Ruslan I. Dmitriev graduated from Lomonosov Moscow State Academy of Fine Chemical Technology (MSc) and Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry (PhD, 2008), where he studied membrane ion-transporting proteins and protein interactions. He trained as postdoc at University College Cork, focusing on cell metabolism, hypoxia research and development and biological applications of cell-penetrating phosphorescent probes for molecular oxygen. Since 2014, he leads Metabolic Imaging group at University College Cork, where he designs novel biocompatible FLIM and PLIM biosensors for 3D tissue models for regenerative medicine and cancer biology.
