Biography
Hello! My name is Ryoko. It's a pleasure to meet you!!
I'm a third-year PhD student. I'm currently establishing advisor relationships and starting to work on understanding AI metacognition and simulating variable annuity portfolio features in actuarial and insurance contexts. I'm also interested in enumerative combinatorics and number theory (especially in a math contest-y style!)
I've TAed for many of the mainstream calculus courses and am currently grading a variety of geometry and nonlinear programming courses.
I look forward to broadening my horizons during my time here!
Research Interests
Still exploring! I've been dabbling in number theory (mostly analytic) and enumerative combinatorics, as well as actuarial science and AI metacognition.
