My work is centered on homological algebra, which is essentially the study of “linearized scaffolds of spaces”: chain complexes, (co)homology and so on. In some sense, homological algebra is “higher dimensional linear algebra”. I’m mostly interested in the theory and applications of differential graded (=dg) categories, which are categories whose hom-sets are themselves chain complexes. Dg-categories are, in fact, part of the world of higher categories, and they serve as enhancements for triangulated categories - a common tool in contemporary algebra and algebraic geometry.
