Yaroslav Grosu leads the Interfacial Phenomena, Colloids and Porous Media group at CIC energiGUNE, a position he has held since 2021. He is also Honorary Professor of Surface Science and Energy Materials Engineering at the University of Birmingham, UK.

He received his doctorate in 2015 through a cotutelle programme between Université Blaise Pascal, France, and the National Technical University of Ukraine “Kyiv Polytechnic Institute”. His doctoral research investigated solid–liquid interfaces under nanoconfinement for energy storage. He joined CIC energiGUNE in 2015 and subsequently established an independent research programme connecting confined-fluid thermodynamics, porous materials and interfacial energy conversion.

His research investigates how nanopore size, chemistry and connectivity alter fluid behaviour for the benefit of novel energy applications. He has developed experimental platforms combining pressure–volume–temperature measurements with calorimetry or electrical measurements, complemented by neutron and synchrotron experiments. His contributions include applying liquid-water intrusion to investigate confined-water criticality, revealing unusual mechanical and thermal responses of water–MOF systems, and developing electro-intrusion and molecular-spring concepts for energy storage and conversion.

His recognition includes a Ramón y Cajal fellowship, awarded in 2022 with the second-ranked application in Energy and Transport, and he serves on the editorial boards of Energy Storage and Saving (Elsevier) and Scientific Reports (Springer Nature).
