Casimiro Pio is a full professor of Applied Environmental Sciences, since 1993, at the University of Aveiro, Portugal. With a background in Chemical Engineering, obtained is PhD in 1981, in Environmental Sciences, at the University of Lancaster, UK. As a teacher at the University, he organized courses in Pollution and Environmental Sciences, participating in the establishment of the first course in Environmental Engineering in Portugal. In these and other courses, taught undergraduate master and PhD students in Analytical Methodologies, Chemical and Atmospheric Thermodynamics, Atmospheric Chemistry and Air Pollution and Quality. As a researcher, he has been working for approximately four decades in the field of environment, with special emphasis on atmospheric sciences and air pollution. He was one of the first researchers in Europe to develop methodologies and building equipment for the measurement of carbonaceous aerosols in the atmosphere, using thermo-optical methods. He was also one of the European researcher precursors in the application of source apportionment computing methodologies to apportion the formation processes and sources of atmospheric aerosols. He also developed research in subjects such as: physico-chemical properties of atmospheric aerosols; natural gaseous sulphur atmospheric compounds; volatile ammonium aerosols; emission of hydrocarbons by vegetation; sea breezes and coastal air quality; deposition fluxes of pollutants over vegetation; energy and CO2 fluxes at the boundary layer in rural and urban environments; industrial and indoor pollution; emission of pollutants by biomass burning; urban, rural and desert dust. In these areas, he has been a principal investigator, or coordinator, of several dozens national and international research projects. He supervised with success 20 PhD students and published approximately two hundred scientific papers, which had more than eleven thousand citations, resulting in a h index of 58. In scientific and academic administration, he was director of the Department of Environment during several years, member and adjunct president of the University Scientific Council. He founded and directed CESAM (Centre for Environmental and Marine Sciences), the larger research Unit in the University of Aveiro, with more than 200 PhD holding researchers, for 16 years, until 2017. Since December 2019 he is retired from teaching.
