Dr. Chiu is an expert in the development and implementation of advanced genomic technologies for pathogen discovery and clinical diagnostics, including microarrays and next-generation sequencing, for a variety of blood-borne infections. His efforts in Lyme disease focus on the development of diagnostics for both pathogen detection and host response. He uses next-generation sequencing and has developed the “TickChip” to directly detect the RNA of Lyme bacteria and other tick-borne pathogens. He is also using RNA-sequencing technology to detect and identify a diagnostic profile of the body’s response to being infected by Lyme disease. He recently published in the highly prestigious New England Journal of Medicine, as described in a New York Times article, about the ability to uniquely and expeditiously diagnose a disease caused by a bacteria that is in the same family as Lyme disease.
Genomic Approaches for Pathogen and Infectious Disease Diagnosis
Identification of genetic signatures for pathogens in clinical samples is a promising approach for the diagnosis, management, and treatment of patients with unknown infections. The potential and pitfalls of emerging genomic technologies for infectious disease diagnostics — metagenomics, real-time nanopore sequencing, probe-based sequence enrichment, and human host transcriptome profiling — will be discussed.
