Data scientist and researcher with senior programming skills

Profile Summary

I finished my doctoral degree in digital signal processing and informatics at the Brno University of Technology in 2018. Since 2014 I have been working at Brain Diseases Analysis Laboratory where I became excited about advanced signal processing and machine learning applied in the field of neurosciences. Since 2017 I have also been working at Inventurist.ai where he discovered the beauty of natural language processing and AI/data-driven product development. In 2019 I co-founded a pool of experts from academia and industry with expertise in machine learning.
