I'm currently a researcher in the HCI group at Huawei Canada (Noah's Ark Lab), where I study multimodal interaction and natural user interfaces. I received my PhD in Computer Science from Ontario Tech University, supervised by Dr. Christopher Collins. During my PhD, which was fully funded by CAPES, I investigated perceptual and statistical issues that influence the effectiveness of data plots.
