Juan Pablo Trelles, Ph.D. joined the Dept. of Mechanical Engineering at UMass Lowell as an assistant professor in the fall of 2012. At UMass Lowell, he conducts computational and experimental research focused on the direct use of solar and electrical energy in industrial processes, from power generation and waste-to-energy, to chemical synthesis and advanced manufacturing, as well as on the fundamental understanding of energy transport under non-equilibrium conditions. Before joining the faculty at UMass Lowell, Trelles was a senior software engineer in the Dept. of Process Technology Modeling group at Intel Corporation. His doctoral and post-doctoral research, conducted at the High Temperature and Plasma Laboratory at the University of Minnesota, involved the fundamental and applied study of flow instabilities and non-equilibrium processes in thermal plasma devices. His doctoral research led to novel Variational Multiscale Finite Element Methods for multi-physics and multi-scale transport problems. Trelles’ previous research experience includes the design of solar energy utilization devices and systems for standalone sustainable operation and for electricity generation from biogas.
