Research Interests
My research interests include the development and application of massively parallel computation methodology known as neural networks or connectionist networks. Methodology development focuses on the idea of matching the structure/architecture of a network to structural relations in data of problem context. This requires developing a common mechanism for describing structure in data and structure of a network so a matching process can be possible. One approach is based on a knowledge representation formalism known as conceptual structures, and another is based on a structure representation formalism called general systems methodology (GSM) notation. Applications being pursued include pattern recognition and implementation of selected database/expert system operations. In the planning stage are control applications. Future work includes collaboration with other faculty in developing analog/digital VLSI implementations of neural networks.

Jeff Hoffman & Don Tornquist have been chosen for the 2009-2010 ECE Undergraduate Honors Program. The program enables undergraduates to go beyond their normal studies to work with faculty in the area of their choice: research, entrepreneurship or innovation.

Robert Daasch

Dr. Robert Daasch has won the Semiconductor Research Corporation 2009 Technical Excellence Award. It is the second highest research award in the SRC. The Technical Excellence Award was established as an incentive and recognition program for research of exceptional value to GRC members. Authorized by the Board of Directors in December 1991, the award is intended to complement the Inventor Recognition Award. The Technical Excellence Award is shared among key contributors for innovative technology that significantly enhances the productivity/
competitiveness of the semiconductor industry. To date 25 research efforts have received the award. The 2008 Technical Excellence Award was presented to a team of researchers from Portland State University led by Professor W. Robert Daasch, and supported by students Liwei Ning (PhD 2009), and Amit Nahar (MS 2006) for their research, "Burn-in Reduction: Improving Outlier Screening".
