I’m Jose Luis Silva, Postdoc in Artificial Intelligence at Linköping University (Sweden). I hold a Ph.D. in Physics from Uppsala University. I am all in to solving real-world problems at scale. I have Co-Founded Oxaala Technologies (AI Company) which recently raised 1.6M+ SEK through the CNPq/MCTI Startup 2022 Brazilian Call to develop an AI-based software prototype for Exploration Geophysics. I was also granted the VFN Grant 2022 at LiU for further development of initiatives in collaboration with the Industry. I was a Chair at NeurIPS 2021 for the Workshop LatinX in AI, current member at LatinX in AI, and peer-reviewer for the NeurIPS, CVPR, Elsevier, and Gulf Arab Journal of Scientific Research covering AI & Machine Learning. I am also writing a book chapter regarding Advances in Artificial Intelligence and Data Mining.
