I am an assistant professor in the
Department of Computer Science at Stony Brook University.
My research interests are broadly in
data mining, graph mining, machine learning, and social media analysis.
I primarily focus on pattern mining, anomaly and event detection in large, time-varying graphs
using scalable algorithms and tools.
For recent projects, see our DATA Lab group page.
I am looking for highly (self-) motivated and hardworking Ph.D. students who are passionate in data mining research.
to Stony Brook University graduate program, if you are interested in joining our group.
Large-scale graph mining
Anomaly, event, and fraud detection
Applied machine learning
Social and information media analysis
I got my
Ph.D. from the Computer Science Department at
Carnegie Mellon University in Aug. 2012 (I defended this).
I was extremely fortunate to have Prof. Christos Faloutsos
as my Ph.D. advisor.
During my doctoral studies, I also worked at IBM T. J. Watson Research
Labs (two summers) and Microsoft Research at Redmond (one summer).
I hold a B.S. in Computer Science from Bilkent University, where
I was fortunate to be advised by Prof. Ozgur Ulusoy.
