About Grant

As a Principal Research Scientist and a Certified Usability Analyst, Grant Leffingwell supports human factors (HF) research and development programs for government, healthcare and commercial industries. He understand how users cognitively and practically interact with technology, in particular with medical systems, drug delivery devices and software interfaces.

Grant applies this knowledge to assist in the design, development and human performance evaluation (testing) of devices and interfaces, including formative and summative human factors studies, often conducting these efforts in the context of stringent regulations and quality engineering systems. To do this, he works closely with clients, stakeholders and other HF experts and testing facilities, and coordinates with engineers from many disciplines to ensure proper HF implementation in their solutions.
