Research Interests
Our laboratory studies how telomeres, the chromosomal termini, are kept intact. We are exploring how the telomerase RNA, which supplies the template for the synthesis of telomeric DNA, functions in regulating telomere length. Without this RNA, telomeres get shorter and this can contribute to cellular aging. Our research is conducted in model organisms that are quick to reproduce and easy to use, like the filamentous fungus Aspergillus, and thus are great for undergraduates.
