Research
Outline
My
current research focuses on surrogatebased 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, tuning and related methodologies in RF/microwave
design,
nondestructive testing and aeroacoustics. My other projects involve
analog signal processing, especially continuoustime active filters and
highlylinear transconductance amplifiers as well as evolutionary
computation in application to VLSI design, including converterfree
lowpower design and circuit partitioning.
