Stefanie Peschel

PhD candidate in Biostatistics

Hey, my name is Stefanie. I am a doctoral candidate in Biostatistics at the LMU Munich, supervised by Professor Anne-Laure Boulesteix. I am also affiliated with the MCML (Munich Center for Machine Learning).

I started my PhD at the Institute of Asthma and Allergy Prevention at the Helmholtz Zentrum München and now continue my work in the Biomedical Statistics and Data Science group of Professor Christian L. Müller.

I studied Statistics with an Economic and Social Science Background at the LMU. My master’s thesis was my first foray into the world of microbial network analysis, which formed the basis of my doctoral studies. My research topics include analyzing microbial compositional data, network analysis and comparison, differential association testing, and permutation p-value approximation.

Besides my scientific activities, I also lead the Early Career Working Group (AG Nachwuchs) of the IBS-DR.
