Bridging AI research and enterprise impact.

Business Data Science & Applied AI Former Technical Lead Analytics & AI

Peer-reviewed research, production-grade AI, and a network of specialists helping a select group of organisations turn artificial intelligence into commercial results.

Advisory & Consulting

We take on a small number of engagements at a time and work them end-to-end, backed by a network of data scientists and software engineers.

Academy

We provide a broad range of training programmes designed around your organisation’s specific needs, data, tools, and business challenges. Drawing on a trusted network of highly qualified scientists and subject-matter experts, we combine academic depth with practical relevance.

Python & Automation

From your first script to a working automation: Python foundations, data handling, APIs.

Business Data Science

Predictive modelling on the tabular and time-series data you already hold — features, validation, and deployment.

Generative AI & LLMs in Practice

Prompting, retrieval-augmented generation, agents, and evaluation — systems that outlast the demo.

AI for Decision-Makers

Non-technical, for executives and managers: what is possible, where value sits, how to govern it.

About

I am Professor of Mathematics, in particular Business Data Science, at Hochschule Bielefeld (HSBI), and former Technical Lead Analytics & Artificial Intelligence at BASF. I started out in investment banking and quantitative finance; a doctorate in applied statistics on natural language processing and machine learning moved me into AI.

At BASF I led international AI initiatives from strategy through production deployment, and received the company’s highest performance rating in two consecutive years. Today I combine research, teaching, open-source development and selected industry collaborations to advance the practical application of AI.

My work on statistics, NLP, tabular deep learning, and the optimisation of AI systems is regularly published in leading journals and at major AI and data science conferences.

I hold Master’s degrees from Oxford and St Andrews and completed my doctorate summa cum laude in Göttingen, supported by a scholarship from the Studienstiftung des deutschen Volkes.

Summer Schools

With Dr. Knut Zoch, Research Fellow at CERN, formerly at Harvard University, I co-founded and lead Bridging AI & Society, an interdisciplinary summer school pairing the technical foundations of machine learning with the ethical, legal, and societal dimensions of AI. It has run as part of the summer academies of the Studienstiftung des deutschen Volkes since 2019.

Themes

Core ML concepts and methods, hands-on data work in Python, and AI’s societal impact.

Editions

Obertauern 2026 · Banz Abbey 2025 · Ljubljana 2024 · Koppelsberg 2021 · Cambridge (St John’s College) 2019.

Research

I turn frontier machine learning into methods that work in production: deep learning for structured data, language, and decisions under uncertainty.

Tabular Deep Learning

Most business data is tabular. I research how deep learning applies to it.

Natural Language Processing

LLM-based classification, information extraction, and ensembles for text.

Agentic AI Systems

LLM agents that plan, use tools, and act — made reliable in production.

Explainable & Trustworthy AI

Interpretable model behaviour, so AI can be trusted in high-stakes decisions.

Predictive Analytics

Time-series models that turn historical data into forward-looking decisions.

Statistics

Distributional regression and empirical methods that quantify uncertainty.
