ability to move forward in a positive and productive way. Looking forward, I worry about the amount of time committed to administrative and clinical efforts and believe that obtaining protected time via this K24 will directly lead to development and enrichment in three areas: 1. Mentoring, 2. Conducting cutting-edge novel research, and 3. Learning new patient oriented research skills. I truly believe that expanding my time dedicated to mentorship will have the greatest impact out of the three, because enhancing and supporting the training of passionate, clever, dedicated trainees will lead to broader effects across medicine and academics relative to my research alone. In terms of research, e-cigarettes are drug delivery (vaping) devices that entered the country in 2007 and have exploded in terms of use, especially in adolescents and young adults whom have never smoked. We have no longitudinal data on the health effects of vaping, particularly on lung and systemic inflammation. By leveraging our existing cohort of young e-cigarette vapers at UCSD, the research proposed here can obtain longitudinal data by having these subjects return at 1 and 2 years, thus giving 3 timepoints across which changes in airway inflammation, microbiome and reactivity, and systemic inflammation can be defined. These data will help us understand which chronic diseases will arise from chronic e-cigarette use. Asthmatics are using e-cigarettes at a high rate, most likely because of the successful advertising campaigns tobacco companies have run, convincing many of the lack of adverse effects of these devices. But patients with asthma have airways and systemic inflammation, thus they are likely to be more susceptible to the pro-inflammatory and immunomodulatory effects of vaping. By again leveraging the ongoing patient-oriented research conducted by our team, I propose here to recruit vaping and non-vaping subjects with TH2-high allergic asthma to assess the effects of e-cigarette aerosol inhalation on their underlying disease state. Finally, I propose to dive deeper into clinical research design and analysis, to improve my ability to conduct high level patient oriented research and thus yield the highest quality, relevant data possible. With the support of my own mentors (Drs. Atul Malhotra and Victor Nizet), the support of UCSD, my existing fantastic research team and the mentees to come, I believe the support of this K24 will make it possible to thrive as a mentor, researcher and life-long learner.

项目总结/摘要 自从两年半前成为副教授以来，我回想起我作为助理的岁月 教授，并意识到我最大的快乐来自于我的学员的成功。在那些时刻 获得了他们的第一笔赠款，获得了他们的第一个教师职位，并发表了一篇具有高影响力的第一篇论文。 接受一切在我的记忆中闪耀。同样重要的是，当一个受训者看到 我，因为他们感到不成功或没有动力，他们觉得他们不会成功， 通过我们的谈话，他们站了起来，对他们的好主意，技能和能力感到放心， 以积极和富有成效的方式前进。展望未来，我担心投入的时间 行政和临床努力，并认为通过此K24获得受保护的时间将直接导致 在三个方面发展和丰富：1.指导，2.进行前沿的小说研究，3。 学习新的以病人为导向的研究技能。我真的相信，扩大我的时间致力于指导将 在这三者中影响最大，因为加强和支持热情，聪明， 与我的研究相比，敬业的学员将在医学和学术领域产生更广泛的影响。在 就研究而言，电子烟是2007年进入该国的药物输送（vaping）设备， 在使用方面，特别是在从未吸烟的青少年和年轻人中，使用量激增。我们没有 电子烟对健康影响的纵向数据，特别是对肺部和全身炎症的影响。通过利用 我们现有的UCSD年轻电子烟vapers队列，这里提出的研究可以获得纵向 这些受试者在1年和2年时返回，因此提供了3个时间点， 可以定义炎症、微生物组和反应性以及全身性炎症。这些数据将帮助我们 了解哪些慢性疾病会因长期使用电子烟而引起。哮喘患者正在使用电子烟， 高比率，很可能是因为烟草公司成功的广告宣传， 令人信服的缺乏这些设备的许多不利影响。但是哮喘患者有呼吸道， 全身性炎症，因此他们可能更容易受到促炎和 vaping的免疫调节作用。通过再次利用正在进行的以患者为导向的研究， 我们的团队，我建议在这里招募患有TH 2高过敏性哮喘的vaping和非vaping受试者，以评估 电子烟雾化吸入对其基础疾病状态的影响。最后，我建议更深入地研究 临床研究设计和分析，以提高我进行高水平患者导向研究的能力， 从而产生尽可能高质量的相关数据。在我自己的导师的支持下（阿图尔·马尔霍特拉博士 和维克托尼泽特），加州大学圣地亚哥分校的支持，我现有的出色的研究团队和学员来，我相信， 这个K24的支持将使其能够茁壮成长为导师，研究人员和终身学习者。
