Research Overview

Mitochondria, essential organelles in eukaryotic cells, play central roles in energy production, metabolic processes, cellular signaling, and many processes related to health, disease, and aging. Since mitochondria are only generated by growth and division of preexisting mitochondria or require them as templates, mitochondrial growth relies on precise import and synthesis of their resident proteins and lipids. The cell thus has a sophisticated system to achieve efficient protein and lipid transport into mitochondria, quality control and coordination of mitochondrial functions with other organelles. We are studying the mechanisms of how the cell makes mitochondria and how the it maintains mitochondrial structures and functions by taking divergent approaches covering molecular genetics, biochemistry, cell biology, and structural biology.
