Mechanobiology has been the common theme throughout Dr. Irianto research career. His graduate work looked at the consequence of osmotic challenge on chondrocytes. He discovered that alterations in osmolality leads to changes in chromosome condensation state that dictate nuclear enzymes accessibility and translates to changes in transcription as measured by microarray. For Dr. Irianto's postdoctoral work, still focusing on mechanobiology, he entered the cancer biology field by studying the consequence of constrictions in cancer cell migration. Here, he showed that constricted migration of an osteosarcoma line causes damages to the nucleus and DNA, followed by lasting and inheritable genomic, transcriptomic and phenotypic changes, which may contribute to the inter/intra tumor heterogeneity observed in the disease. In 2018, Dr. Irianto joined Department of Biomedical Sciences, Florida State University College of Medicine.
