Caleb Vatral

Graduate Research Assistant

Institute for Software Integrated Systems




Caleb Vatral joined the OELE lab as a teaching assistant in Fall 2019 and transitioned to a research assistant role in Fall 2020. They are currently pursuing the PhD degree with a focus in intelligent systems in the department of computer science at Vanderbilt University, working in the Institute for Software Integrated Systems. Before attending Vanderbilt, he received the BS degree in computer science and mathematics from Eastern Nazarene College, Quincy, MA.

Caleb’s research focuses on multi-modal data-driven approaches to support cognitive modeling and system design in human-centered simulation. They utilize Bayesian models and methods which are grounded in theories of distributed cognition. By linking low-level observable data collected from mixed-reality simulation based training environments to higher-level cognitive, metacognitive, and psychomotor strategies and skills, they generate comprehensive evaluations of learner performance at both the individual and team levels.

Current Projects: 

  • Teamwork modeling and assessment of soldiers using GIFT
  • Modeling and assessment of nurses in smart manikin-based training
  • Collaborative learner modeling in C2STEM
