About Me

I am an HCI Researcher at Reality Labs Research at Meta.

Previously, I was a Postdoctoral Fellow in the Dynamic Graphics Project Lab at the University of Toronto working with Professor Tovi Grossman. Before that, I was a researcher at the Visualization and Intelligent Multimodal Interfaces Group at INESC-ID Lisbon under the supervision of Professor Joaquim Jorge. I received my PhD, MSc and B.Sc. degrees in Computer Science and Engineering from Técnico Lisboa / University of Lisbon.

In my research, I have been designing and evaluating novel interaction techniques for the engineering, architecture and medical fields, focussing on computer supported remote collaborative work in Mixed Reality environments. I also have experience in 3D user interfaces, interactive spaces, touch and mid-air gestures.

I have been fortunate to see my research published in top international conferences and journals, such as ACM CHI, ACM UIST, ACM ISS, ACM IUI, ACM VRST, IJHCS, Computers & Graphics, IEEE TVCG, IEEE ISMAR, and IEEE VR.
