Quantitative risk management is a central topic in the fields of insurance and finance, where researchers and practitioners seek the advanced analytic tools and computational methods for better identification, characterization, assessment, management and mitigation of the emerging risks. In the insurance industry, it is of utmost importance to develop such quantitative risk management systems for the solvency risk pertaining to the insurer's ability to meet its future financial obligations. My proposed research program is expected to make significant contributions in this research field through the development and application of analytical approaches and computational methodologies in the study of surplus processes with perturbations in its trajectory. More specifically, my research team and I will concentrate on the following three themes: (1) Stochastic modeling and optimal design with surplus-dependent features; (2) Develop and analyze (surplus-dependent) risk measures for insurance risk processes; (3) Discover potential applications in variable annuities. In Theme (1), following the recent trend in the analysis of an insurer's dynamic cash flows, risk models with surplus-dependent features will be designed and examined to meet the various needs of different parties in insurance practice. Theme (2) studies the surplus-dependent risk measures with a special focus on the drawdown related measures, in order to help provide deeper insight into the characteristics of potential hazards and assist in the early detection of extreme risks. We will also build the connections between ruin theory and risk measures via probabilistic analysis. The integrated outcomes from Themes (1) and (2) will improve the quantitative risk management of solvency risk through the innovative design of dynamic strategies and measurement of the exposures over time. Another contribution of my proposed research program is to expand on the application of exotic risk theory and surplus-dependent risk measures to the pricing and risk management of variable annuity, which is the focus of Theme (3). This research will provide innovative insights for researchers and practitioners in the insurance and finance industries, and train HQP who will be prepared to lead in the related research areas.**

定量风险管理是保险和金融领域的核心话题，研究人员和从业人员在这里寻求先进的分析工具和计算方法，以更好地识别，表征，评估，管理和缓解新兴风险。在保险行业中，开发这种定量风险管理系统至关重要，以实现与保险公司履行其未来财务义务的能力有关的偿付能力风险。我提出的研究计划有望通过开发和应用分析方法和计算方法论在其轨迹中扰动的盈余过程中的开发和应用来做出重大贡献。更具体地说，我和我的研究团队将专注于以下三个主题：（1）随机建模和最佳设计，具有多余的功能； （2）开发和分析保险风险过程的风险措施（剩余）； （3）在可变年金中发现潜在的应用。在主题（1）中，按照对保险公司动态现金流的分析的最新趋势，将设计和检查具有剩余功能的风险模型，以满足保险实践中不同当事方的各种需求。主题（2）研究了剩余的风险措施，特别关注与缩减相关的措施，以帮助您深入了解潜在危害的特征并帮助早期发现极端风险。我们还将通过概率分析建立废墟理论与风险措施之间的联系。主题（1）和（2）的综合结果将通过动态策略的创新设计和随着时间的推移的暴露量来改善偿付能力风险的定量风险管理。我拟议的研究计划的另一个贡献是扩展异国风险理论和剩余风险措施的应用对可变年金的定价和风险管理，这是主题的重点（3）。这项研究将为保险和金融行业的研究人员和从业人员提供创新的见解，并培训HQP，他们将准备领导相关研究领域。**
