Dr. Yijun Liu

Dr. Liu graduated from Shanghai Jiaotong University with a bachelor degree in Biomedical Engineering, and the University of Texas Health Science Center at San Antonio (UTHSCSA) with a doctoral degree in Physiology. He was a Research Fellow in the prestigious Research Imaging Center at UTHSCSA before he joined in the Department of Psychiatry and McKnight Brain Institute at the University of Florida (UF) as an assistant professor. Dr. Liu pioneered research on the sensory function of human red nucleus using functional magnetic resonance imaging (fMRI) techniques. He developed the TCA (temporal clustering analysis) method for dynamic mapping of the brain and first applied this technique to reveal in vivo the hypothalamic response following eating. Dr. Liu and his colleagues at UF conducted a series of fMRI research projects to investigate the neural timing mechanisms involved in various cognitive-affective processes, and to model the functional (or dysfunctional) brain circuitry underlying certain neuropsychiatric illnesses, such as obsessive compulsive disorder (OCD). Dr. Liu is a member of the International Society of Magnetic Resonance in Medicine, the Society for Neuroscience, and the Organization for Human Brain Mapping.

Research and Scholarly Interests

The research interest in Dr. Liu's lab is to develop neuroimaging methods for both basic neuroscience study and clinical investigation. In particular, we use functional magnetic resonance imaging (fMRI) to model neural-system circuits mediating various brain functions and disorders. Current work includes:

  • Using fMRI to probe the neuropathological and neuropharmacological bases of certain psychiatric disorders, such as Obsessive-Compulsive Disorder/Tourette's Syndrome, Autism/Abnormal Repetitive Behavior, Schizophrenia, etc., and evaluate the treatment for these diseases
  • Development of in vivo neural-system modeling methods to explore the role of subcortical structures (e.g., the thalamus, basal ganglia, midbrain, and cerebellum) in the perceptual and adaptive processes underlying human cognition and affection, and especially, in the maintenance of our (self-)consciousness
  • Approaches to the real timing of brain-hormone interaction, e.g., an fMRI model of hypothalamic function in the control of feeding behavior (for the further study of obesity, diabetes, drinking and gambling problems, and eating disorders in humans)
  • A Dynamic Brain Mapping program using the real-time fMRI techniques, with integration of recent development in MR phase imaging, perfusion imaging, and diffusion imaging

Educational Interests and Accomplishments

Dr. Liu's lab provides training for both undergraduate and graduate students, and for postdoctoral fellows (including residents) with background in physical and biological sciences. The training is focused on the basic skills of functional brain mapping, MRI physics and applications, paradigm designs for both neurophysiological and behavioral experiments, computer programming and biomedical image processing. Currently, this lab is not directly involved in class teaching. The educational accomplishments are primarily through other formats such as presenting seminars and supervising theses. The following people have been actively involved in the training provided in this lab:

  • Guojun He, Ph.D., Research Associate, Lab manager
  • Nelson Klahr, B.S., Ph.D. graduate student in the Interdisciplinary Program in Biomedical Sciences in the UF College of Medicine
Former labmembers:
  • Jessica A Couch, Ph. D., Postdoctoral Fellow (now in a biological corporation in Boston)
  • Paul Wright, B.S., Ph.D., Graduate Student (now in England)
  • Chaoyong Bai, VMD, Postdoctoral Fellow (now in China)
  • G. Andrew James, Ph. D.Graduate Student (now working in the Department of Biomedical Engineering at Emory University)
  • Jaclyn Wetherington, Graduate research assistant
  • Martin Repetto, M.D./Ph.D., Resident in Psychiatry
  • Yasmine Taeb, Undergraduate student in the UF Interdisciplinary Scholar (IDS) Program

Leadership and Service

Dr. Liu helped Dr. William Luttge in the development of a National Center for Human Brain Functional Imaging Technology and Image-Guided Surgery (CHBFIT) within the McKnight Brain Institute of the University of Florida.
