His research interest are primarily in the area of organic electronics.

He has contributed in the understanding of structural electronics effects of organic conjugated materials at molecular, supramolecular, and macromolecular levels via the study of small molecules, supramolecular (co-)assemblies, polymers, covalent organic frameworks, and on-surface assemblies/polymers.

in top-tier chemistry and materials journals such as Nature Materials[6] Nature Chemistry,[7] Journal of the American Chemical Society,[8] Angewandte Chemie International Edition, [9][10] etc.

Furthermore, he has published book chapters, as well as having over 100 invited seminars and invited conference presentations.
