Research Interests

I am investigating the role of the Drosophila BLM protein in the early embryo. BLM is a DNA helicase that acts to prevent mitotic crossover and can resolve problematic replication forks during DNA replication. BLM is essential in early embryonic development; there is a requirement for maternally loaded BLM prior to the start of zygotic transcription. Therefore, BLM mutant females have a high rate of sterility and the embryos from these mutant mothers show severe nuclear defects. I am exploring whether BLM functions to prevent replication fork problems during the rapid DNA replication cycles in the early Drosophila embryo.

Additionally, I am a SPIRE Postdoctoral Scholar and am teaching courses at North Carolina Central University in Introductory Biology and a special topics course on Model Systems in Biomedical and Cancer Research as a part of the SPIRE Fellowship training program.
