About the Lab

Proper contraction and relaxation of the heart depends on the coordinated flux of calcium ions in and out of individual cardiac muscle cells. Research in our lab focuses on understanding how these calcium dynamics are regulated in normal and diseased hearts, and how abnormal intracellular calcium release may contribute to the development of cardiac arrhythmias, hypertrophy and heart failure.

We are particularly interested in the genetic and posttranslational regulation of key molecules involved in intracellular calcium handling, including the ryanodine receptor type 2 (RyR2), striated muscle preferentially expressed protein kinase (SPEG), and junctophilin-2 (JPH2).  

Current major projects in the lab focus on the molecular basis of inherited arrhythmia syndromes like catecholaminergic polymorphic ventricular tachycardia, long QT syndrome and Wolff-Parkinson-White syndrome as well as other more complex, multifactorial cardiac diseases like atrial fibrillation and hypertrophic cardiomyopathy. These translational studies are aimed at developing new therapeutic targets for heart disease.
