My field is human-computer interaction (HCI).
My research seeks to
scientifically understand people's interactions with computers and information, and
to improve those interactions through design and engineering,
especially for people with disabilities.
Interaction is my phenomenon of interest—studying and shaping it
to create better user experiences.
My specific research topics include
human performance measurement and modeling,
HCI research and design methods,
mobile computing, and
I pursue Ability-Based Design,
where the human abilities required to use a technology in a given context are questioned, and
systems are made operable by or adaptable to alternative abilities.
