Dr. Theresa Ullmann and Julian Lange receive prizes from the German Association for Medical Informatics, Biometry and Epidemiology (GMDS)

Dr. Theresa Ullmann and Julian Lange have received prizes from the German Association for Medical Informatics, Biometry and Epidemiology (GMDS) for their theses supervised by Prof. Dr. Anne-Laure Boulesteix. Congratulations!

Dr. Theresa Ullmann was awarded the prize for the best dissertation in the field of Medical Biometry for her PhD dissertation entitled "Evaluation of clustering results and novel cluster algorithms: A metascientific perspective", on which she worked as part of the Munich Center for Machine Learning (MCML). From 2019 to 2022, Dr. Ullmann was a PhD student in the working group of Prof. Boulesteix. In 2023, she moved to the Medical University of Vienna as a postdoctoral researcher. Dr. Ullmann's dissertation deals with validation, replicability and overoptimism in the context of cluster analysis. The cumulative dissertation first examined how clustering results can be verified using validation data in order to assess their reliability and generalizability. Dr. Ullmann also analyzed to which extent clustering results in applied research are affected by overoptimism. However, overoptimism is not only a potentially relevant problem in applied research but also in methodological research. The PhD thesis thus also investigated which mechanisms lead to an overoptimistic presentation of new clustering algorithms.

Julian Lange was awarded the prize for the best master’s thesis in the field of Medical Biometry for his work entitled "Confirmatory studies in methodological statistical research: concept and illustration". Julian Lange is a PhD student in the working group of Prof. Boulesteix as part of the MCML.
