Miłosz obtained his Bachelor’s degree in Biotechnology from Lodz University of Technology in Poland, where he developed a strong interest in genetic engineering. He subsequently completed a Master’s degree in Advanced Genetics at the Autonomous University of Barcelona (UAB), Spain. His master’s thesis focused on genetic interactions within the Fanconi anemia pathway, explored as potential therapeutic targets in translational and precision medicine. In 2024, he joined Prof. Manuel Kaulich’s laboratory, where his doctoral research centers on the interplay between transcriptional adaptation as a genetic buffering mechanism and nuclear speckles, as well as on the genetic dependencies in autophagy.

Privately, he's a committed activist and human rights educator, associated with Amnesty International and other local non-profit organisations.
