About me

My main topics of interest:

-            Development of analytical and resistive-capacitive models of close-loop ground heat exchangers (geostructructures…), thermal response testing with uncertainty quantification and propapgation,

-            Design and design of multi-component thermal energy systems, coupling ground heat exchangers, solar thermal, heat pumps, sorption chiller, etc.,

-            Multi-objective optimization between competing objectives (cost, CO2-eq content, etc.)
