Geoffrey Roy
Post-doctoral researcher
Dr. at UCLouvain in 2015
Contact

Main project: Locoted
Funding: FEDER
Supervisor(s): Pascal Jacques

Geoffrey holds a Master in Mechatronic Engineering (2010) and a PhD in Engineering (2015) from the Université catholique de Louvain where he works as a senior researcher at the Institute of Mechanics, Materials and Civil Engineering (iMMC).
Within the Division of Materials and Process Engineering (IMAP), his research is focused on the development of new thermoelectric materials and systems for a range of applications going from industrial waste heat recovery to autonomous powering of smart sensors. In his research, he pays particular attention to the development of new solutions that present improved both technical and economical profiles in order to facilitate the emergence of these solutions out of the lab.
This research is followed by several companies such as: Drever International, AGC Glass Europe, Carmeuse or Engie.

IMMC main research direction(s):
Dynamical and electromechanical systems
Energy
Processing and characterisation of materials

Keywords:
energy harvesting
hybrid materials
metallic alloys
welding and joining

Research group(s): IMAP
