Hans-Jörg Rheinberger

in 1982 with a dissertation concerned with protein biosynthesis and habilitated 1987 in molecular biology at the FU Berlin.

In his studies he describes "experimental systems" to be the driving forces within the development of the modern natural sciences.

[3] He developed his corpus of theoretical categories in dependence to the philosophy of Jacques Derrida and draws many inspirations form the works of Gaston Bachelard.

His main focus is aimed at the "structures of the experiment", which he deciphers by applying reconstructive analysis to the work in laboratories concerned with biological research.

According to Rheinberger promising "experimental systems" are distinguished by the amount of space the grant an "epistemic thing" to unfold itself.

The boundary between "epistemic thing" and "technical object" is not static and identifying something as either or not permanent.
