Alexandru I. Suciu

Professor of Mathematics
Northeastern University

I hail from Bucharest, Romania. I did my undergraduate studies at the Faculty of Mathematics of the University of Bucharest. Here is a picture from those days. For my graduate studies, I went to Columbia University, receiving my Ph.D. degree in 1984. Here is a picture from around that time, taken in Cambridge, UK. After a J.W. Gibbs Instructorship at Yale University, I came in 1986 to Northeastern University, where I’ve been ever since.

My research interests are in Topology, and how it relates to Algebra, Geometry, and Combinatorics. I currently investigate cohomology jumping loci, and their applications to algebraic varieties, low-dimensional topology, and toric topology, such as the study of hyperplane arrangements, Milnor fibrations, moment angle complexes, configuration spaces, and various classes of knots, links, and manifolds, as well as the homology and lower central series of discrete groups.

  • In Fall 2021, I taught MATH 4565, an undergraduate course in Topology.
  • In Spring 2022, I taught MATH 7721, a Readings in Topology course.
  • In Summer-2 2022, I taught MATH 3175, an undergraduate course in Group Theory.
  • In Fall 2022, I taught MATH 3150, an undergraduate course in Real Analysis, and MATH 4565, an undergraduate course in Topology.
