Professor Fatayer's research interests are centered on understanding the fundamental properties of atomically precise systems adsorbed on surfaces (e.g. individual defects, single atoms, individual molecules and small molecular assemblies) from a physics and chemistry perspective. To achieve this, Fatayer's research group uses scanning probe microscopy under ultra-high vacuum and low temperature to observe individual molecules down to their component atoms. The group focuses on expanding existing approaches to investigate systems on top of insulating materials. Additionally, the group characterizes molecular ensembles of applied interest with atomic resolution and single-molecule specificity.​
