Since 2002, Dr. Chaysavanh Manichanh is using meta-omic approaches to study the human microbiome associated with disorders. In 2006, Chaysavanh joined the VHIR institute in Barcelona as principal investigator to pursue her line of research on Human Microbiome. She has collaborated with the MetaHIT and the IHMS consortia to build a comprehensive gene catalogue from the human gut microbiome and to develop standard operating procedures (SOPs) and protocols in order to optimize data comparisons in the human microbiome field. With this experience and her double expertise in molecular microbiology (PhD University Paris VI, 2001) and in bioinformatics (Degree at Pasteur Institute, Paris 2000), she is leading at VHIR a multidisciplinary research group to develop molecular, cellular as well as bioinformatics tools to understand the role of the microbiome in human health and disease.
