Research Interests
My laboratory studies mitochondria, critical cellular organelles that produce most of the cellular energy. Mitochondria are specially equipped to produce chemical energy required for cellular processes. This energy-producing process involves carefully controlled electron transport within mitochondria. However, when this process is perturbed, electrons can uncontrollably react with oxygen molecules to produce oxygen radicals that can be further converted to various highly reactive toxic chemical compounds called reactive oxygen species (ROS). Mitochondria contain elaborately organized internal structures encapsulated in dynamically changing tubular networks. This dynamic shape change is mediated by fission and fusion of membrane tubules. Our research focus is to define the molecular mechanisms of mitochondrial shape change and to understand physiological significance of mitochondrial dynamics. Our studies have found that mitochondrial shape change is a key element participating in regulation of mitochondrial electron transport and ROS production.
