Recently, I have been interested in scheduling theory and its ties with graph theory in the development of approximation algorithms and computational complexity results. Widely I have interests in algorithmic problems of Theoretical Computer Science and Combinatorial Optimization, with a specific focus at the crossroads of approximation algorithms, scheduling problems, and parameterized complexity. At the present time I am investigating parallel machine scheduling problems, and attempting to further unravel why parallel machine scheduling is so hard. Many of the algorithmic problems I investigate have applications in Operations Research.Degrees
