Marco Reni

In a tragic accident in the mountains, Marco Reni died on Saturday 10th of June
2000, at the age of 37 years, on a climbing tour on a summit in the Carnian alps,
two hours distance north of Trieste. The mountains were the great passion and
vocation of his life, he knew very well most parts of the alps and had also
experience in Himalaya.

Marco was born on the 28th of September 1962 in Busto Arsizio, a town north of
Milano, as the second of six children. He studied physics at the University of
Milano taking his degree (Laurea) in 1986, with a thesis in mathematical physics.
In the same year he transferred to Trieste where he started a PhD-program at the
SISSA, a graduate school in science situated close to the ICTP (International
Center of Theoretical Physics, well-known also among mathematicians for its
conferences and its location in one of the most beautiful places of the Trieste
seaside). Here Marco started working in low-dimensional topology which should
remain his main working field from now on. After an interruption by his military
service in 1987/88, he got his PhD in 1991 at the SISSA. From 1991 to 1993 he was
in Paris at the University of Paris-Sud at Orsay (CNRS Topologie et Dynamique),
with a grant from the Italian government (CNR). In 1993 he obtained the permanent
position of Ricercatore at the University of Trieste. Winning in the last national
(centralized) Concorso of geometry in Italy in 1998, he became associate professor
at the University of Trieste on the 1st of November 1999. Among other places which
he visited for professional reasons for some extended period one may mention the
University of California at Santa Barbara and the University of Toulouse.

Premio Marco Reni

With the generous help from his friends, colleagues and in particular from his sister Anna Reni and her family,
a Premio Marco Reni, of 500 Euro, was created at the University of Trieste which is awarded once a year to
a student in mathematics at the University of Trieste who finished his studies with an excellent Laurea
(Laurea cinquennale up to 2005/2006, Laurea magistrale since 2007/2008). The price was awarded as follows:

2002/2003                Orsola Tommasi
2003/2004               Luis Alberto Molina Rojas
