Short biography

Dorothy LuiI completed my bachelor’s in Mechatronics Engineering at the University of Waterloo in 2012. I am now pursuing my master’s in Systems Design Engineering under the supervision of Prof. Wong. I was first exposed to image processing while working on in vivo bone implant images to determine bone porosity at the UW Rapid Prototyping Lab. Then, I worked at Colibri Technologies applying digital signal processing to ultrasound images.
