Philippe Tassin

Professor at Condensed Matter and Materials Theory

Philippe Tassin teaches physics and optics and leads a research group on electromagnetic structured media and computational electrodynamics.



He was born in Belgium and lived in several countries at both sides of the Atlantic Ocean. At the age of 17, he won a bronze medal at the International Chemistry Olympiad. Graduating in electrical engineering and applied physics, he obtained a M.Sc. degree and a Ph.D. degree from the Free University of Brussels, both summa cum laude. After his doctoral studies, he had postdoctoral appointments at Iowa State University and Ames Laboratory (a national lab of the U.S. Department of Energy). Dr. Tassin is now professor of physics at Chalmers University, where he teaches physics, optics, quantum mechanics, and computer science courses. His teaching was recognized with the Golden Chalk by the students and with Chalmers' Pedagogical Prize.



Philippe Tassin's research interests encompass the physics of electromagnetic structured materials and systems, including metamaterials, plasmonics, and nanophotonics. His research has led to well-cited publications in scientific journals, including papers in Science, Nature Photonics, and Physical Review Letters, and he is frequently asked to deliver invited talks at international conferences. His research has been recognized by awards and fellowships from KAW, Vetenskapsrådet, IEEE, SPIE, and the Flemish Research Foundation. He received the BAEF Alumni Award from the Belgian-American Educational Foundation and the Frans Van Cauwelaert Award, one of the major awards of the Royal Flemish Academy of Belgium for Science and the Arts.



Dr. Tassin is an editor of the journal "Photonics and Nanostructures," a leading journal in the nanophotonics field, and he is a frequent reviewer for most journals in his field. He is a member of the Young Academy of Sweden and a senior member of SPIE and IEEE. He is a founding member and vice-chairman of the IEEE Photonics Sweden Chapter. He is also active in the promotion of science and technology to the public and to students.
