Miguel Araiz Vega studied industrial engineering at the Public University of Navarre (UPNA), Spain, and completed his Ph.D. at the same university in 2018. The topic of his thesis was the modelization and development of a thermoelectric generator to harvest waste heat in domestic and industrial processes. He is a member of the Thermal and Fluids Research Group and the Smart Cities Institute of the UPNA. He completed a short research stay at the Royal Melbourne Institute of Technology (RMIT) in Melbourne, Australia in 2018, and he has collaborated in many research projects related to thermoelectric generation and refrigeration, and simulation, design, and optimization of heat exchangers and thermal systems. He has published fourteen manuscripts in peer-reviewed international journals and one book chapter, and he has participated in more than twenty-five international and national conferences.
