Aging, stem cell differentiation, cancer metastasis, and inflammation rely on progressive changes in metabolism resulting in increased levels of reactive oxygen species. Collectively, the accumulation of these molecules is known as cellular oxidation, and pathological levels are referred to as oxidative stress. Our lab develops systems biology tools for investigating how cellular oxidation influences cellular decisions and intrepretation of cues from the extracellular environment. We are interested in the collective behavior that arises during stem cell differentiation, immune cell responses, or drug treatments from metabolic diversity in individual cells. Because of the numerous biochemical reactions involved, we develop computational models and analytical approaches to understand how complex protein networks are regulated in the presence of reactive oxygen species by changes in activity and/or function of redox-sensitive proteins. Experimentally, we are developing novel high-throughput single cell techniques for the detection and quantification of intracellular oxidation.



We are located in the Wallace H. Coulter Department of Biomedical Engineering administered jointly between Georgia Tech and Emory University School of Medicine. The lab is located on the Georgia Tech campus in the Engineered Biosystems Building.
