Rannsóknir

My current research focuses on surrogate-based modeling and optimization including space mapping technology for engineering design. There are ongoing projects that involve theory of space mapping, development of new algorithms and modeling techniques as well as applications of space mapping and related methodologies in RF/microwave design, nondestructive testing and aeroacoustics. My other projects involve analog signal processing, especially continuous-time active filters and highly-linear transconductance amplifiers as well as evolutionary computation in application to VLSI design, including converter-free low-power design and circuit partitioning.
