About me

Hi! I'm Rafael. I'm a Lecturer at University of Leeds, and a research collaborator of different labs. Previously, I studied at Técnico Lisboa   (where I also received my BSc, MSc and my PhD in Information Systems and Computer Science). There, I worked with the Visualization and Intelligent Multimodal Interfaces Group at INESC-ID Lisbon. Current interest topics are image and video-based rendering, 3D reconstruction, real time rendering, and XR.

I've previously worked as a postdoc at Unviersity College London at the VECG group, and at Victoria University of Wellington at CMIC. I still collaborate with both labs in my research.

For more details about who I am, what I like, and what I do, I'd encourage clicking the social networks referenced near my portrait or in the contacts section. They will do a better job than some words here. For anything else, you can send me a nice e-mail which will be replied as soon as I hit F5 on Gmail waiting for those journal paper reviews.


Projects and Labs


"Gait training using smart insoles and immersive reality technologies (XR)" is a new project funded by the sfti challenge in New Zealand. I'm working now remotely as an external advisor to Nadia Pantidi, who is the Principal Investigator at CMIC.

"Graphics Pipelines for Next Generation Mixed Reality Systems" Ongoin project at VECG,with which I collaborate. The Pipelines project is an EPSRC funded investigation into new graphics techniques and hardware. The goal is to re-purpose and re-architect the current graphics pipeline to better support the next generation of AR and VR systems.


   CMIC is a lab funded by the TEC in New Zealand, with a focus on Industry collaboration and commercialization. There, I worked mainly in sesveral small projects with japanese partners Square ENIX and IMAGICA on several projects related to their production pipeline. I also collaborated with the XR researchers in the lab in teleconferencing.

   Blackbox was an interdisciplinary ERC-funded project hosted by FCSH-UNL from September 2014 to 2019. On this project, I was mostly interested in the capture and representation of information of the human performers, which goes through point-cloud data capture and rendering, and building technology that will help people from different areas draw conclusions about the deeper meaning of what is there represented.

  REngine was a short-term collaboration with the IT-medex to develop a Unity3D solution for volume rendering (3D Textures) and surface rendering (meshes). The goal was visualizing volume data reconstructed from medical images (CT, MRI, etc), and render using a raymarching shader.

  Machinima Storyteller was a project funded by beActive with the goal of creating a Machinima from an input movie script, in an interactive environment where a game-like experience could be later developed. It was developed using Unity3D, with intelligent agents doing the interpretation of the parts.

  Target was a serious game project focused on conflict resolution in business scenarios. I developed part of the the AI component of the platform.



Computer Graphics - Universidade de Lisboa - Técnico Lisboa

2016, 2017 and 2018
Teaching two different group of students, supervising an OPENGL 2.0 / C++ project, or Javascript 3D (three.js)

Foundations of Modelling and Rendering - University of Leeds

Mathematics, Physics, Computing that are the basis of computer Graphics. Diving deeper than what is done at the undergraduate level, students are introduced to modern pipelines, raytracing, and many other fundamental concepts. This module is part of the High-Performance Graphics and Games Engineering MSc.

User Interfaces - University of Leeds

Undergraduate module (year 2) where students are taught basic user interface design, from a theoretical and practical viewpoint. They are also introduced to C++ at this module, which I was in charge of teaching.
