Boise State University

The focus of my teaching at Boise State University has been in the areas of engineering graphics, machine design and computer-aided design. I teach the freshman engineering graphics, sophomore introduction to mechanical design, junior applied mechanics of materials and kinematics of machinery, and senior machine design. Additionally, I teach mechanics of materials for mechanical and civil engineering students. I also teach an elective course in computer-aided design.

The focus of my research at Boise State University has been on use of innovative design technologies to assist Idaho industries with their new product development processes. This has been through demonstrating virtual simulation of product geometry and performance using computer-aided design and computer-aided engineering software. It has also involved using rapid prototyping to demonstrate creation of physical models to verify product form, fit and function.

This research has been supported through two Economic Development Administration grants targeting small and rural manufacturers. The College of Engineering, College of Business and Economics, and TechHelp Idaho have joined in collaboration to make this work possible. To sustain this effort, a New Product Development Laboratory was established within College of Engineering that is supported in part by offering design services to companies on a reduced fee basis.

Availability of Fused Deposition Modeling (FDM) and Stereolithographic Apparatus (SLA) has allowed us to explore use of rapid prototyping to create pre-operative spine and pelvic models for complex orthopedic surgeries. This effort has been in collaboration with Intermountain Orthopaedics of Idaho. Models have now been created for orthopedic clinics through out the United States.

North Dakota State University

I taught undergraduate courses in machine design, mechanics of machinery, mechanical vibrations, computer-aided design, numerical methods, simulation of mechanical systems, dynamics, and mechanics of materials. Taught graduate course in advanced dynamics of machinery. Supervised graduate research and industry-based senior-design projects. Initiated successful proposals to industry resulting in development of computer-aided design laboratories and a computer-aided manufacturing facility. Updated the existing curriculum by integrating design technologies such as finite element methods, computer graphics, reliability, and optimization.

J.I. Case Company

I provided design recommendations to engineering managers for the development of new agricultural and construction equipment aimed at maximizing operator safety, efficiency, and comfort. Supervised field evaluations of equipment to analyze operator performance and functional requirements -Comprehensive guidelines on human factors design for new operator compartments developed based on these evaluations. Supervised design of full- scale operator compartment mockups for human factors evaluation – finalized mockups were used as a basis for production design. Supervised development of research instrumentation and techniques to evaluate operator tasks, visibility, biomechanical effort, and environmental stress – as a result, more sophisticated analyses could be made of operator performance, workload, and safety.

Wayne State University

I supervised research which yielded basic information on tolerance to impact and acceleration. Developed electronic instrumentation to measure acceleration, force, strain, and electromyographic signals. Developed computer programs that simulated the response of the human body to external forces. Numerous publications resulted from this research – Agencies sponsoring this work included the National Institute of Health, Department of Transportation,and Institute of Highway Safety.

U. S. Army-Tank Automotive Command

I supervised development of experimental pumps, burners, and heat exchangers for automotive heating systems. Evaluated performance characteristics of vehicle elements such as heaters and radiators.
