Donggyu is a Bachelor of Biomedical Science graduate from Monash University. During the final year of his undergraduate studies, he undertook a work-integrated learning program at the Australian Regenerative Medicine Institute, after which he continued to complete his Honours degree. After graduating with first class Honours, Donggyu has moved to Baker Heart and Diabetes Institute for his PhD studies, supervised by Professor Vaughan Macefield, Professor Luke Henderson and Associate Professor Elisabeth Lambert.

Donggyu's current work focuses on recording muscle sympathetic nerve activity in concert with imaging the activity of the brain to identify novel brain regions associated with an elevated sympathetic drive in people with high blood pressure. He aims to extend this work to people with cardiovascular diseases such as atrial fibrillation and heart failure.
