Graduate Students

Harshal Chaudhari

I work with John Byers and Evimaria Terzi. My research motivations are real world problems that can be tackled using techniques from algorithmic data mining and machine learning. Another discipline of my research focuses on problems at the intersection of marketing and computer science, involving empirical studies of large scale web platforms (eg. appstores).

Charalampos (Harry) Mavroforakis

I work with Evimaria Terzi and George Kollios. My research focuses on Graph Mining, Machine Learning, and Database Security. I am also interested in Big Data and Computational Biology.

Sofia Nikolakaki

I am working under the supervision of Prof. Evimaria Terzi. My research focus is algorithmic data mining, networks, and machine learning. I am currently working on problems in network graph mining for urban applications.

Bashir Rastegarpanah

My research interests are in the areas of machine learning, data mining, and network science. Currently, my focus is on characterizing large and complex networks and network dynamics. My PhD research is a joint work with the networking group at BU.

Baichuan Zhou

I’m currently working with Professor George Kollios about probabilistic graph mining.
