My research interests are diverse, but there's substantial holistic coherence and overlap: software and hardware systems engineering, especially aviation-related; modeling, simulation, visualization, and analysis; artificial intelligence (knowledge representation, reasoning, machine learning, and natural language processing); and STEM education. This presentation at Graduate Colloquium provides a colorful overview of recent activities. More info is available in my curriculum vitae.
In particular, I consider these areas collectively as the complementary basis of intelligent systems:
Software and Hardware Systems Engineering
I'm a systems engineer at heart (and by MSE degree). Computer science is my primary discipline (by Ph.D. degree), but I'm equally at home with electrical and mechanical engineering; i.e., using computers to control electrical systems that interact with mechanical systems. As the projects below show, I'm definitely a field engineer, down and dirty — even bloody — with every aspect of analysis, design, fabrication, testing, deployment, maintenance, etc.
Although I work on diverse systems-engineering projects, my passion is aviation. As an avid airplane and helicopter pilot, I enjoy both the thrill of flight and the underlying science, engineering, and technology. Washington state, being Boeing Country, is a natural fit.
Modeling, Simulation, Visualization, and Analysis
After modeling and simulating hundreds of weapon systems on Department of Defense projects over a decade at White Sands Missile Range, Aberdeen Proving Ground, and elsewhere, I have a strong background in using these tools and techniques in almost all my work. I view them as a complementary bundle:
At varying degrees of complexity and difficulty, I teach my undergraduate (CSCD 350) and graduate (CSCD 524) Software Engineering courses based on this framework. The undergraduate course primarily addresses analysis, design, and implementation, whereas the graduate course focuses more on Software Quality Assurance. I also have a new undergrad/graduate course on modeling and simulation (CSCD 439/539) scheduled for Winter 2017.
Artificial Intelligence / Intelligent Systems
Modeling, simulation, visualization, and analysis for engineering are typically a quantitative effort. I'm also fascinated by the qualitative aspects:
Simply put, I love to share what I have learned and experienced. This passion is evidenced by the 35+ periodicals I voraciously read and pepper my courses with as endless case studies and current events. Over my academic career, students have continually expressed how radically different my courses are from what they're used to. Some appreciate it at the time, others not, but many have contacted me after graduation thanking me for the unique preparation. Furthermore, in my first year of eligibility as a professor, I was already awarded the highest teaching honor. In addition, I have over two decades of consistent, substantial contribution to STEM-related recruitment, retention, and outreach activities at all age levels.
My research philosophy evolved by having unreasonable workload demands, but few or no resources, throughout most of my academic career. I've learned to develop an idea as a research project first, then apply it the classroom environment for teaching purposes (or vice versa), often resulting in simultaneous parallel publication streams in both venues, and hitting three birds with one stone.
There is actually a more current project for adaptive electromechanical stability control (as of spring 2017), but this project below is still ongoing.
In addition to a number of research projects below that are still in progress, my current focus is on machine learning of helicopter flight dynamics. Helicopters are extremely unstable machines: an input to any control induces numerous direct and indirect inputs into every other control, which in turn affect the entire system in an endless battle to maintain stability. Learning to fly such an unruly beast takes long, hard hours of expensive, supervised practice. A textbook definition of cause-and-effect relationships is helpful for overall understanding, but nothing replaces practical trial-and-error experience.
The objectives of this work are threefold:
The goal of this work is to develop not only a software system that can fly a virtual helicopter, but also one that can articulate how it learned to do so. It has practical applications to autonomous flight and to human flight training. Follow-on work could be extended to comparable model helicopters for real-world experimentation.
There are several aviation-related grant opportunities I plan to pursue to help offset the cost of this work, especially through the Joint Center for Aerospace Technology Innovation (JCATI), in addition to the EWU seed grant I was awarded for 2014-15. Acquisition of real-world data must be repeated many times to mitigate a variety of experimental errors, which entails hours of costly rental time.
This list showcases some of my research and projects that I have photodocumented recently. A lot needs updating, and there are entire projects missing. There are many more projects from before this time without pictures. I also have a ton of software projects, but there's nothing very interesting to look at, at least compared to the colorful hardware projects.
