Katharine Dibb

Dr. Katharine Dibb is Senior Lecturer in Cardiovascular Sciences at the University of Manchester, where she leads research on atrial cellular structure and function. Her work focuses on transverse (t)-tubule networks in cardiac atria and their role in health and disease.

Research examines:

• T-tubule plasticity in heart failure and recovery
• Calcium handling mechanisms in aging atria
• Cellular substrates for atrial fibrillation
• Dysferlin's role in striated muscle function

Her group demonstrated t-tubule loss in heart failure and subsequent disordered restoration, with functional implications for calcium signaling. Current projects investigate how t-tubule architecture influences arrhythmia susceptibility in aging and disease.

Methodological expertise includes patch-clamp electrophysiology, confocal/super-resolution imaging, and intracellular ion measurement. She serves on editorial boards for Journal of Molecular and Cellular Cardiology and Physiological Reports, and reviews for British Heart Foundation grants.
