About My Work
I focus on intelligently leveraging technology to enhance the training, assessment, or application of knowledge and skills.
I oversee the design, development, testing, and delivery of cutting-edge applications that address challenging real-world needs to ensure their reliability, engagement, and usability.
With over two decades of experience, I address real-world challenges by designing cost-effective applications, always prioritizing end-user needs. My work combines:
• Advising clients on technology strategies • Staying informed about emerging tech trends • Developing innovative, user-centered applications • Managing research from design to presentation • Mentoring diverse and interdisciplinary teams My work has addressed a range of areas including medical consent, clinical social skills, consumer decisions, law enforcement, and survey nonresponse. I bring a strong foundation in computer science and cognitive psychology with a focus on data analytics, shaping practical applications of artificial intelligence, mixed reality, and machine learning.
• Experimental design—Expertise in data collection, harmonization, statistical methods, and predictive modeling
• User engagement—Capturing the needs and experience of the different end users • Data science—Emphasizing FAIR elements, safety, explainability, and trustworthiness in all projects • Human subjects research—Proficiency in ethics, testing, survey design, and user persona development • Strategic communication—Clear articulation of methods and findings for diverse audiences, from practitioners to decision-makers Professional Experience
WOC (Without Compensation) Appointment, 2018–2021
Veterans Affairs Medical Center, Center of Excellence for Suicide Prevention Teaching Assistant Professor, 2017 North Carolina State University, Department of Computer Science Adjunct Professor, 2000, 2016–2017 Duke University, Department of Psychology Senior Technical Consultant, 1987–1990 Andersen Consulting EducationPh.D., Cognitive PsychologyDuke University M.S., Computer Science North Carolina State University S.B., Computer Science & Engineering Massachusetts Institute of Technology
I have extensive experience in developing situated training and assessment systems, working with subject-matter experts to design appropriate and focused systems. Examples: Evaluating the cost-effectiveness of simulation training systems; developing adaptive intelligent tutoring; developing intelligent virtual advisors; developing an information-processing model of experts' knowledge and skill; exploring augmented cognition and user-sensing technologies for simulation training systems.
Additional information is found here in my portfolio.
I have developed behavioral software that enables virtual humans to act and behave realistically in controlled learning contexts. I have investigated models of cultural daily activities and patterns of life integrated into simulations of intelligent virtual humans. Sample of applications developed: Assessing medical practitioners in history taking for both asthmatic and pediatric patients; training civilian police officers in how to handle mentally disturbed individuals; training telephone and field interview staff in obtaining respondent participation; virtual vignettes to assess social functioning deficits in at-risk youth.

I have developed applications focused on medical and clinical settings; training clinicians on difficult content and skills, augmenting their practices by providing simulation environments to capture important diagnostic details, and improving patients' understanding of processes and procedures.

I have investigated visual analytics, which allow for looking at data prospectively and visually. I have studied mental models to ultimately develop training to encourage adaptive thinking about test, measurement, and diagnostic equipment, to develop the structure and process of knowledge and skills and to identify differences between experts' models and novices'. I have modeled emotion in and extracting emotion from dialog. I developed a process model for alternative representations and investigated the interaction between expertise and representation.

Across many project I have sought to define or change status quo. I have focused on novel approaches to inform training, education, and assessment, including simulated environments, extended reality, wearable systems, and AI techniques. I have influenced design and development of technical systems by studying, eliciting, and adopting end users' perspectives. I have recently focused on core competencies needed by professional students and evolved educational methods to meet the needs for rapidly advancing work settings.
