Nicole Crown is an Assistant Professor in the Department of Biology at Case Western Reserve University, Cleveland, Ohio. Her research laboratory (Crown Lab) operates within the Department of Biology, with office location in Millis Hall 112 and contact details knc38@case.edu / 216-368-2206. The lab maintains an active research website at http://www.crownlab.science/ focusing on fundamental chromosome dynamics during meiosis.
Dr. Crown's research program investigates the molecular regulation of meiotic chromosome behavior in Drosophila melanogaster, specifically examining how nuclear ecosystems integrate developmental and environmental cues to control chromatin states, 3D chromosome architecture, and segregation mechanics. Her work centers on the critical decision-making process that selects specific DNA double-strand breaks for repair as crossovers—ensuring accurate homologous chromosome segregation. The lab employs integrated approaches combining classical Drosophila genetics with whole-genome sequencing technologies to dissect recombination mechanisms.
Recent publications (2021-2024) reveal consistent thematic focus on meiotic recombination regulation, with significant contributions to understanding genetic background effects, chromosomal inversion impacts, and DNA repair pathway functions in crossover formation. Her work extends into evolutionary genomics through phylogenomic analyses of Drosophila species and thermal adaptation studies in range-expanding populations.
The Crown Lab utilizes Drosophila as a primary model system to address fundamental questions in chromosome biology, with research implications spanning genomic stability, evolutionary processes, and meiotic error prevention. Current investigations continue to explore the molecular machinery governing crossover designation and the spatial organization of chromosomes during cell division.
