Research Interests

Impact of nuclear structure on the generation of pathogenic rearrangements

My research interests are centered on mechanisms driving DNA aberration formation. These may lead to both neoplastic changes such as leukemia’s and solid tumors as well as lethal changes that kill the cell. Radiation is used in the treament of most solid tumors and the organization and orientation of the whole genome will impact how lethal lesiuons are generated.  Such alterations are being studied using both conventional molecular biology tools as well as array technology and massively parallel sequencing.
