I am professor of neurology at UCSF and a member of the UCSF Human Genetics Institute, the California Institute for Quantitative Biology (QB3), ImmunoX and the UCSF Graduate Program of Bioinformatics. In addition, I am a an active member of the International MS Genetics Consortium (IMSGC) and principal investigator of the International multiple sclerosis microbiome study (iMSMS).

My laboratory focuses on the genomics, immunology and bioinformatics of complex diseases. I have extensive expertise in the analysis of genetic datasets in complex diseases, particularly in MS. My group has specialized in the post GWAS analysis of associated DNA variants. I am also the leader  the iMSMS, which includes some of the most renowned scientists working in the fields of MS and microbiome research worldwide. The iMSMS has collected stool samples from more than 1,000 patients and DNA sequencing analysis is currently underway.
