Dr. Dirksen directs a multi-disciplinary research program focused on elucidating disease mechanisms and advancing treatment for muscular dystrophy and heart disease. The laboratory investigates the pathophysiological mechanisms by which defects in the proper control of intracellular calcium signaling lead to muscle dysfunction and disease. Current projects involve elucidating the cellular mechanisms by which muscle function is controlled by proteins involved in coordinating: 1) excitation-contraction coupling, 2) store-operated calcium entry, and 3) mitochondrial calcium uptake and energy production, as well as 4) the molecular mechanisms for skeletal and cardiac muscle dysfunction in myotonic dystrophy.
