I graduated from Warwick University in Maths and Physics in 2021, where I acquired an interest in fluid dynamics and, subsequently, plasma physics. I am particularly interested in turbulence and the difficulties associated with its precise definition and modelling. My undergraduate project involved investigating transitions from turbulent to laminar states in the plasma interchange model. My interest in plasma physics led me to study Fusion Energy for my MSc at University of York in 2022-23 and my final project there involved applying uncertainty quantification to the parameter space of a plasma filament model to investigate particle transport through tokamak scrape-off layers. Fusion represents an opportunity to simultaneously engage in my areas of academic interest and contribute to the development of a technology with the potential to actively benefit our society.My research will be based at CCFE, supervised by David Dickinson from University of York and Ben Chapman-Oplopoiou from UKAEA. The aim of the project is to understand the turbulent transport of heat and particles through the pedestal region of spherical tokamaks by using the GENE gyrokinetic code. Data from MAST and MAST-U indicates that turbulence in the pedestal region is primarily driven by certain electromagnetic microinstabilities which we hope to compare using GENE and thereby characterise the dominant transport mechanisms. Once we have an understanding of how different instabilities affect pedestal transport, we aim to apply these findings to make transport predictions for future STEP pedestals.

我于2021年毕业于沃里克大学数学与物理专业，在那里我对流体动力学产生了兴趣，随后又对等离子体物理产生了兴趣。我对湍流及其精确定义和建模的困难特别感兴趣。我的本科项目涉及研究等离子体交换模型中从湍流到层流状态的转变。我对等离子体物理的兴趣使我在2022-23年在约克大学攻读硕士学位，我的最后一个项目涉及将不确定性量化应用于等离子体灯丝模型的参数空间，以研究通过托卡马克刮除层的粒子传输。融合代表了一个机会，同时从事我的学术兴趣领域，并有助于发展一种技术，有可能积极造福我们的社会。我的研究将在CCFE，由约克大学的大卫迪金森和UKAEA的本查普曼-Oplopoiou监督。该项目的目的是通过使用GENE回旋动力学代码来理解热量和粒子通过球形托卡马克基座区域的湍流输运。来自MAST和MAST-U的数据表明，基座区域的湍流主要是由某些电磁微不稳定性驱动的，我们希望使用GENE进行比较，从而确定占主导地位的传输机制。一旦我们有一个不同的不稳定性如何影响基座运输的理解，我们的目标是应用这些研究结果，使未来的STEP的轨道交通预测。
