Stefan Siegert

I'm an Associate Professor in Data Science at the University of Exeter. I have a PhD in Physics from TU Dresden, followed by two post-docs and a lectureship in Statistics at Exeter.

I try to be good at being a husband, father, scholar, athlete, artist — to varying degrees of success. See my now page for what I'm up to at the moment.

I was born in Germany in 1984. I now live in Exeter/Devon (UK) with my wife and three kids.

University

My students and I work on theory and application of statistical modelling and machine learning. We develop mathematical methods that help us use observation data and computer simulations to understand the past and predict the future.

I have taught undergraduate and graduate mathematics courses at University of Exeter:

• Foundations (MTH1000)
• Probability, Statistics, Data (MTH1004)
• Statistical Inference (MTH3028)
• Advanced Statistical Modelling (ECM3904)
• Applications of Machine Learning and Statistics (MTHM503)
• Uncertainty Quantification (MTHM063)

• Advanced Statistics Training for PhD students
• Statistics and Machine Learning Training for Meteorologists
• Introduction to Machine Learning and Neural Networks

Notes

• Quick Bayesian updating via the "skeptic's conversion number"
• Simulating wifi coverage ("Helmhurts" in R)
• Simulating alcohol intoxication with a pharmacokinetic model
• A simple agent-based model of infectious disease spread implemented in base R
• Training a physics-informed neural network (PINN) on the 1-d advection equation
• Quick and dirty error bars for histogram counts
• Important concepts in formal logic
• Sampling a 2d Gaussian process
• Smoke (random art)
• Circular noise (random art)
• Schotter (random art) in ggplot
• Ggplot calligraphy
• My footbag/juggling videos
• Animated 2D generative art in R
• A useful proof concerning the CRPS
• Writing (Notes and links)
