About Me


I am Oana, postdoctoral researcher at Max Planck Institute in the team of Gerhard Weikum.

I received my Ph.D. from Télécom ParisTech University and my advisor was Mauro Sozio.
My research interests lie in the area of data mining, with a focus on graph mining and computational social science.

Originally I am from Romania and more exactly Rucăr, a village in the Carpathian Mountains.

Teaching

I really enjoy teaching.
I supervised classes on the frameworks Apache Hadoop and Apache Spark. You can find here a short introduction to Apache Hadoop.

Miscellaneous

In my free time I enjoy reading, cycling and learning to play the guitar.
My sister writes very nice stories and travel impressions (in Romanian).
