He participated in the founding of the Center for the Study of Biological Complexity at Virginia Commonwealth University.
[5] Kier built one of the first models in which molecular orbital theory was applied successfully to drug design and development.
Later, he and his colleague, Lowell Hall, developed what is now called the "Kier-Hall Index" to describe molecular connectivity.
