Piotr Sobieski
Professeur ordinaire émérite
SOBIESKI Piotr was born in Brussels, Belgium on December 7, 1948. He received the degrees in Electrical Engineering in 1971, Ph.D in 1977 and Habilitation in 1987 from Université Catholique de Louvain (UCL), Belgium. He has been Full Professor (professeur ordinaire) at UCL with classes in electromagnetism, wave propagation, telecommunications and microwave remote sensing. He has been Head of the Department of Electrical Engineering for the period 1995-2001. He was chairman of all the Examination Jurys for the Louvain School of Engineering for the period 2005-2014.
Between 1971 and 1980, he is involved in propagation of microwaves through the atmosphere, particularly attenuation and depolarisation of microwaves by hydrometeors, ground based radiometry, and in the european communication satellite OTS campaign at the Université Catholique de Louvain, Belgium.
In 1980-1981, he worked at the technical center (ESTEC ) of the European Space Agency, The Netherlands, where his activities concerned inverse scattering problems in electromagnetics especially in the frame of microwave remote sensing. The problem of the retrieval of geophysical parameters from multiple satellite borne microwave sensors has been addressed.
Between 1981 and 1990, he was involved in activities in microwave remote sensing, the scattering of microwaves by the rough sea surface with applications to satellite borne observations and maritime mobile propagation and communications. More specifically he worked on a unified approach of passive and active measurements, the development and validation of theoretical and numerical electromagnetic scattering models for the sea and the atmosphere, radiometric and radar measurements simulation, synergic inversion of field data.
In 1990-1991 he was visiting scientist at NASA Goddard Space Flight Center and works on problems related with microwave remote sensing of rain above the ocean from space.
Since 1991 he worked at UCL on various remote sensing problems about precipitation and the ocean on one hand, vegetation and soil on the other hand, in cooperation with NASA (USA), ESA (NL), CETP (F), IMST(F), Ifremer (F) and other european laboratories with financial support of ESA and the Belgian OSTC . He is involved in several ESA pilot projects in microwave remote sensing and use of data collected by ERS-1/2, TOPEX/POSEIDON , SSM/I and TRMM satellites. He is author and co-author of several papers in this field.
Since 1992 he was also involved in various pedagogical projects at the Louvain School of Engineering , UCL. He significantly contributed to the development of active pedagogy and the set up of a new educational program based on Problem and Project Based Learning started at UCL in 1999, coordinated Projects at the bachelor level for the period 2000-2014, organized PBL courses in Physics and Electromagnetism for the same period. Since that time he coordinates Group Dynamics Activities to train young tutors for Tutored Active Learning in Small Groups for the Louvain Schools of Engineering and Bio-engineering. In 2010 he co-founded a pedagogical spinoff of the faculty and UCL named FA2L.
P. Sobieski has been member of IEEE, URSI , the American Geophysical Union and the Belgian society of telecommunications engineers SITEL. He also acted as Associate Editor for Radio Science and Editor for the URSI Radio Science Bulletin for the period 1997-2001. He was Vice-Chairman of URSI Commission F devoted to "Wave propagation and Remote Sensing" for the period 2002-2005 and is Chairman for the period 2005-2008.
Since 2005, he significantly contributed at UCL to the implementation of new Bachelor and Master Degrees in the framework of the European Bologna Process towards the European Higher Education Area .
In the period 2008-2015 he chaired the "Groupe Programe d'Etudes" of UCL to manage and process any study program modifications at UCL for all faculties.
In october 2014 he became Professor Emeritus, and is currently Visiting Professor at UCL.
