About Me


Over the past years I have gained practical and strategic experience working with the full (classical and quantum) Machine Learning pipeline. I have 20+ patents issued or pending, 5+ papers published (Springer, IOPS, IEEE, ACM, Arxiv), and communicated the topic of (classical and quantum) Machine Learning across all organizational layers of various Fortune 100 companies.
