My areas of research are free-radical biology, toxicology and apoptosis. The major aim of my study is to investigate the cellular mechanisms of potential natural products, chemicals, or toxic substances on cellular oxidative condition.

In 2013, I was awarded a M.Sc. from the Department of Medicinal Chemistry and Molecular Pharmacology, Purdue University. My research project, supervised by Dr. Tony Hazbun, was mainly focused on chromatin biology of the centromere. 

I was a Royal Thai Government Scholarship’s student, so after graduation I returned to my homeland and now work for the Thai government as an instructor and researcher in the Department of Pharmacology and Physiology, Faculty of Pharmaceutical Sciences, Chulalongkorn University, where I utilize my toxicology knowledge not only to educate and develop the students who will one day become the future of my country, but also to do research to develop a risk assessment monitoring system for pharmaceutical and chemical products in Thailand.
