As an undergraduate, I did a BSc in physics at the Universidad Autónoma Metropolitana in Mexico City, specializing in plasma physics. I then did a year in Paris studying a master's in physics focused on simulating magnetically confined plasmas. Through my early years, I became fascinated with the idea of fusion energy. Now, I am proudly starting a PhD, researching "Flexible Grids For Complex Tokamak Topologies" with Dr. Peter Hill.Magnetically confined fusion devices called tokamaks are one of the most promising devices to achieve commercial fusion. Their exhaust systems, called divertors, are of particular importance as the complex physics in that region sets the boundary conditions "upstream" for the fusion-producing core, and so ultimately the power production. Advanced divertor designs, such as the "super-X" and "snowflake" divertors can have complex magnetic geometries and topologies which can make simulating them a challenging task.The project's objective is to adapt and extend the world-leading open-source BOUT++ framework to better handle advanced divertor designs by developing and testing a new mesh implementation in C++. The new mesh will then be used to study the effect of the shape of these advanced designs on the upstream conditions and compare simulations to experimental results from the UK's MAST-U tokamak.

作为一名本科生，我在墨西哥城的自治大学获得了物理学学士学位，专攻物理学，然后在巴黎攻读了一年的物理学硕士学位，专注于模拟磁约束等离子体。现在，我正在自豪地开始攻读博士学位，与 Peter Hill 博士一起研究“复杂托卡马克拓扑的灵活网格”。磁约束聚变装置托卡马克是最有希望实现商业聚变的装置之一，它们的排气系统（称为偏滤器）特别重要，因为该区域的复杂物理现象为聚变核心设定了“上游”边界条件，最终决定了功率。先进的偏滤器设计，例如“super-X”和“雪花”偏滤器可以具有复杂的磁性几何形状和拓扑，这使得对其进行模拟成为一项具有挑战性的任务。该项目的目标是适应和扩展世界领先的技术。开源 BOUT++ 框架通过在 C++ 中开发和测试新的网格实现来更好地处理先进的偏滤器设计。然后，新的网格将用于研究这些先进设计的形状对上游条件的影响，并将模拟与实验结果进行比较。来自英国的 MAST-U 托卡马克。
