Teaching assistant coaching students in several lectures

Advanced Energetics

where the student's mission is to optimise thermoeconomically industrial processes
Methods for the rational use and conversion of energy in industrial processes : how to analyse the energy usage, calculate the heat recovery by pinch analysis, define heat exchanger network, integrate heat pumps and cogeneration units and realise exergy analysis of energy conversion systems.

Modelling and Optimization of Energy systems

where students are familiarized with the modelling of energy systems through the example of the EPFL heating system.
The goal of the lecture is to present and apply techniques for the modelling and the thermo-economic optimisation of industrial process and energy systems. The lecture covers the problem statement, the solving methods for the simulation and the single and multi-objective optimisation problems.Life cycle assessment in energy systemsThis course introduces students to Life Cycle Assessment (LCA), a comprehensive methodology for evaluating energy conversion technologies and other systems across their entire value chain, considering a spectrum of environmental issues beyond just climate change. Students will gain foundational knowledge of LCA's conceptual framework and basic principles in line with ISO 14040/44 standards.

Life cycle assessment in energy

where students are introduce to the Life Cycle Assessment (LCA) as a holistic approach to evaluate, among others, energy conversion technologies throughout their entire value chain, and across multiple environmental problems beyond climate change.
The course objectives include understanding how to define the goal and scope of an LCA study, grasping the computational structure of LCA, and learning to model technological systems, emissions, and resource consumption. Students will also develop skills in interpreting LCA results, appreciating the influence of modeling choices, and identifying the method's current limitations. A significant focus will be on identifying major environmental issues associated with both current and new technologies, as well as analyzing the environmental benefits of integrating energy systems throughout the value chain. This course is designed for students interested in environmental sustainability, energy systems, and the broader impacts of technology on the planet.
