About me

I graduated in physics from the Maria Curie Skłodowska University in 2000, where I also obtained a doctoral degree in 2005 and habilitation in 2014. In the years 2000-2005 I was a member of the Tomasz Goworek’s group, who proposed an extended model of positronium annihilation. The model allowed to extend the applicability of positron annihilation lifetime spectroscopy to characterization of mesoporous materials. I took a significant part in the development of this model, its implementation in a computer code, experimental verification and various studies related to porous materials. I continued this work independently proposing another extension, which enabled using the model for measurements performed in air.

Among my studies, I find particularly interesting in-situ studies of the processes taking place in the mesopores observed with a microscopic positron probe: thermal decomposition, adsorption, phase behavior of confined substances, experimental measurement of negative pressure under concave meniscus etc. In parallel, I deal with the fundamental issues of positron and positronium in organic materials, as well as applied research on the strengthening of the surface layer of construction materials, food processing,  controlled drug delivery, positron emission tomography and material science. I specialize in positron annihilation lifetime spectroscopy but I am also proficient in various material characterization techniques.

I have authored or co-authored over 90 peer-reviewed articles and reviewed over 60 articles. I am a member of Polish Physical Society and international Society For Positron Annihilation and Nuclear Probes. I collaborate with many research centers: Idaho National Laboratory, Helmholtz Center Dresden-Rossendorf, Slovak Academy of Sciences etc. I work as an associate professor in Department of Material Physics at the Maria Curie Skłodowska University. My teaching activities include nuclear physics and energy, automatic measurement and control of measuring apparatus, project management, analysis and presentation of scientific results etc.
