Professional Objectives
I like being involved with the development of new and promising technologies.
Most interesting to me are DSP applications and novel
combinations of mechanical, electrical and computational components. My
goal is to work in a field where my technical, analytical, and writing skills
are complemented by my creative experiences as an engineer and an artist.
