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 currently investigate cohomology jumping loci, and their applications to algebraic varieties, low-dimensional topology, and toric topology, such as the study of hyperplane arrangements, 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. 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 2012, I taught MATH 7722, a Readings in Algebraic Topology course, and MATH 7723, a Readings in Geometric Topology course.
  • In Fall 2012, I taught MATH 7723, a Readings in Geometric Topology course, and MATH 9990, a Dissertation course.
  • In Spring 2013, I taught MATH 2351, an undergraduate course in Ordinary Differential Equations, MATH 5121, a graduate Topology 1 course, MATH 7722, a Readings in Algebraic Topology course, and MATH 9996, a Dissertation Continuation course.
  • In Spring 2014, I taught MATH 4565, an undergraduate course in Topology, and MATH 9996, a Dissertation Continuation course.
  • In Fall 2014, I taught MATH 3150, an undergraduate course in Real Analysis, MATH 7221, a graduate course in Topology 2, and MATH 9996, a Dissertation Continuation course.
  • In Spring 2015, I taught MATH 4970, a Senior Honors Project in Knot Theory, and MATH 9996, a Dissertation Continuation course.
  • In Fall 2015, I will teach MATH 3150, an undergraduate course in Real Analysis, and MATH 5121, a graduate Topology 1 course.

Activities

  • In February, 2012, I attended a workshop on Homotopy Theory and Toric Spaces, at Princeton and Rider universities. In April and May, I visited the Max Planck Institute for Mathematics in Bonn, Germany and attended a workshop on Arrangements and Configuration Spaces at the University of Bremen. In early June I attended a workshop on Singularities of Differential Equations in Algebraic Geometry, at CIRM, Luminy, France, and gave a series of lectures at a school and workshop on Hyperplane Arrangements and Related Topics, held at the University of Pau, France, while in late June I visited IMAR, in Bucharest, Romania. In early October, I organized, together with Graham Denham, a mini-workshop on Cohomology Rings and Fundamental Groups of Hyperplane Arrangements, Wonderful Compactifications, and Real Toric Varieties, at MFO, in Oberwolfach, Germany, while in late Fall I visited the University of Sydney.
  • In June, 2013, I returned to Romania, where I visited IMAR, participated in a conference on Experimental and Theoretical Methods in Algebra, Geometry and Topology, held in Eforie Nord, and co-organized two special sessions at the Joint International Mathematics Meeting of the AMS and the RMS, held in Alba Iulia. In September and October, I visited again MPIM in Bonn, Germany, while in November I participated in a conference on Hyperplane Arrangements and Characteristic Classes, held at RIMS in Kyoto, Japan, and visited Hokkaido University in Sapporo.
  • In April, 2014, I organized together with Graham Denham a focussed research group on Hyperplane Arrangements, Wonderful Compactifications, and Tropicalization at BIRS, in Banff, Alberta, after which I attended a workshop on the Topology and Geometry of Networks and Discrete Metric Spaces at IMA, at the University of Minnesotta. In May-June, I visited Queen's University in Belfast, UK, the University of Pisa in Italy, and the universities of Nice and Caen in France. Later in the summer, I attended a conference on Topology of Torus Actions in Daejeon, Korea, and then a Conference on Configuration Spaces at the Palazzone in Cortona, Italy.
  • In February, 2015 I participated in an intensive research period on Algebraic Topology, Geometric and Combinatorial Group Theory, held at the Centro De Giorgi in Pisa, Italy. From mid-April to mid-May I visited the University of Chicago, while in late May I visited Western University in London, Ontario. In June, I visited IMAR and participated in a congress of Romanian mathematicians, held in Iasi, Romania, while in early July I attended a workshop on Computational Geometric Topology in Arrangement Theory at ICERM, in Providence, RI. In August, I attended a workshop on Combinatorial Constructions in Topology, held at the University of Regina in Saskatchewan, Canada.
