Prof. Radosław Zaleski is a worldwide known specialist in positron annihilation. He graduated in physics from the Maria Curie Skłodowska University in 2000 where he obtained a doctoral degree in 2005 and presented the habilitation dissertation in 2014. In the years 2000-2005 he was a member of the Professor Tomasz Goworek’s team working on an extended model of positronium annihilation.
The model allowed to extend the applicability of positron annihilation lifetime spectroscopy for characterization of mesoporous materials. Prof. Radosław Zaleski had a significant contribution to development of this model, its implementation in a computer code, experimental verification and various studies related to porous materials. He continued this study independently proposing another extension, which enabled using the model for measurements performed in air. Of his studies those in-situ of the processes taking place in the mesopores observed with a microscopic positron probe were particularly interesting: thermal decomposition, adsorption, phase behavior of confined substances, experimental measurements of negative pressure under concave meniscus, etc.
At the same time he focuses on the fundamental issues of positron and positronium and organic materials, as well as applied research on the strengthening of the surface layer of construction materials, food processing, drug delivery, positron emission tomography and material science. He specializes in positron annihilation lifetime spectroscopy being also proficient in various material characterization techniques.
Prof. Radosław Zaleski has authored or co-authored over 90 peer-reviewed papers in reputable journals and reviewed over 60 articles. He is a member of the Polish Physical Society and the International Society For Positron Annihilation and Nuclear Probes. He collaborates with many research centers, e.g. Idaho National Laboratory, Helmholtz Center Dresden-Rossendorf, Slovak Academy of Sciences, etc. He works as an associate professor at the Maria Curie Skłodowska University. His teaching activities include nuclear physics and energy, automatic measurements and control of measuring apparatus, project management, analysis and presentation of scientific results, etc.
