The Rocha Medal

 

The Rocha Medal

The ISRM Board decided at its Tokyo meeting in September 1981, to institute an annual prize with a view to honour the memory of Past-President Prof. Manuel Rocha. Profiting from the basis established by Prof. Müller, Prof. Rocha organized the first ISRM Congress and he was the leader that was responsible for transforming the international collaboration carried out in an amateurish way into a real international scientific association, having for the purpose settled the fundamental lines that have guided and supported the ISRM activity along the years.

The Rocha Medal is intended to stimulate young researchers in the field of rock mechanics. The prize, a bronze medal and a cash prize, have been annually awarded since 1982 for an outstanding doctoral thesis selected by a Committee appointed for the purpose.

Starting with the 2010 award, one or two runner up certificates (Proxime Accessit certificates) may also be awarded.
