Graduate Students

Dora Erdos

In 2008 I received my diploma (Msc + Bsc) in mathematics from Eotvos Lorand University in Budapest where I was fortunate to have Andras Frank as my advisor.
My research focuses on data mining, in special combinatorial optimization, algorithmic data analysis, with emphasize on social network analysis. Identification of important nodes in networks, graph reconstruction.

Behzad Golshan

Before coming to BU I received a degree in Software Engineering from Tehran University.
I am interested in data mining and artificial intelligence. I also love music — I play violin, and I try to compose simple melodies as a hobby.

Charalampos (Harry)

I work with George Kollios

Natali Ruchansky

After receiving a degree in Mathematics and Computer Science at BU, I decided to stay and pursue a PhD. I’m interested in the algorithmic aspects of data mining, graph theory, mathematics, and networks. I also have a deep love of art – drawing, painting, and photography.

Haohan Zhu

I attended Tsinghua University and the Chinese Academy of Science where I earned (respectively) received B.E in Electronic Science and Technology and M.E in Computer Science and Technology.
My advisor is George Kollios and my interests are time-series data analysis, sequence data analysis, data mining algorithms, database management, and database querying and indexing
