Alvaro Penteado Crósta is a Brazilian geologist, with international expertise in remote sensing, mineral exploration and planetary geology. He is an authority on the impact structures of Brazil and South America in general, and also known for the Crosta Technique, used in mineral exploration for detecting evidence of base and precious metals mineralization through multispectral and hyperspectral remote sensing images .[1][2][3][4]
Crósta got a Bachelor's degree in geology from the University of São Paulo in 1977, a Master's degree from Brazil's National Institute for Space Research (INPE) in 1982, and a Ph.D. degree from the Imperial College London in 1990. In 1995—1996 he was a visiting scholar at the Desert Research Institute of the University of Nevada at Reno.[1] In 2010 he acted as a visiting scientist at the Natural History Museum, Berlin, Germany, and at the University of Vienna, Austria. In 2018 he was a visiting scholar at the Universidad de los Andes, Bogotá, Colombia and in 2018/2019 a visiting scientist at the Jet Propulsion Laboratory, NASA/Caltech, Pasadena, CA, USA.
From 2005 to 2023 he was a Full Professor at the Geosciences Institute of the State University of Campinas (UNICAMP). He was the Institute's Director from 2005 to 2010[1] and UNICAMP´s Vice-Rector from 2013 to 2017. He retired in 2023 and remain attached to Unicamp in an honorary position. [5] He is a full Member of the Brazilian Academy of Sciences and a full Member of the Academy of Sciences of São Paulo State.
