Hong Gu, Ph.D.

Research Associate | honggu@mail.nih.gov

Dr. Gu received her B.S. (1993) and M.S. (1996) in Electronic Engineering at Hefei University of Technology and University of Science and Technology of China, respectively. She received her Ph.D. in Biomedical Engineering from Shanghai Jiao Tong University, China in 2000. She then went on to postdoctoral associate position from 2000 to 2003 in the Functional Neuroimaging Laboratory at Weill Medical College of Cornell University in New York City. In 2003, she joined the Neuroimaging Research Branch at the National Institute on Drug Abuse (NIDA) as a research associate. Her research interests focus on the development and application of functional magnetic resonance imaging (fMRI) and functional connectivity MRI methodologies.

Projects:

  • Development of reesting-state functional connectivity analysis methods
  • Development of simultaneous VASO, perfusion, and BOLD imaging techniques
  • Development of efficient fMRI imaging techniques to reduce susceptibility artifacts
  • Application of novel data analysis methods to fMRI data
