Dr. Sun received her Ph.D. in 2006 from the National University of Singapore and the Karolinska Institute in Sweden. For her thesis, Dr. Sun worked on the chemotherapeutic resistance in B lymphoma cells, focusing on the apoptotic signaling pathway.  Dr. Sun is currently working on the role of reactive oxygen and nitrogen species (RONS) in cancer control with emphasis on the thioredoxin system.  She is also studying in depth a novel anitcancer peptide, of which she is a co-inventor.
