About Me

Hello! I am Oana, currently a postdoctoral researcher at Telecom ParisTech. I received my Ph.D. on the 17th of May, 2017 and my advisor was Mauro Sozio. You can find here the slides of my defense. My research interests lie in the area of data mining, with a focus on graph mining and computational social science.

Previously I attended the Parisian Master of Research in Computer Science (MPRI), while being in the Paris Graduate School of Mathematics program (PGSM). I completed my bachelor in Computer Science, at the University of Bucharest. I was a software engineer at Bitdefender, a security software company.

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

Research

My Ph.D. work was focused on graph mining and scalable algorithms, with the final goal of improving state-of-the-art on event detection in social media.

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).
