Hannah Blocher

I started as a PhD student at the Institute of Statistics in February 2021. I obtained a Bachelor's Degree (B.A.) in Mathematics form the LMU Munich and a Master's Degree (M.Sc) ins Statistics form the LMU Munich

My current research focus is on embedding data depth functions into the theory of formal concept analysis. With this we define statistical models and tests.

Research Interests:

• Data Depth Functions
• Formal Concept Analysis
• Partial Orders
• (Spatial Statistics, Decision Theory)
