Research Interests

Chromosomal abnormalities; Development of novel technologies; Canine genomics

Research Summary

Until recently, my research focused on the chromosomal basis (cytogenetics) of genetic disease. This included research projects on clinical cytogenetics, translocation malsegregation, uniparental disomy and genomic imprinting, mechanisms of chromosomal rearrangements, and development of molecular cytogenetic diagnostic technologies. My laboratory used a variety of chromosomal rearrangements to understand how chromosomes break, stabilize, form translocations, or malsegregate. My research was also concerned with how the genetic imbalance has consequences for the individual and we were involved in identifying genes that cause the phenotypic abnormalities associated with certain chromosomal syndromes.

My current research focus is on the development of high-throughput technologies to advance molecular diagnostics, population genetics of genomic diseases in canines, the identification of novel mutations contributing to inherited diseases in dogs and copy number variation in canines.
