Ergonomics and Computational Human Operations (ECHO) Lab
The goal of ECHO lab is to improve the lives of professionals by leveraging novel technologies to enhance their performance; therefore, their interactions with others and society. Within the human factors and ergonomics discipline, we aim to measure data from humans to develop models to assess skills and implement interventions to improve teams’ performance, particularly in healthcare environments.
- Surgical human-robot interactions
- Individual and team skills performance assessment
- Applications of robotics in healthcare
- Behavior and physiological modeling for training and interventions
