Welcome to the Ryan Research Group

The Ryan  Research Group at the Bernal Institute is led by Professor Kevin M. Ryan who holds a Personal Chair in Chemical Nanotechnology at the Department of Chemical Sciences  at the University of Limerick. He is coordinator of the H2020 EU projects Si-Drive and NEILLSBAT in the area of  Li-ion and Lithium-Sulfur batteries respectively, Co-Principal Investigator on SFI Centres MaREI and AMBER and funded Investigator on SSPC. He is holder of SFI IVP and IRC Laureate awards.  Previous affiliations included Marie Curie Fellowship positions at the University of California, Berkeley, USA and Merck Chemicals Southampton, UK following  BSc and PhD degrees at University College Cork. The group research Interests are in  Nanocrystals and Nanowires with emphasis on Synthesis, Assembly and Device Applications in ICT, Energy Storage (Batteries) and Energy Conversion Applications. The group also studies nucleation and growth in both hard (metal, semiconductor) and soft (pharmaceutical) nanocrystal materials with emphasis on size, shape and crystal phase control.
