Trosolwyg
I am a final year PhD student in the School of Mathematics. My research spans several disciplines, but is largely focused in the cross-section between statistics and data science. I use methods from linear algebra and optimization to explore data analysis methods, particularly when applied to high-dimensional datasets.
My PhD has focused on the use of distance measures in high-dimensional spaces, and the development of new distance measures to counteract the so-called curse of dimensionality. The application of such research is broad, as distance measures are heavily relied upon in statistical, data science and machine learning methods.
