Assistant Professor in University of Lisbon, Instituto Superior Técnico, and an Integrated Member of CERENA (Centro de Recursos Naturais e Ambiente). Adilson Alves de Freitas graduated in Chemistry in 1998 at Institute of Chemistry, University of São Paulo (USP), Brazil, completed his MSc degree in 2001 (thermodynamics of solubilization of organic solutes into surfactant micelles) and his PhD degree in Physical Chemistry in 2005 (thermodynamics, kinetics and photophysics of natural pigments in micellar environment), both at USP. Works in the Chemical Sciences, with emphasis on Physical Chemistry and Physical Organic Chemistry. He mantains collaborations with research groups in Portugal, Spain, Belgium, Austria, UK, USA, Canada, Brazil, China, Japan and Australia. Adilson has large experience in Time-Correlated Single Photon Counting (picosecond resolution) and Ultrafast Time-Resolved Femtosecond Fluorescence Upconversion systems, and has developed software tools and analytical models to interpret complex fluorescence transients. He has more than 30 years of experience in DFT, ab initio and semi-empirical computational methods (Gaussian, ORCA, DALTON, AMSOL and Spartan packages), contributing on reparameterization of the PCM solvation model, theoretical pKa calculations, redox potentials, electronic transitions, and reactivity analysis. Since 2014, he has been actively engaged in MD simulations of many chemical and thermophysical aspects of pure Ionic Liquids, electrolytes, IL in mixtures, IL in solutions, liquid-liquid and solid-liquid interfaces, and has developed software for MD data analysis. His research interests include the kinetics and thermodynamics of ultrafast processes in organized systems; chemistry and photophysics of flavylium salts, anthocyanins and pyranoanthocyanins; structure and dynamics of ionic liquids and other concentrated electrolytes; cement chemistry; linear free energy relationships (LFERs).
