Leman Akoglu

Assistant Professor of Information Systems





Data Analytics Techniques Algorithms (DATA) Lab


Our group is interested in
  • understanding, modeling, and leveraging data,
  • that is large-scale, streaming, multi-modal, and/or noisy,
  • toward solving real-world problems,
  • through effective and scalable computational methods,
  • with implications on policy and decision making.
We specifically focus on identifying trends and patterns and in turn rare, anomalous, fraudulent, and/or emerging events.

Our current projects include:
  • Formalizing anomaly problems for complex data
  • Anomaly detection in large complex graphs
  • Fraud detection (opinion spam, credit card fraud, medical fraud, etc.)
  • Analysis and algorithm design for heterogeneous graphs
  • Vulnerability and resilience in large dynamic graphs
  • Analysis of online social media
