Research Scientist in Epidemiology (Environmental Health Sciences)
Biography
Dr. Chen has a broad background in environmental genetics and molecular toxicology, with specific training and expertise in redox biology, oxidative stress related diseases, and transgenic mouse models of redox dysregulation. Her research over the past ten years utilizes unique animal models and applies the system biology approach integrating multi-omics data and histopathology to understand the mechanistic roles of redox homeostasis in disease conditions related to environmental and dietary exposures.
- How does redox-elicited modifications of the liver proteome tune cellular response to protect against alcohol-associated fatty liver disease?
- Does oxidative stress play a mutagenic role in emerging water contaminant 1,4-dioxane-induced liver cancer
- What is the functional crosstalk between antioxidants in the central nervous system as they relate to neuronal health and disease?
- What is the translational importance of these new knowledge in risk assessment, disease prevention and treatment?

Research
Overview
Dr. Chen’s research focuses on understanding the mechanistic functions of redox homeostasis and antioxidant deficiencies in human diseases associated with environmental and dietary stress. Reduced GSH is the most abundant thiol antioxidant that combats excessive oxidants generated during cellular metabolism or in response to environmental assaults. GSH deficiency has been associated with numerous pathological conditions in human. Dr. Chen’s research work involves the use of unique redox animal models and system biology approach to elucidate the molecular mechanisms underlying liver diseases and neurological disorders.
Specific research projects include:
- Redox-mediated mechanisms in protection against alcohol-associated fatty liver disease
- The mechanistic role of oxidative stress in water contaminant 1,4-dioxane-induced liver cytotoxicity and genotoxicity
- The functional interplay between two antioxidants (glutathione and ascorbate) in the central nervous system
