Research Interests

The primary focus of my lab is to examine biophysical processes that govern the self-assembly of the mitotic spindle, a macromolecular machine that segregates chromosomes in a dividing cell, using optical microscopy and computational modeling. Investigations into the biophysics of mitotic spindle assembly would help us understand how proteins, DNA, and other biomolecules self-organize themselves into living, self-replicating cells. Such investigations may also lead to a new cancer therapy since a disruption of the mitotic spindle assembly is an effective way to treat cancer.
