Sharareh Sayyad

“I am a mathematician and theoretical physicist working at the intersection of artificial intelligence, mathematics, and physics. I am currently a Ph.D. candidate in Mathematics at Washington State University, having previously earned a Ph.D. in Physics from the University of Hamburg. My current research focuses on AI-driven discovery in mathematics and physics, and on incorporating high-level mathematical structure, such as topology and geometry, into machine-learning models to make them more explainable, interpretable, and efficient. Before turning to AI, I spent a decade working on quantum many-body and non-Hermitian physics, publishing more than 20 papers in leading journals. Along the way, I have enjoyed collaborating with researchers around the world, mentoring students, and organizing a global seminar series.”
