MERG is a research group in the department of Mathematics at Colorado State University, focusing on research related to enumerative and combinatorial aspects of the geometry of various moduli spaces. Some of the topics of interest to the group include:

• Gromov-Witten theory and related curve counting theories

• Schubert calculus

• Intersection theory of moduli spaces of curves

• Tropical and logarithmic geometry

• Birational geometry and derived categories
