Xiaoling (aka Ling) was born in Shanghai and grew up in Beijing, China. She came to US in 1983 after obtaining her Bachelor of Science degree in Northwest Agriculture University in China. Her first stop in the US was the University of Kentucky. After her MS degree, she wanted to explore the new frontier of molecular biology, so went to study at Cornell University in upstate New York for her Ph.D. in Plant Pathology with focus on fungal molecular biology and genetics. After her postdoctoral fellowship in fungal molecular genetics in the Infectious Diseases at Eli Lilly and Company, she worked as a biochemist, and later as a senior biochemist, in initial drug discovery in the PPR&D at Abbott Labs from 1994 to 2001. She returned to academics in 2002 to join the faculty of Indiana University School of Medicine as an associate research professor, then full research professor. Her area of interest includes human genetics and genomics, specifically applying genomics technologies of SNP genotyping, microarray and next-gen sequencing to the area of genetics of alcoholism and other common complex disorders.

    Ling's main function is as technical director in the Center for Medical Genomics at IUSM. The Center for Medical Genomics is a multi-functional genomics center facilitated with Illumina HiSeq 4000, Illumina NextSeq 500, Life Technologies Ion Proton Sequencer, Sequenom MassARRAY, and Affymetrix GeneChip Array for Next-Gen sequencing, SNP genotyping, allele-specific expression, targeted methylation, and gene expression microarray. The center serves as the core for genomics research on campus as well as off campus.

    In addition, Ling has been involved in the multi-institutional collaborative studies on genetics of alcoholism (COGA) for more than 15 years. The major research focus of COGA involves searching for genes responsible for alcoholism using family-based strategy, and studying the potential functions of the genes discovered through genetic analysis.
