Yunjie Tong is an Associate Professor of Biomedical Engineering at Purdue University. Originally from Beijing, China, he earned his BS degree in Physics from Beijing University and later pursued his PhD in Biomedical Engineering at Tufts University, focusing his thesis on multimodal functional brain imaging. Dr. Tong has a profound interest in exploring brain function, perfusion, general physiology, and their interactions. He adopts a multimodal imaging approach in his research, utilizing tools such as MRI, Near-infrared Spectroscopy, EEG, and Transcranial Doppler Ultrasound. Alongside his team, Dr. Tong is dedicated to developing innovative experimental and analytical methods for brain imaging. In recent years, his research has extended to investigating neurofluid dynamics in resting states and during sleep, examining hemodynamics in conditions like sickle cell disease, and exploring neurodegenerative diseases including Alzheimer’s disease. He enjoys traveling and is a strong proponent of leveraging biomedical engineering to make a global impact.
