My research is in the broad areas of network security and traffic
control, and their intersection. Specific problems of interest include
- Worm epidemics - mathematical epidemic models,
quarantine, rate control, early detection
- Intrusion detection - traffic analysis, packet tracing,
sensor fusion
- Phishing - social engineering, email filtering by machine
learning, email analysis by pattern recognition
- Measurement-based traffic control - traffic modeling,
model classification, machine learning, Bayesian classification
