Alex Suciu

Background

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.

Research

My research interests are in Topology, and how it relates to Algebra, Geometry, and Combinatorics. I mainly study hyperplane arrangements, cohomology jumping loci, and generalized moment angle complexes. I also study various problems concerning the topology and geometry of knots, links, and manifolds, and the homology and lower central series of discrete groups. Below are some recent papers and preprints (click here for a complete list).

Teaching

I teach a variety of math courses, both at the undergraduate and graduate level. If you are interested in taking a directed study course or a reading course with me (in addition to those courses regularly offered), please contact me.

In Spring 2009, I taught graduate courses in Topology 1 and Topology 3.
In Spring 2010, I taught an undergraduate course in Topology, and graduate courses in Topology 2 and Topics in Topology.
In Fall 2010, I teach two sections of MATH3175, an undergraduate course in Group Theory.

Activities

In May-June, 2009, I visited the University of Nice, where I attended a workshop on Fundamental Groups in Algebraic Geometry. At the end of June, I was in Jaca, Spain for the LIB60BER Conference on the Topology of Algebraic Varieties. In August, I was at Hokkaido University in Sapporo, for the MSJ Seasonal Institute on Arrangements of Hyperplanes. In Fall, 2009 I visited the University of Warwick and VU University Amsterdam.
In May-June, 2010, I visited the Centro di Ricerca Matematica Ennio De Giorgi, in Pisa, Italy, where I attended an intensive research period on Configuration Spaces: Geometry, Combinatorics and Topology.
