Schrader conducted foundational work in the early days of computer science and was appointed one of the Institute's Professors of Informatics in 1984.
He wrote a number of books on both mathematics and philosophy, including "Equality, the Similarity of the Order" (1970), "Systems and Models" (1980), "The Nature of Biological Knowledge" (1991), "Fundamentals of Ethics" (1993), and "The Values That We Choose" (1999).

In 1970, Schrader was baptized in the Roman Catholic Church, an uncommon occurrence in the secular culture of the Soviet Union.
In 1991, Schrader became Professor of the College of Catholic Theology of Saint Thomas Aquinas, and in 1996 Professor of the Biblical Theological Institute of Saint Andrew in the city of Moscow, where he taught courses on "Ethics," "Social Doctrine of the Church", and "Logic and Epistemology", among others.
Gelfand found one small error, but the solution proposed by Schrader was interesting, and later became the basis of his doctoral dissertation.
