Dr. Xiuqing Guo is an Assistant Director, Mathematical Genetics at Cedars-Sinai Medical Genetics Institute and an Associate Professor of Pediatrics with expertise in genomic studies and genetic epidemiology. Her research interests have been in pure methodology development to address basic mathematical and biostatistical problems; in solving problems related to gene mapping studies, especially for complex diseases; and data analysis of genetic epidemiologic studies of common, genetically complex diseases, with an emphasis on cardiovascular and metabolic diseases. With the rapid development of molecular techniques, it has become more and more challenging and motivating to develop better statistical methods and apply the appropriate methods to the relevant problem of elucidating the underlying genes for common genetic complex diseases. As an example of Dr. Guo's theoretical work, continuing with early methodology development work in two-stage global search designs for linkage studies, she has recently been working on the methodology development for large scale association studies. She has proposed an Iterative Bayesian Variable Selection Method for analyzing binary traits when sample size is much smaller than number of variables, as is the case in genome-wide association studies. As examples of data analysis, she has led the IRAS Family statistical analyses of the Cedars-Sinai site, including serving as the lead on the linkage analysis of our adiponectin data, and she serves as the lead analyst for all MESA statistical analyses at Cedars-Sinai, including serving as the lead analyst for a number of MESA SHARe working groups such as blood pressure, diabetes and metabolic syndrome, and left ventricular structure and function. Dr. Guo's role on the Biostatistics, Study Design and Clinical Data Management Program (BSD-CDM) will be to develop novel statistical applications and methodologies to address the complexities of biological data and the challenges of community-based research, specifically in High-throughput biological data analysis research.
