Research Interest:

Currently, I am interested in understanding the wide variety of regulatory mechanisms that promote cancer development and metastasis. My previous research has focused on identifying mechanosensitive proteins that can potentially alter gene expression by shuttling into the nucleus depending on the stiffness of the cellular environment. Additionally, I worked on elucidating the structural landscape of F-actin under different nucleotide states in order to better understand how interactions between F-actin and actin binding proteins are regulated to transduce mechanical forces into biochemical signaling cascades.
