Rebecca Heald

Rebecca Heald is a Professor of Cell Biology at the University of California, Berkeley, in the Department of BIO. Her research focuses on cell division and size control, utilizing in vitro systems such as cytoplasmic extracts from Xenopus laevis eggs to study mitotic chromosome condensation, spindle assembly, and function. Her work also explores interspecies scaling and developmental scaling using Xenopus tropicalis and embryonic extracts. Heald's research provides insights into fundamental biological processes essential for development and disease, with a focus on mechanisms underlying spindle assembly and size regulation.

Rebecca Heald is a cell biologist whose research focuses on cell division, biological size control, and the mechanisms underlying mitotic spindle assembly. Her work explores how microtubules organize into bipolar spindles, the role of Ran-GTP gradients in spindle positioning, and the molecular interactions that regulate nuclear lamina disassembly during mitosis. Heald's studies also examine the functions of importin β, dynein/dynactin complexes, and NuMA in spindle formation. Her research integrates Xenopus egg extracts to dissect the dynamics of spindle assembly and cytokinesis, shedding light on the conserved mechanisms of cell division across species.
