Dr. Harley also builds infrastructure with which to do high throughput genotyping, expression analysis, and epigenetics, which he makes available to his colleagues from around the world. In recent experiments, Dr. Harley organized the logistics of managing >18,000 subjects at >30,000 genetic markers, 3200 subjects at 1.2 million markers, and 10,000 subjects at 196,000 markers. Dr. Harley is committed to all of the steps between association detection through replication and toward identifying the possible functional genetic variants and to pursuing their biology.
