Nicolas Addington

Nicolas Addington is an Associate Professor and Associate Department Head & Director of Undergraduate Studies in the Department of Mathematics at the University of Oregon, College of Arts and Sciences. His research focuses on algebraic geometry, with particular emphasis on derived categories, Calabi-Yau manifolds, K3 surfaces, and Brauer groups. He explores topics such as Hodge theory, moduli spaces, and arithmetic geometry, often intersecting with homological algebra and representation theory.

His work frequently investigates connections between algebraic structures and geometric properties, including derived equivalences, Fourier-Mukai transforms, and categorical actions. He has contributed to understanding rationality problems in algebraic varieties and the behavior of Hodge numbers in positive characteristic.

Addington’s research also addresses arithmetic aspects, such as Brauer-Manin obstructions to weak approximation on Calabi-Yau threefolds. His publications reflect a deep engagement with both classical geometric questions and modern categorical methods, often leveraging computational tools like K3nCones to explore geometric algorithms.

He is affiliated with the Department of Mathematics and maintains an active research profile, with a focus on mentoring undergraduate and graduate students in algebraic geometry and related fields.
