In 1974, Dr. Shih joined the School of Pharmacy faculty at USC.
Dr. Shih has received numerous honors. She received two Research Scientist Awards and two MERIT awards from the National Institutes of Health (NIH), each providing a 10-year support to investigators whose research competence and productivity are distinctly superior and who are likely to continue to perform in an outstanding manner. The MERIT award is given to the top 1% investigators of the country.
Dr. Shih is a Fellow of the American College of Neuropsychopharmacology; a Fellow of Academia Sinica, Taiwan; a recipient of the Volwiler Research Achievement Award from the American Association of Colleges of Pharmacy (AACP); a Distinguish Series Kaiser Lecturer and the USC Associates Award for Creativity in Research and Scholarship; among many others.
She is a member of the NIH study sections (Psycho Clinical Biology, 1984-88; Neurobiology, 1990-94; NICHD Mental Retardation Committee, 1997-2001). She is also a member of the International Brain Research Committee of the National Academy of Sciences (1995-present). She is a current member and past president of the Society of Chinese Bioscientists in America.
Research Field:
My research objectives are to understand the functions of monoamine neurotransmitters on transcriptional regulation of gene expression, signally transduction pathways and ultimately to behaviors. These studies will not only provide new knowledge on the molecular mechanisms of brain functions but also help us understand the molecular basis of mental disorders such as bipolar depression, schizophrenia, Alzheimer's and Parkinson's diseases.
This information will be useful for designing novel therapeutic agents and early diagnosis of these diseases.
Our research projects are focused on the regulation, structure and functions of monoamine oxidase isoenzymes and serotonin receptors. We are currently using DNA chips, proteomics and bioinformatic approaches to study the role of serotonin in the regulation of transcription factors and other gene expression in a series of MAO gene knock-out and transgenic mice, which exhibit different behaviors including anxiety and aggression. This information will be linked to human databases and help identify polymorphism and SNP in genes related to mental disorders.
