Roger Boldu

PhD Candidate

I am a Ph.D. student at the Augmented Human Lab (AHLAB). My research focuses on designing novel input-output wearable devices that enable users to interact with the environment naturally. I like to bring my research beyond the laboratory environment and positively impact people’s lives by combining my skills in HCI, Robotics, Machine Learning, and Electronics.

I graduated with a B.Sc.(Honours) in Electronics and Telecommunications from Ramon University - La Salle Bonanova, Barcelona, Spain in 2015, and I have conducted HCI research at Auckland Bioengineering Institute (ABI), Massachusetts Institute of Technology MIT Media Lab, and Singapore University of Technology and Design (SUTD).

I am now looking for full-time positions to start from May 2021. For more details, visit my personal website:
