Summary

I have 30+ years industry and research experience in the areas of custom engineering software (e.g., CAD/CAM/CAE), object-oriented technologies, middleware (e.g., client/server, publish/subscribe), patterns (e.g., architectural, design, idiomatic/language), computer simulations (e.g., using the Distributed Interactive Simulation (DIS) protocol and the Test and training ENabling Architecture (TENA)), distributed realtime embedded (DRE) systems, and quality of service (QoS).

I have 9+ years experience teaching computer science (CS) at the collegiate level and in recent years have become more involved with CS education at the K-12 level with College Board's AP exam grading (CS-A and CS Principles) and consulting/training with the National Math and Science Initiative (NMSI). I'm also a member of IndianaComputes which is a consortium of Indiana collegiate faculty members working to enhance and deepen K-12 CS education in the state of Indiana and beyond.

In 2011, I received my Ph.D. in computer science from Vanderbilt University in Nashville, TN under the advisement of Dr. Douglas Schmidt and Dr. Aniruddha Gokhale. I am currently a faculty member of Indiana Wesleyan University in Marion, Indiana where I teach computing science courses and conduct related research.

My Ph.D. dissertation of ADAptive Middleware And Network Transports (ADAMANT) focused on the following areas of QoS for publish/subscribe middleware:
With the Hinds Research Fellowship at IWU awarded to me for the 2017-2018 academic year (and extended into the 2018-2019 academic year), I researched Information Extraction of paper-based meal attendance systems. This work was in the context of easily transitioning a charitable non-profit community-based organization from being paper-based to leveraging electronic information to reduce errors and increase productivity.

With the Hinds Research Fellowship at IWU awarded to me in 2014 and renewed in 2015, I extended my ADAMANT research by investigating artificial intelligence (AI) approaches and their applicability for adaptive DRE systems. With my supervision in this research area IWU undergraduate students developed the content for, wrote, and presented "A Taxonomy of Artificial Intelligence Approaches for Adaptive Distributed Real-time Embedded Systems"
