Meet the Founder, AI Ethics Network

IMG_3056.JPG

I’m Rivkah Singh — software engineer, former mathematics professor, inventor, published author, and founder of the AI Ethics Network. With over a decade at Microsoft and Tableau, I specialized in engineering, client enablement, training development, and making complex systems accessible and practical.

​

As a former Professor of Mathematics at Miami Dade College, I designed tech-integrated curricula to strengthen quantitative reasoning and critical thinking. I hold a patent-pending method for visual composition via advanced Euclidean constructions and am the author of four books, including Grok and I: Harnessing AI for Personal and Professional Transformation (2025).

Through the AI Ethics Network, I advocate for responsible AI — especially ethical companionship that offers reliable, compassionate support for aging adults, neurodiverse individuals, those facing isolation or chronic conditions, and others needing safe, non-judgmental presence. Priorities include transparency, bias mitigation, mental health safeguards, privacy, and preserving human dignity without replacing meaningful connection.

​

I also guide educators and institutions on ethically integrating AI for personalized learning, accessibility, equity, data privacy, and pedagogical integrity — ensuring it supports teachers and promotes inclusive student outcomes.

Via consulting, workshops, research, and collaboration, I help build AI solutions that emphasize safety, accountability, and genuine human benefit in companionship, support, and education.
