Michael Hagmann, MSc.

I am a graduate research assistant at the StatNLP group, supervised by Prof. Dr. Stefan Riezler. My current research focus are the application and adapation of empirical methods for machine learning. I am also interested in differentialy private machine learning techniques and their application to medical data.
