Other Awards

Jan 2013
G. Cilento Award 2012
Professor Giuseppe Cilento was one of the foremost scientists in South America and a pioneer in photobiology. His research at the Institute of Chemistry of the University of Sao Paulo demonstrated conclusively that excited triplet states can be generated enzymatically and he had the foresight to perceive that these could be reactive intermediates of importance in biology. Cilento excelled as a mentor and many of his former students and post-doctoral associates hold academic positions in Brazil and other countries. The breadth of their research interests is a direct reflection of Cilento's interdisciplinary approach to science. The G. Cilento Award was created as a result of the first I-APS South American Meeting in Iguazu Falls in 1996 with the objective of facilitating the participation of young (up to age 35) scientists and students working in Latin America in the I-APS Annual Conferences.
