Hakan Göçerler studied mechanical engineering at Dokuz Eylül University in Izmir, Turkey. His master's thesis entitled "Submicrometric Evaluation of Workpiece Surfaces in the Precision Manufacturing and Nanotechnology" was written as part of a cooperative project and accepted at the Vienna University of Technology. Following his Master's thesis, he worked at the Helmholtz-Zentrum Geesthacht on a project on the joining and evaluation of hydrogen tanks. He was then accepted into the European project WEMESURF. He spent a year at the CIMaINa University of Milan to determine the mechanical properties of human skin using atomic force microscopy. The following year, he was employed by the Philips Applied Technologies Center Eindhoven as part of the WEMESURF project, where he worked on the development of a tribosystem to analyze the interactions between contact lenses and corneal cells.

Pierluigi Bilotto did his undergraduate studies in physics at University of Calabria (Italy). The bachelor thesis was on bouncing droplets as fluid dynamics macroscopic objects able to mimic properties of the quantum world. The master thesis was on the nanomechanics of recombinant mussel foot proteins to reveal the adhesion mechanisms that could grant accessibility to a glue working underwater.  P. Bilotto received his PhD at TU Wien in 2021 under the supervision of prof. M. Valtiner. The scope of the PhD thesis was to reveal the adhesive behaviour of bio interfaces in extreme conditions such as high electrolyte concentration, and competition or cooperation of elements decorating the bio interface.

Right after the PhD, P.Bilotto started as Senior Researcher in CEST (centre for electrochemistry and surface technologies) in Wiener Neustadt (2021). There, he started to work on two-dimensional materials (2DM) such as graphene oxide and MXenes. On the latter, he was focusing on open questions about their production, electronic applications, or integration in biointerfaces. He managed and co-supervised projects in the field of nanomechanics, for instance for the removal of nanoparticles or the adhesion of human collagen involving industrial partners and international collaborators.

In the group P. Bilotto will focus on understanding tribology at the nanoscale involving 2DMs and biointerfaces.
