L. M. Goncalves graduated in 1993 and received his MSc degree in 1999, both in Industrial Electronics Engineering from the University of Minho, Portugal. His PhD thesis was on thermoelectric microsystems for on-chip cooling and energy harvesting, Cardiff/Minho (2007). From 1993 to 2002, he researched embedded systems and electronics, and since 2002, he has been lecturing at the Electronics Department, University of Minho. He has experience in microelectronics, micro-fabrication, thin-film deposition, characterization, and patterning, particularly in thermoelectric materials and micro-devices for energy harvesting and sensors. His current interests focus on microelectronic sensors for oceanic applications.
