The researcher provided seminal biological insights into schizophrenia by analyzing 108 associated genetic loci, establishing a foundational framework for understanding the disorder's genetic architecture.
The researcher developed LD Score regression to distinguish confounding from polygenicity in genome-wide association studies, a method that has become a standard tool for interpreting GWAS results.
