Profile Introduction

I develop mathematical and computational methods to address questions that arise in the study of the 3D structure of chromosomes. The three dimensional (3D) structure of the genome plays a key role in the dynamics of the living cell tightly regulating essential biological processes such as transcription, replication and repair. In humans, disruption of the 3D structure of the genome, in the form of large-scale rearrangements and copy number changes, is the signature of DNA-damaging agents and has been associated with a wide range of diseases, including cancer. In parasitic organisms, the 3D structure of the genome is a frequent drug target. Descriptions of the 3D structure genomes however have remained elusive even for the simplest organism.

In our most recent research we are developing new mathematical methods to characterize the packing of DNA in: dsDNA bacteriophages, mitochondrial DNA in trypanosomes (kDNA) and yeast.
