Dr. Xiao serves as an Assistant Professor of Surgery at Massachusetts General Hospital and Harvard Medical School. Dr. Xiao is internationally recognized in the field of Computational Genomics in Surgery and Medicine. He develops genomics tools and computational methods that can be widely applicable in clinical studies, study the human immuno-metabolic response in disease, and develop innovative approaches to address these challenges and to help translate genomic studies of patients to better disease diagnosis, prevention and therapeutics.

His area of expertise is in knowledge based analysis for the interpretation and integration of genomic data and computation to translate genome technologies to clinical research. For high-throughput, cost-effective analyses of human transcriptome in large scale patient studies, he developed the most comprehensive GeneChip to date (in collaboration with Affymetrix and Wing Wong). Comparing with RNA-sequencing (RNA-seq) data, the array is shown to be highly reproducible in estimating expression at both gene and exon levels and reliable in detection of alternative splicing. In collaboration with Dr. Ron Davis and Stanford Genome Technology Center, we have developed bioinformatic and statistical tools for data analysis, especially for alternative splicing. This platform has been made commercially available by Affymetrix and used in multiple clinical studies by different groups. We further evaluated the performance of the array as part of the FDA Sequencing Quality Control (SEQC) Consortium, and developing approaches to improve and apply RNA-seq and arrays in combination to large-scale clinical studies.
