Ellen Bass



Health Systems and Sciences Research

Ellen J. Bass, PhD, has decades of human-centered systems engineering research and design experience in healthcare, air transportation and other application domains. Her research focuses on developing theories of human performance, quantitative and qualitative modeling methodologies and associated decision support and visualizations that can be used to design and to evaluate human-automation interaction and human-human collaboration in the context of total system performance.

Bass's research contributions can be decomposed into four synergistic areas:

  • Characterizing human judgment and decision making.
  • Modeling human judgment when supported by information automation.
  • Computational models of human-human coordination and human-automation interaction.
  • Design and evaluation of interventions to improve human judgment and decision making.

Research outcomes can be used in the systems engineering process: to inform system requirements, procedures, design support tools, control and display designs and training interventions and to support system evaluation.

She has published over 100 peer-reviewed publications and has contributed to four National Academies of Sciences, Engineering and Medicine reports. She is the founding editor in chief of the IEEE Transactions on Human-machine Systems. She serves as a peer reviewer of several international research programs.
