Gabriel Leivas Oliveira

Brief Bio:

I am a Lecturer in Artificial Intelligence at the School of Engineering Mathematics and Technology from the University of Bristol and an ELLIS member.

From February 2019 to March 2025 I was a Machine Learning Researcher and later Team Lead at Borealis AI Vancouver - Borealis AI.

From September 2014 to February of 2019 was a Ph.D. student from University of Freiburg supervised by Professors Thomas Brox and Wolfram Burgard. Mainly research deep learning approaches to robotics perception.

I hold two masters degrees, both in Computer Vision and Robotics, from the University of Minnesota and the Federal University of Minas Gerais (Brazil), respectively.
