Ioana-Oriana Bercea

I am a (tenure-track) Assistant Professor. I am interested in the broad area of Theoretical Computer Science and specifically in

• Data Structures (e.g. dictionaries and Bloom filters)
• Randomized and Approximation Algorithms (e.g. hashing, clustering)
• Computational Geometry (e.g. Traveling Salesman Problem)

Previously, I was a Postdoc in the  Basic Algorithms Research Copenhagen (BARC) group  at the IT University of Copenhagen, hosted by Prof. Thore Husfeldt. Before joining BARC, I was a Postdoc at Tel Aviv University, hosted by Prof. Guy Even.

I obtained my PhD in Computer Science from the University of Maryland, where I had the privilege of being advised by Prof. Samir Khuller. I obtained my Master's degree from UMD under the supervision of Prof. Aravind Srinivasan. I graduated from the University of Chicago, with a Bachelor of Science in Mathematics (Honors) and Computer Science.

My CV can be found here and a list of my publications can be found on dblp. I also maintain a webpage here which includes a more comprehensive list of publications.

P.S. I usually go by Ioana, rather than Ioana-Oriana.
