Peter Nirmalraj is a molecular surface physicist who currently heads the biosensing and functional surfaces research group at Empa.
His core area of research interest and expertise is in applying cutting edge scanning probe microscopes to decipher the structure, dynamics and energetics of functional organics and biomolecules with high spatio-temporal clarity. Information obtained from such nanoscopic experiments are then focussed towards developing biosensing and logic devices.
After receiving his PhD for the work on applying conductive imaging atomic force microscopy to study electrical percolation in nanoscale networks in 2011 from Trinity College Dublin, Ireland he joined IBM Zurich Research Laboratory. Here at IBM, he developed an unorthodox route based on scanning tunnelling microscopy and spectroscopy operating in high-density liquids to electronically fingerprint nanomaterials. Later, in 2017 he joined the Adolphe Merkle Institute, Fribourg as group leader in Biophysics where he investigated the aggregation of amyloid beta peptides and developed novel cell imaging methodologies.
