Genome Stability Lab (GSL)
Research in the group aims to better understand how cells maintain stable genomes and how genomically instable cancers can be detected and targeted in novel ways. Specifically, we are working on the following topics that in the longer term have potential to lead to improved strategies of preventing and treating diseases of unmet need.
1. How do ubiquitylation pathways regulate the DNA damage response and associated processes? To address this question we are integrating cell biology, biochemistry, bioinformatics and high through-put/high-content quantitative microscopy/microarray techniques. The importance of ubiquitylation and DNA damage response pathways is illustrated by the fact that a declining ubiquitin system and accumulating DNA damage can give rise to various human disorders such as cancer and neurodegenerative diseases.
2. Ovarian cancer displays rampant genomic instability and has low long-term survival rates with less than 30 percent of women outliving the disease for more than ten years, mainly due to a lack of early detection methods. We are integrating cutting-edge nanotechnology, cell biology, molecular biology, biochemistry and advanced microscopy methods to develop innovative bio-hybrid drug-delivery vehicles to detect and target early ovarian cancer lesions arising inside the fallopian tube.
