Research/Academic Interests

Cellular and molecular mechanisms regulating arterial smooth muscle excitability The main goal of my research team is to understand the mechanisms by which local and global calcium signals regulate excitation-contraction coupling and excitation-transcription coupling in arterial smooth muscle cells during physiological and pathological conditions. To tackle these issues, we employ several state-of-the-art techniques including molecular biology, patch-clamp electrophysiology, and confocal and Total Internal Reflections Fluorescence (TIRF) microscopy.  We are currently interested in determining the mechanisms by which hyperglycemia induces the activation of a novel calcium signaling modality (persistent calcium sparklets) in arterial smooth muscle. We think that activation of this signal contributes to enhanced contractility and arterial dysfunction during diabetes.
