My Research: Pharmacogenomics

Discovery of regulatory genetic variants in genomics and pharmacogenomics

Sadee has led a systematic effort to discover regulatory variants in critical genes affecting disease and treatment outcomes, using genomics databases and experimental procedures. He has employed early on the use of allelic RNA expression imbalance as a powerful tool to detect cis-acting regulatory variants affecting transcription, RNA processing and functions, and translation.
