The PhD thesis programme will constist in using current and future imaging and spectroscopic surveys to measure physical properties (e.g. stellar mass, sfr, metallicities, star-formation timescales/stochasticity, star-formation histories) of main-sequence galaxies spanning cosmic time using BEAGLE, a bayesian spectral and SED-fitting code. Analysis of individual objects will be self-consistently propagated to population-wide measurements using Bayesian methods. The project will most likely also involve participating in the guaranteed time observing programme of the James Webb Space Telescope. The results of this research program will provide new important insights on the mechanisms and physical processes responsible for the early formation of galaxies and their subsequent evolution across the cosmic epochs.

博士论文计划将constist在使用当前和未来的成像和光谱调查测量物理特性（例如恒星质量，sfr，金属丰度，恒星形成时间尺度/随机性，恒星形成历史）的主序星星系跨越宇宙时间使用BEAGLE，一个bastolic光谱和SED拟合代码。对单个物体的分析将使用贝叶斯方法自洽地传播到整个群体的测量。该项目很可能还涉及参与詹姆斯·韦伯空间望远镜的保证时间观测方案。这项研究计划的结果将为负责星系早期形成及其随后在宇宙时代的演变的机制和物理过程提供新的重要见解。
