My research

My interests are focused on experimental testing of discrete symmetries in neutral mesons systems (KLOE-2 and LHCb projects), and formerly on the search for a new kind of matter, the so-called mesic-nuclei (WASA project). Those topics are related to fundamental questions in modern physics e.g. the asymmetry of matter over antimatter, the basics of quantum mechanics (quantum oscillations, entanglement and decoherence phenomena), the validity of the fundamental CPT and Lorentz symmetries and the existence of a new kind of matter.

In parallel to the research in fundamental science, I am a senior researcher in the J-PET project , which aims at the construction of a novel cost-effective, total body PET tomography scanner. My work consists of the coordination of software development tools including image reconstruction algorithms, Monte Carlo simulations and data analysis framework. I am also the founder of a group focused on medical data reconstruction and processing using GRID and Cloud solutions.

Finally, in the frame of the LHCb project, I participate in the development and implementation of the scalable Pilot Logger system based on the Message Queue architecture (RabbitMQ, ActiveMQ) as a part of the DIRAC middleware. I also coordinate the software activities of the NCBJ group dedicated to the upgrade of the reconstruction algorithms and to the application of Machine Learning methods for the Electromagnetic Calorimeter.

As a by-product, my center of interests includes programming, security, image reconstruction, statistics, machine learning methods and more.
