Research in our laboratory spans the traditional areas of organic, inorganic and physical chemistry as well as interdisciplinary areas of modern chemical research, focusing in particular on the chemistry of elements (elements chemistry). We aim to better understand the reactions, properties, and structures of chemical substances not only by means of experimental approaches based on synthetic organic chemistry and spectroscopy, but also from a theoretical viewpoint based on computational chemistry. Our research interests include development of innovative chemical reactions, and design and synthesis of new functional molecules.
