Research Interests:

Molecular Genetics
Reactive Oxygen Species

Working as part of a collaborative team including clinicians, geneticists, and bioinformaticians, we are identifying mutations responsible for rare genetic disorders, including rare cancers.  We use a combination of techniques including genotyping, genetic mapping, sequencing and Q-RT-PCR to identify the underlying genetic mutations.  Our lab uses human cell culture models to study the impact of identified genetic variations on the function of particular genes, with a particular interest in the role of reactive oxygen species.

Involvement with BHCRI to date:
