. He showed that "activator" proteins, which previously had been shown to play crucial roles in regulating gene expression in simple organisms, also exist in higher organisms. He and his colleagues further discovered several gene-regulatory proteins. Tjian is also notable in drug-target studies and their applications. Tjian developed some highly efficient and sensitive techniques to detect cellular quantities such as proteins. In 1989, Tjian, together with two colleagues David Goeddel (father of MLB players
