Prof. Dr. Doerfel holds a professorship in data science. At the Institute for Data Science (IfDS) at the Faculty of Media, he is responsible for the English-language modules "Mathematics and Multivariate Statistics," "Machine Learning," "Deep Learning," and "Advanced Topics in Data Mining." He is also one of the organizers of the "Application Project" module.

Information on the individual courses is available in the module database.

Stephan Doerfel studied mathematics (Diplom degree) with a minor in economics at the Technical University of Dresden and at Lund University (Sweden). He earned his Ph.D. from the University of Kassel in the field of knowledge discovery, where, as a research assistant, he focused on topics including the application of machine learning to metadata from scientific literature, recommender systems, scientometrics, and network analysis. 
From 2016 to 2022, Stephan Doerfel worked for Micromata GmbH, where he served as a software engineer and data scientist on various projects. He also coordinated the company’s Tech Guild, promoting technical exchange and innovation.
Since 2021, he has been a professor of data science at Kiel University of Applied Sciences (HAW Kiel).

Stephan Doerfel is originally from Cottbus, where he attended the Max-Steenbeck-Gymnasium (graduated in 2002). Come rain or shine, he occasionally heads out into nature to go geocaching.

Stephan Doerfel’s research contributes to the field of applied data science. He focuses on applying machine learning and data analysis methods to address complex problems across a wide range of disciplines.

He also regularly serves as a member of program committees for international conferences (including ECML/PKDD and WebSci) and as a reviewer for academic journals (including Knowledge-Based Systems).
