Alex Adronov was born in Kaunas, Lithuania (part of former USSR), and immigrated to Canada with his family when he was seven years old. He received his BSc in honours biological chemistry from McMaster University in 1996. During his undergraduate studies, he participated in research projects within the groups of Françoise Winnik, Cornelia Bohne, and Michael Brook, during which time he developed his interest in polymers, chromophores, and fluorescence spectroscopy. He carried out graduate studies in the group of Jean M. J. Fréchet at University of California Berkeley. He received his PhD in 2001, and immediately took up an assistant professor position at McMaster University. There, he initiated a research program involving synthetic polymer chemistry, the functionalization of carbon nanotubes, and the development of novel polymer architectures. He was promoted to the rank of associate professor with tenure in 2007, and professor in 2013. He also served as associate chair of graduate studies in the Department of Chemistry and Chemical Biology from 2009–2015, and is currently the associate chair of research.
