I joined a new collaboration which was doing a large radio survey of superluminous supernova (SLSN) remanants. I wrote a comparison between my method and their method of determining pulsar parameters from optical light curves, and altered my code to generate radio light curves in a consistent way. We published the survey results and pulsar constraints, and found that the model, with the assumptions we are currently using, is inconsistent with several supernovae.I continued working on code for determining optical spectra, but decided to collaborate with a group that has already developed similar code. We are modeling these spectra now.I wrote my PhD thesis and graduated.

我加入了一个新的合作，这是做一个大型的无线电调查超亮超新星（SLSN）残留物。 我写了一个比较我的方法和他们的方法确定脉冲星参数的光学光变曲线，并修改了我的代码，以产生一个一致的方式无线电光变曲线。 我们公布了调查结果和脉冲星的约束条件，发现我们目前使用的假设模型与几颗超新星不一致。我继续编写确定光谱的代码，但决定与一个已经开发出类似代码的小组合作。 我们现在正在模拟这些光谱。我写了我的博士论文并毕业了。
