Anders Hellman

Docent at Chalmers, Physics, Chemical Physics

I am a theoretical physicist that works within the field of surface science, heterogeneous catalysis and materials for energy applications. Research interests include charge-transfer processes, hot-electron chemistry, surface reactions, phase transformations and time evolution of catalytic reactions.Anders Hellman received his PhD in theoretical physics in 2003 from University of Gothenburg, Sweden. He has done postdoctorial studies at Haldor Topsoe A/S, Denmark’s Technical University, and at Chalmers University of Technology, Sweden. He now works as an Associate professor at the department of Physics, and is also associated with the Competence Centre for Catalysis, Chalmers, Sweden. He is the leader of the Materials for energy application profile shared between the Energy Area of Advance (AoA) and Material AoA, Chalmers.He has worked on various topics related to surface science, heterogeneous catalysis and materials for energy harvesting, such as, charge transfer and non-adiabaticity in surface reaction, ammonia synthesis, CO and methane oxidation, thin oxides supported on metals, and photoelectrochemical studies of water oxidation. Hellman is the author and co-author of more then 50 papers in international journals, 4 book chapters, and has given many invited and keynote lectures at international conferences on the topics above.
