Dr. Chen is interested in solving the genetic puzzles of some major mental disorders such as schizophrenia, autism and mental retardation, so he can help elucidate the pathogenesis of these major mental disorders. He is also interested in studying the molecular mechanism of drugs that affect the mental status, such as psychostimulants and antipsychotic drugs. He hopes he can identify the common pathway of these psychoactive drugs, so he can develop better treatment for patients suffering from severe mental disorders.


Dr. Chen has been engaging in identifying susceptibility genes of schizophrenia using systemic genetic approaches, such as cytogenetic analysis, comparative genome hybridization analysis and case-control association study. He has established a collaborative team consisting of psychiatrists, cytogeneticists, molecular geneticists and statisticians to carry out systematic investigation. Recently, he extends his team to help study the genetic underpinnings of autism and mental retardation by collaborating with child psychiatrists and pediatricians. In addition, he also applies the functional genomics methodology such as microarray analysis of gene expression profiling and proteomics to study molecular mechanism of psychoactive drugs. He has identified several differentially expressed genes in the brain under long-term administration of antipsychotic drugs. These findings may shed some lights on the molecular mechanism of antipsychotic drugs and may help develop new drugs in the future.
