Michaela Götz

I am a fifth year PhD student working with Johannes Gehrke in the database group at Cornell University.

Prior to this, I spent a semester at Carnegie Mellon University working with Christos Faloutsos on modeling blog dynamics. I obtained a B.S. in Computer Science at Saarland University in Saarbrücken, Germany.

I am interested in data management. Currently I work on data privacy, data cleaning and workload-aware indexing techniques for social networks.
