Research Interests

Mitochondria are complex organelles whose dysfunction underlies a broad spectrum of human diseases. Mitochondria house a wide range of metabolic pathways, and are central to apoptosis, ion homeostasis and reactive oxygen species production. Thus, to maintain cellular homeostasis cells must exert careful control over their mitochondrial composition and function.

How do cells custom-build mitochondria to suit their metabolic needs? What mechanisms do cells leverage to efficiently control mitochondrial processes? Which mitochondrial processes are disrupted in diseases and how might these be targeted therapeutically?

Our lab takes a multi-disciplinary approach to investigating these questions. By integrating classic biochemistry, molecular biology and genetics with large-scale proteomics and systems approaches, we aim to elucidate how cells regulate mitochondrial metabolism and establish a customized mitochondrial infrastructure across tissues and in response to a changing cellular environment. Below are current focuses of our lab.
