Dr. Marisa Mohr

About Me

I am a mathematician, Team Lead, and Head of Research & Development at inovex. My passion lies in mathematics — whether in artificial intelligence, data, or mathematical modeling. Mathematics is more than just numbers and formulas — it is a key to understanding the world. Especially in AI, it is crucial to ensure that it remains interpretable, explainable, and fair. My focus is on demystifying and explaining mathematical concepts to make AI more transparent and promote equal opportunities for all people.
