Research is one of the foundational pillars of our simulation center. STRATUS has primarily focused on becoming a world leader in the study and application of human factors and cognitive engineering sciences in healthcare.

Simulation is one of the innovative methods the STRATUS research team has used to understand and improve human performance in a variety of settings, including emergency medicine, critical care, surgery, and space missions. Our focus is to develop novel tools and technologies that enhance learning, professional skills, and patient safety.

Human Factors and Cognitive Engineering Lab

The Human Factors and Cognitive Engineering lab at STRATUS, led by Dr. Roger Dias, brings together a multidisciplinary team of clinicians, engineers, psychologists, computer scientists, and educators, including collaborations with several scientists and institutions, nationally and internationally. Our research projects have been funded by the NIH (R01), NASA, DoD, NSF, and AHRQ.

Mission of the Lab

The core mission of our research lab involves the use of cutting-edge technologies to understand and improve clinicians’ performance, with the ultimate goal of enhancing patient safety and improving clinical outcomes.


Our research lab uses advanced technologies including:

  • High-fidelity simulation
  • Artificial intelligence and machine learning
  • Digital biomarkers
  • Wearable sensors
  • Data science and visual analytics
  • Virtual, augmented, and mixed reality
