I am a cell biologist and bioengineer studying cell mechanics and mechanotransduction—how mechanical forces regulate cellular function in health and disease.

Cardiovascular disease (CVD) is the leading cause of death worldwide, with arterial stiffness linked to its progression. This stiffening drives aberrant vascular smooth muscle cell (VSMC) migration and proliferation, yet its underlying mechanisms remain unclear. While antihypertensive drugs exist, none specifically target arterial stiffness pathways. My lab aims to clarify how arterial stiffness influences VSMC function and drives CVD progression, focusing on extracellular matrix stiffness and VSMC behavior in vascular remodeling. We use a novel approach combining atomic force microscopy and traction force microscopy to manipulate and measure stiffness, culturing cells on compliant substrates that mimic in vivo mechanics.

Recent advances in genomics, stem cell biology, optogenetics, and biophotonics have enabled precise control of biological processes using light. My lab focuses on developing a nanophotonic platform to regulate gene expression and direct stem cell differentiation in neuronal cells through light-controlled protein-protein interactions. Specifically, we utilize a molecular toggle switch based on Plant Phytochrome B and transcription factor Pif6 to modulate nuclear fibroblast growth factor receptor-1, a master regulator of stem cell differentiation. This approach offers a precise, non-invasive method to manipulate cellular function with high spatial and temporal resolution.
