 Mission

Welcome to Dr. Cheng’s Lab! We are dedicated to a better understanding of metabolic disorders and to developing mechanism-driven therapeutic rationales for human metabolic diseases (e.g., diabetes, obesity, and cancer). To make a lasting impact in this field, we are motivated to conduct well-designed studies leading to exciting and novel discoveries. Here in the Cheng Lab, you will enjoy great team work and good scholarship. All lab members are expected to work individually, collaboratively, and supportively. Our priority is that you are happy in the lab and enjoy science and discovery, so you can be productive and well prepared for the future career.


 Projects

Metabolic diseases have become a global health issue to date. Previous studies have suggested genetic and environmental factors, as well as gene-environment interactions (epigenetics), are significantly associated with metabolic disorders. As the primary metabolic platform, mitochondria show various defects in individuals with metabolic diseases (e.g., diabetes, obesity, and cancer). How genetic, epigenetic and environmental factors regulate mitochondrial function is the topic of intensive research in our lab. The ongoing projects include: (1) genetic and epigenetic regulation of mitochondrial function and metabolic reprogramming, (2) the redox role of mitochondria in regulating nutrient and energy homeostasis, and (3) nutritional solutions to mitochondrial dysfunction and metabolic diseases. We employ interdisciplinary techniques and foster a broad collaboration with the research laboratories of chemistry, biochemistry, molecular and cellular biology, genetics, and bioinformatics.
