I'm interested in discrete structures that appear in mathematics, statistics, and computer science. Particularly, I like problems where all these areas intersect.

- Machine learning and neural networks
- Anomaly detection and time series analysis
- Optimization and random sampling
- Distributed and large-scale computing
- Random walks on combinatorial objects
