# Research Interests

My main focus lies in extending the parameterized complexity paradigm to new domains, especially to non-discrete problems such as clustering. I enjoy coupling combinatorial tools with randomized/approximate/algebraic techniques. My main topics include:

- Parameterized algorithms
- Approximation algorithms
- Graph theory
- Learning theory
