Research Activities
The research activities in our laboratory involve organic/inorganic chemical synthesis, artificial enzymes including nanozymes, genetic code expansion and other multidisciplinary studies in the area of biomedical research. Our recent efforts are directed toward understanding the redox regulation by synthetic compounds in mammalian cells, thyroid hormone metabolism and thyroid related disorders, development of molecular probes for the detection and quantification of reactive oxygen species in the cells and oxidative stress biomarkers. We have a unique multidisciplinary team for an efficient collaboration within the laboratory and outside to undertake challenging contemporary research problems at the chemistry-biology interface.
