Marcin Gruszczyński was born in August 1999. He began his studies at Adam Mickiewicz University in 2018. A year later he joined Professor Hreczycho's research group and started working with silsesquioxanes, mainly synthesis and further functionalization. In 2020 he started working on pincer complexes, the synthesis of ligands, and new catalysts. During this research, he also contributed to other scientific publications associated with the synthesis of thiosilanes and selenosilanes. His research is focused on finding new catalytic complexes which could provide high sustainability together with selectivity and activity. In his spare time, he enjoys going out with friends, playing computer games, or watching some good thriller movies.
