Rebecca Heald, PhD


Andy Lane, PhD

Andy is studying changes in chromosome biology throughout Xenopus embryonic development using CRISPR imaging libraries.

Chris Brownlee, PhD

Chris is interested in how the surface area to volume ratio of the cell controls mitotic spindle architecture.


Lauren Slevin, PhD

Lauren is interested in how spindle assembly factors modulate microtubule nucleation activity and spindle morphology.

Romain Gibeaux, PhD

Romain uses Xenopus hybrids to investigate the consequence of hybridization on fundamental biological mechanisms including size scaling and mitosis.

Xiao Zhou, PhD

Xiao recently joined the lab!


Mina Sun, PhD

Mina is a joint postdoc between the Heald and Bustamante labs working at the interface of in vitro cell biology and single-molecule biophysics.



Andrew Grenfell

Andrew is interested in the function of mitotically relevant noncoding RNAs. He is also developing automated approaches to analyze the Xenopus egg extract spindle.

Kelly Miller

Kelly is broadly interested in mechanisms of cell division and size control in amphibians, most recently using the small pipid Hymenochirus boettgeri.
