Dr. Xiao Hu is a Professor at the Nell Hodgson Woodruff School of Nursing, an associated professor at department of Computer Sciences at College of Arts and Sciences and a program faculty member of the joint GA Tech and Emory Biomedical Engineering department. Dr. Hu is also the Associate Director of the Center for Data Science. Dr. Hu earned bachelor’s and master’s of science degrees in biomedical engineering at the University of Electronic Science and Technology in Chengdu, China. He then studied at UCLA, receiving a PhD in biomedical engineering in 2004. Before joining Emory, he held faculty positions at UCLA, UCSF, and Duke University.

Hu conducts research at the intersection of computational and health sciences where he develops signal processing, mathematical modeling, machine learning, and deep learning algorithms to transform physiological and clinical data into actionable information for improving patient care. Through his research, Hu has created knowledge advancing the relationship among clinicians, scientists, engineers, innovators, policy makers, and healthcare administrators.

Hu is the current editor-in-chief for Physiological Measurement and an associate editor of an inaugural Taylor and Francis journal, Brain-Apparatus Communication: A Journal of Bacomics. He has over 220 peer-reviewed journal publications. Hu has been a principal investigator on seven NIH R01, three NIH R21 research projects, and several industrial grants. He is a multiple PI for the CHoRUS project under NIH’s Bridge2AI program Additionally, Hu holds nine US patents.
