I am a landed immigrant in Canada since 2001 working with Dr. Yeomans. I did my MD in Hebei Medical University, China, and Ph.D., and Doctoral Degree in Medical Sciences in Tottori University, Japan. I received two year’s postdoctoral training (JSPS, Japan Society For the Promotion of Science) in molecular and cellular biology, and was appointed assistant professor in Biomedical Sciences at Tottori University between 1999-2000, and then took my associate professorship in the Neuroscience Research Institute of Peking University (Beijing, China) between 2000-2002.
I spend much of my time in the lab studying the molecular and cellular mechanisms of reward, drug addiction and schizophrenia that are relevant to dopamine and cholinergic systems. I manage Dr. Yeomans’ research students and projects in these areas. Recently, we put forward the “ACh-Dopamine (M5) Hypothesis of Schizophrenia” (Wang et al., NPP 2004).

CURRENT RESEARCH PROJECTS:
1. Creating M5 transgenic mice and testing the effects of M5 over-expression in reward, drug addiction, learning and memory. We will test whether these mice are more susceptible to drugs of abuse, and animal models of schizophrenia.
2. Creating M5 and D2, M5 and alpha-7 nicotine receptor, and M1 and M5 KO mice to study the interaction of these important genes in rewards, drug addiction, learning and memory. This will help address many interesting questions.
3. Rescue of genes such as M5, D2, and CK-1e in knockout mice and mutant hamsters to study where and how these genes affect rewards, drug addiction and circadian rhythms.

Currently my research interests center around the pharmacology and genetics of brain reward systems. I am particularly interested in how the cholinergic system controls brain dopamine systems and the role that different types of muscarinic cholinergic receptors play in these processes. I am investigating the role of receptor subtypes using pharmacology, gene electroporation, and knock-out mice combined with a number of behavioral paradigms including brain-stimulation reward and conditioned place preference learning.
I am also interested in the role that midbrain cholinergic nuclei (pedunculopontine tegmental nucleus and laterodorsal tegmental nucleus) play in organizing approach and withdrawal behaviors. Cholinergic neurons of these nuclei have both ascending projections that innervate dopamine neurons and descending projections into the brainstem that control defensive startle responses and so are likely important in inhibiting defensive withdrawal responses when the organism is orienting toward/approaching potentially rewarding stimuli in its environment.
