Stefan Stein

I am a second year PhD student in the Department of Statistics at the University of Warwick and work under the supervision of Prof. Chenlei Leng. I received my bachelor's and master's degree in mathematics from the University of Heidelberg, Germany.

I am on an Industrial Cooperative Awards in Science & Technology (ICASE) studentship and my funding is partially provided by Tata Steel.

Aside from statistics and mathematics, I am interested in cyber security, machine learning and distributed ledger technology. If you would like to have a chat about these things, feel free to get in touch.

Research Interests

Together with Tata Steel I am working on process optimisation and machine learning topics for steel manufacturing. We developed a guided analytics framework that allows the statistically untrained users to use state of the art statistical methods to extract optimal configurations for manufacturing parameters.

I am also interested in devising new methods for analysing large complex data sets that are high-dimensional or networked in nature. Currently I am researching a novel model for sparse networks that combines methods from stochastic network theory with those of high-dimensional data analysis.
