Summary
👤
Senior🎓
Top SchoolWojciech Krzemien is an assistant professor at the National Centre for Nuclear Research in Warsaw who blends experimental physics with telecoms engineering and over a decade of scientific software development. He leads AI-enhanced imaging projects such as IMPET and previously headed the Total Body Software Group for cost-effective polymer PET tomography, marrying Monte Carlo simulation, image reconstruction and machine learning for noise reduction. A long-standing member of LHCb and J-PET collaborations, he has contributed to fundamental physics analyses—from quantum correlation studies to mirror matter searches—while also integrating distributed computing solutions like RabbitMQ into DIRAC Grid workflows. His work bridges high-performance computing, scientific instrumentation and applied ML, and he has coordinated national supercomputing resources for EuroHPC PL. Multilingual and academically seasoned with MSc degrees in telecommunications and physics plus a PhD from Jagiellonian University, he thrives on probing quantum rules and translating that curiosity into practical imaging and software solutions.

Contributions summary:Wojciech implemented a messaging queue interface using RabbitMQ. They added stubs for classes used for RabbitMQ consumer integrations, including a RabbitMQ.py interface class for message management. They also developed a script to launch DIRAC consumers, indicating a focus on distributed computing and workflow management within the DIRAC Grid environment. Furthermore, they added code to manage the RabbitMQ database and its user permissions.
