Tomas Marangoni

Assistant Professor of Chemistry

Address: 5708 ESRB-Barrows, Room 261

Telephone: 207-581-2256






Professor Marangoni obtained his PhD from the University of Trieste in Italy. He then moved to the University of California Berkeley as a postdoctoral researcher where he worked on the synthesis of atomically precise Graphene Nanoribbons (GNRs). In 2016 he joined DuPont E&I developing high-performance electronic materials for commercial applications. In 2020 he received the Excellence in Science Award from DuPont E&I for his outstanding contribution in the field. He is now an assistant Professor at the Department of Chemistry and the FIRST institute at the University of Maine where his research activity is focused on developing new advanced organic materials for sensing and electronic applications.

The research activity of Professor Marangoni lays at the interface between chemistry, physics and nanotechnology with a key focus on the development of functional organic materials with new and exotic electronic and physico-chemical properties.
