Alexandre Payez

Alexandre Payez is a Remote Sensing Researcher at the Royal Netherlands Meteorological Institute (KNMI) in De Bilt, Netherlands, working within the R&D Satellite Observations department. His career includes significant positions as a Remote Sensing Researcher at the Royal Meteorological Institute of Belgium (2019-2021) and as an ESA Internal Research Fellow at the European Space Agency's Flight Dynamics section in Darmstadt, Germany (2015-2017). Earlier, he served as a volunteer teaching assistant for Lagrangian Mechanics and Special Relativity at the University of Liège's Department of Astrophysics, Geophysics and Oceanography (2009-2012).

Payez's research spans two interconnected domains. His early work (2008-2016) focused on theoretical particle physics, particularly using astronomical observations to constrain axion-like particles through quasar polarization studies and supernova data. His later research (2017-2025) shifted toward applied Earth observation, developing methods to analyze extreme wind speeds, hurricane trends, cloud motions, and Earth's radiation budget using satellite data. This evolution demonstrates his unique ability to apply fundamental physics principles to practical climate monitoring problems.

His publication record reveals a sophisticated analytical approach across disciplines. The recent work on extreme value methods for hurricane wind trends and phantom motion in ocean observations showcases innovative statistical techniques applied to climate data. Meanwhile, his earlier research on axion-like particles established important constraints using quasar polarization measurements, contributing to the understanding of potential dark matter candidates. Both research streams demonstrate exceptional mathematical rigor and cross-disciplinary thinking.

Payez has published 26 scientific papers accumulating 1,973 reads and 939 citations. His most significant collaborations include work with Jean-René Cudell from the University of Liège, Andreas Ringwald from Deutsches Elektronen-Synchrotron, Ad Stoffelen from KNMI, and Dominique Sluse from the University of Liège. His research continues to evolve with current work focused on climate change detection through analysis of extreme weather events using satellite observations.
