**About the Editor**

**Liang-Jun Yan** is a professor in the Department of Pharmaceutical Sciences, College of Pharmacy at the University of North Texas Health Science Center. He completed his B.S. in Biochemistry at Peking University and earned his Ph.D. in Molecular and Cell Biology from the University of California at Berkeley. His research has centered on redox imbalance and mitochondrial oxidative stress in aging and age-related metabolic disease. His lab is currently working on kidney disease, in particular, ischemia- and drug-induced acute kidney injury and chronic diabetic kidney disease. The objective of these investigations is to elucidate the mechanisms of mitochondrial oxidative stress and redox dysregulation in kidney diseases and to identify novel redox-associated targets for developing potential therapeutics. Relevant to these studies, his group is also interested in studying the therapeutic values of natural products derived from plants and herbs that can be used to fight kidney disease.
