Andrea Cassano-Piché, Human Factors Engineering Consultant, is a licensed Professional Engineer and holds a M.A.Sc (2006) in Industrial Engineering, specializing in Human Factors Engineering. Since 2003, Ms. Cassano-Piché has applied her human factors training to the health care context. Her work has focused on procurement and implementation of health technology, health technology design and evaluation, proactive risk management (e.g., failure mode and effects analysis), the development of patient safety systems and culture, and teaching human factors methods.

Ms. Cassano-Piché has led national projects on complex topics such as ambulatory intravenous chemotherapy safety and multiple intravenous infusion safety, which culminated in nationally and internationally recognized recommendations on clinical practice, technology design, and education. She is the lead author of the book Human Factors for Health Technology Safety (2015) available at www.ifmbe.org.

Her strong desire for continuous learning and her ability to quickly build a rapport with clients, allowed Ms. Cassano-Piché to extend her consulting expertise to the aerospace industry where she is currently supporting the design of human-machine interfaces for the ground control operations of the CanadArm 3 on NASA’s Deep Space Gateway – a lunar orbiting space station with a goal of extending human presence at a larger distance from Earth.
