Research Interest Summary

Heart muscle cell development and regeneration

Research Categories

Research Interests

My research is on the century-old question of whether and to what extent mammalian hearts can regenerate themselves, which is directly related to heart failure, a significant public health problem worldwide. My approach involves basic and translational research and is synergistic with my clinical interest in heart muscle diseases (cardiomyopathy).

My research has three interconnected goals: to understand the mechanisms of cellular growth and proliferation in the heart; to provide mechanistic explanations for the huge variation of regenerative activity seen in biology; and, drawing on the answers to these two fundamental questions, to conduct translational research that implements our basic research results for the diagnosis and treatment of heart failure.
