He was the principal researcher of the Solar Submillimeter Telescope and Solar-T, and started the Atmospheric Science program at the Brazilian Antarctic Program. He founded research into radio astronomy, spatial geodesy, and solar physics in Brazil.^[1] He helped install the first radio telescope in Brazil in 1962,^[2] at the Professor Aristóteles Orsini Planetarium, but the antenna was subsequently destroyed by cows. He was funded by FAPESP is its first year of operation, to work on radio star scintillation.^[3] He also helped construct radio telescopes in Campos do Jordão and at Itapetinga Radio Observatory.^[3]

He was a professor at the Mackenzie Presbyterian University^[1] since 1998,^[4] where he was coordinator for the Center for Radio Astronomy and Astrophysics,^[3] and a senior researcher at the Centre for Semiconductor Components (Portuguese: Centro de Componentes Semicondutores)^[1] at UNICAMP, as well as an associate professor at the Polytechnic School of the University of São Paulo. He published over 200 papers, and supervised 17 Masters students, 7 PhD students, and 8 postdocs.^[3]
