Mission
Extreme environments are particularly sensitive to climate change and are transforming at accelerated rates. This can have important global repercussions. EERL aims to create integrated process understanding by investigating interactions between the atmosphere, cryosphere, biosphere, ocean, land and anthroposphere. The goal is to characterize climate-change relevant and vertically-resolved processes that are d

Florian Frédéric Vincent BreiderFlorian Breider obtained his PhD in the field of the stable isotope biogeochemistry from the University of Neuchatel in 2013. This was followed by seven months of postdoc at EPFL in the Atmospheric Particles Research Laboratory and two years as research associate at Tokyo Institute of Technology (Japan) where he conducted studies on nitrous oxide biogeochemistry in oceans. From 2015 to 2018, he was research scientist in the Laboratory for Water Quality and Treatment at EPFL where he conducted research on disinfection by-products and antibiotic resistant bacteria. Since May 2018, he is director of the Central Environmental Laboratory at the Institute of Environmental Engineering of EPFL.

Alexandros PapagiannisProf. Alex. Papayannis (Dipl. Ing., DEA, Ph.D.) is the Director of the Laboratory of Optoelectronics, Lasers and Applications (
http://www.physics.ntua.gr/~lola/pages/en.html
) and Professor of Atmospheric Physics, Laser Technology and Laser Remote Sensing at the National Technical University of Athens (NTUA). He received his DEA and Ph.D. Diplomas from the Université Paris 7, working at the Institut Pierre Simon Laplace (IPSL) du CNRS/Université Paris 6. He is affiliated to the Laboratory of Atmospheric Processes and their Impacts (LAPI) at EPFL.
He is a LiDAR expert (more than 35 years) in vertical profiling of atmospheric parameters, aerosols, bio-aerosols, clouds and gases (O3, H2O, glyoxal) in the troposphere, in combination with sun photometry, satellite data,
in situ
aerosol measurements and meteorological modelling. Being member of the 1st Tropospheric Ozone Network (TOR/TESLAS/EUREKA Projects) in Europe, he created, on 1996, the 1st European lidar Network (France, Switzerland, UK, Germany, Italy, Greece, Portugal). Soon after, he initiated the creation of several lidar groups in Greece, Brazil, Romania, China, etc., as well as of the RAYMETRICS lidar company (
www.raymetrics.com
), which is the first lidar company in the world with customers in throughout Europe, Americas, Asia and Africa. He is a founding member of the European lidar Network (EARLINET) (
www.earlinet.org
), which has been in operation since 2000. The NTUA lidar station serves as a calibration station of the CNES/NASA space lidar mission CALIPSO (
https://www-calipso.larc.nasa.gov/
) and the European Space Agency (ESA) space lidar mission AEOLUS (
https://www.esa.int/Applications/Observing_the_Earth/FutureEO/Aeolus/Introducing_Aeolus
).
His research focuses on the intercontinental transport of ozone, desert dust and biomass burning and continental aerosols and on their impact on clouds, climate, air quality and health. As his 1st Marie Curie ITN Grant (http://itars.uni-koeln.de/static/) combined the synergy of lidars, radars and micro-wave profiling systems to study of the aerosol-clouds interactions, his research is also focusing on the cloud formation processes based on such synergies. In recent years, his emphasis is also put on the typing and profiling of bio-aerosols using novel prototype lidar systems he designed and developed at NTUA.
He is member (2008-2015) and President (2015-2023) of the International Coordination Group for Laser Atmospheric Studies (ICLAS) (
http://iclas-ilrc.org/).
He has served as Co-chair and Member of the Scientific Committee of more than 26 International Conferences, related to lidar atmospheric/meteorological applications. He has participated in 67 research projects (EU, ESA, NASA, CNRS, INOE-Romania, IPEN-Brazil, and Greek national funds) and has published 132 papers in peer-reviewed journals, 6 Book chapters and 250 papers in peer-reviewed International Conferences Proceedings. He has received more than 8.100 citations (h-index 46) in Google Scholar. He has supervised more 15 Ph.D. students at NTUA and 60 M.Sc. Diploma Theses.

Short summary of my scientific carrer
After a graduation in chemical engineering from the University of Liège, I have obtained a Ph. D. from the University of Liège in the LASSC laboratory of Prof. Kalitventzeff (former president of the European working party on computer aided process engineering). This laboratory was one of the pioneering laboratory in the field of Computer Aided Process Engineering.
In the group of Professor Kalitventzeff, I have worked on the development and the applications of data reconciliation, process modelling and optimisation techniques in the chemical process industry, my experience ranges from nuclear power stations to chemical plants. In the LASSC, I have been responsible from the developments in the field of rational use of energy in the industry. My first research topic has been the methodological development of process integration techniques, combining the use of pinch based methods and of mathematical programming: e.g. for the design of multiperiod heat exchanger networks or Mixed integer non linear programming techniques for the optimal management of utility systems. Fronted with applications in the industry, my work then mainly concentrated on the optimal integration of utility systems considering not only the energy requirements but the cost of the energy requirements and the energy conversion systems. I developed methods for analysing and integrating the utility system, the steam networks, combustion (including waste fuel), gas turbines or other advanced energy conversion systems (cogeneration, refrigeration and heat). The techniques applied uses operation research tools like mixed integer linear programming and exergy analysis. In order to evaluate the results of the utility integration, a new graphical method for representing the integration of the utility systems has been developed. By the use of MILP techniques, the method developed for the utility integration has been extended to handled site scale problems, to incorporate environmental constraints and reduce the water usage. This method (the Effect Modelling and Optimisation method) has been successfully applied to the chemical plants industry, the pulp and paper industry and the power plant. Instead of focusing on academic problems, I mainly developed my research based on industrial applications that lead to valuable and applicable patented results. Recently the methods developed have been extended to realise the thermoeconomic optimisation of integrated systems like fuel cells. My present R&D work concerns the application of multi-objective optimisation strategies in the design of processes and integrated energy conversion systems.
Since 2001, Im working in the Industrial Energy Systems Laboratory (LENI) of Ecole Polytechnique fédérale de Lausanne (EPFL) where Im leading the R&D activities in the field of Computer Aided Analysis and Design of Industrial Energy Systems with a major focus on sustainable energy conversion system development using thermo-economic optimisation methodologies. A part from the application and the development of process integration techniques, that remains my major field of expertise, the applications concern :
Rational use of water and energy in Industrial processes and industrial production sites : projects with NESTLE, EDF, VEOLIA and Borregaard (pulp and paper).Energy conversion and process design : biofuels from waste biomass (with GASNAT, EGO and PSI), water dessalination and waste water treatment plant (VEOLIA), power plant design (ALSTOM), Energy conversion from geothermal sources (BFE). Integrated energy systems in urban areas : together with SCANE and SIG (GE) and IEA annexe 42 for micro-cogeneration systems.
I as well contributed to the definition of the 2000 Watt society and to studies concerning the emergence of green technologies on the market in the frame of the Alliance for Global Sustainability.
