My research focuses on understanding what controls electrochemical energy conversion and storage from the atomic scale. This is the key question in all electrochemical technologies ranging from hydrogen production through water splitting to green electricity generation using fuel cells, CO2-to-chemicals concepts, sustainable ammonia production for fertilizers and fuels, and various other applications.
To answer this question, we develop and apply theoretical and computational method to address electrochemical processes at different time- and length-scales. We are developing combining constant potential density functional theory, rate theory, model Hamiltonian approaches, and multiscale methods: combining these methods allows us to study electrochemical systems under realistic experimental conditions from the atomic level to reactor scales. These tools are then applied to understand and find better materials for electrocatalytic applications in hydrogen production and CO2 conversion, the oxygen reduction reaction in fuel cells, and glycerol oxidation to valueable chemicals. Besides applications in green processes, we also study the basics of electrochemical systems such as electrode potential, solvent and electrolyte effects, (proton-coupled) electron transfer kinetics and thermodynamics, and reaction mechanims at electrochemical interfaces.
I am currently an Academy of Finland Research Fellow at the Department of Chemistry and the Nanoscience Center. I also hold a docenture (Adjunt professorship) in physical electrochemistry.
