Summary
👤
Senior🎓
Top SchoolChristopher Ni is a quantitative researcher and former astrophysicist with over a decade of experience in image and time-series analysis, now applying those skills at Citadel Securities. He earned a PhD from the University of Toronto studying the earliest observable phases of thermonuclear supernovae, where his work revealed for the first time stratification of nuclear burning products in the outer 1% of ejecta and reshaped models of explosion physics. Christopher has built and optimized high-throughput discovery pipelines for multi-telescope networks, led gravitational-wave follow-up tools, and routinely designs software from scratch as well as integrates and mentors others on analysis extensions. His background blends rigorous mathematical training with production-grade engineering and a track record of translating subtle, early-time signals into population-level astrophysical insight—an unusual bridge between academic discovery and quantitative systems work.
