What is your career trajectory to date? 

During my Master studies I got interested in applying machine learning (ML) techniques for particle physics experiment data analysis. I developed a method for analyzing the data from the Electromagnetic calorimeter of the PADME Experiment, aimed at searching for a Dark Photon and successfully implemented it in the experiment reconstruction. I now look forward to developing more advanced ML-based algorithms for complete reconstruction of detector data during my PhD. This will hopefully help us better understand the phenomena in the experiments, make our analysis much more precise with the aim to catch all significant events.

What are the most exciting open questions in your research area?

Physics beyond the Standard Model provides us with many open questions and many different paths one can take while searching for an explanation for what we observe. The many unknowns in the field lead to a vast variety of hypotheses and this uncertainty is a huge challenge which baffles my mind every day. The existence of Dark Matter was first proposed as an explanation for astronomical observations, but its constituents are a subject of particle physics research. This bridge between the science that studies the largest known objects and the one that studies the smallest particles in the universe shows how important it is to understand the world around us – but also how much more work awaits us.

What role do you think a network like COSMIC WISPers can play in developing WISP searches in Europe ?

Many different experiments are aimed at WISP searches and it’s important for them to exchange methods and ideas – as much as the different experiments have adopted different techniques, the experience exchange is vital for their existence. All of this needs to be backed up by serious theoretical knowledge and, last but not least, inter-disciplinary approach to the problem. All of this can be made possible exactly by networks like COSMIC WISPers, so that as many experts as possible can come together in an effort to solve the universe’s greatest mysteries.
