About
I am a postdoctoral researcher in the Fly Logistics Unit at Linköping University, working with Valentin Polishchuk and Christiane Schmidt . I received my PhD in 2023 from Stony Brook University, advised by Joseph S. B. Mitchell.
My research is in computational geometry, from structural and complexity-theoretic questions about geometric optimization to applications in air traffic management, drone logistics, and reliability measures for machine learning.
My CV.
Research interests
- Visibility and guarding: art gallery variants.
- Geometric algorithms and complexity: approximation algorithms, NP-hardness, algberaic hardness.
- Motion planning: watchman route, domain sweeping.
- Air and drone traffic: optimization in air traffic management, geometric data analysis for infrastructure designs.
- Geometry for ML reliability: applying geometric tools for reliability of ML models.
